CRIME WATCH FOLLOWUP: Charges filed against suspect in Leticia Martinez-Cosman’s disappearance, but her fate remains unknown

2:28 PM: Three days after initial word of what led police to 46-year-old Brett M. Gitchel in connection with the disappearance of Leticia Martinez-Cosman, the King County Prosecuting Attorney’s Office has charged him with Attempted Murder In The First Degree, Kidnapping In The First Degree, Unlawful Possession of a Firearm in the Second Degree, Theft In The First Degree, Arson In The Second Degree. (We obtained the 2014 mugshot of Gitchel at right from the state Department of Corrections.) The charging documents say authorities still don’t know Ms. Martinez-Cosman’s fate; the attempted murder and kidnapping charges come from what they say he did to her special-needs adult son, as detailed in the probable-cause narrative we published on Friday. The arson charge is related to what’s also described in Friday’s narrative, the fire set to destroy one of Ms. Martinez-Cosman’s cars, found burning on Beacon Hill. We’re still reading the rest of the charging documents and will add to this story shortly.

2:52 PM: Prosecutors are asking for $5 million bail. Their documents also include this, based on cell data:

Historical data records also show that on the early afternoon of 4/01/2023, about 15 hours after Leticia was last seen alive at the Mariners’ game, Brett drove outside of the City of Seattle into a remote mountainous region in King County, stayed for a short period of time and then returned to Seattle, where about 12 hours later he would kidnap and assault her son and burn her vehicle. Leticia Martinez-Cosman is still missing, and though extensive social, public, and national media have drawn attention to this incident, no one has been able to provide evidence of Leticia being alive after she left the Mariners game with Brett Michel Gitchel.

As for when they left, the detective’s narrative in the charging documents says:

Security footage provided by the Seattle Mariners and T-Mobile Park depict Leticia and Brett staying to the end of the game and around 2230 hours walking together out of the park and into a nearby parking garage, where they walk up the stairs to the 3rd floor and walk together toward the parked vehicles. This is the last known footage of Leticia.

The detective’s narrative also notes that a gun was found in Gitchel’s Audi after his arrest – that’s the reason for the unlawful-firearm-possession charge, as he is a convicted felon, with a record listed in the charging document as including seven felonies – three from 2014 related to stolen cars, an eluding conviction that same year, and three felonies in the 1990s – two for theft, one for drugs. One final note from the detective’s narrative details additional security video seen by police:

In the evening of Friday, April 7th, 2023, SPD Detectives were able to view video from a neighboring home of the Martinez-Cosman home for the first time. Detectives located video that depicted Brett Gitchel walking to the front Leticia’s home on 4/01/2023 at approximately 1157 hours. Brett is alone and walks to the front of Leticia’s house out of the video frame and then about 13 seconds later walks back through the neighbor’s video frame away from Leticia’s home. This video footage depicts Brett at Leticia’s home, without her, approximately 13 1⁄2 hours after Leticia is seen leaving with him on the Mariners T-Mobile Park security video.

On Monday, April 10, 2023, SPD Detectives were able to locate and recover surveillance video from the Shell station at 2424 Beacon Av S. Video recovered included the date of 4/02/2023 where after 0600 hours Brett is depicted driving his 1999 tan Audi into the Shell station lot, parking near the gas pumps, removing a light colored jacket and placing it in the garbage, entering the Shell station and purchasing a new red 1 gallon portable gas canister in one transaction, going back and purchasing a lighter in a second transaction, returning to the pumps and filling the canister with fuel,
and then driving away in a northbound direction on 14 Av S. The timing of this activity is approximately 2 hours
after (Leticia’s son) escaped from Brett in Renton and a little more than 30 minutes before SFD responded to 904 Golf Dr S to extinguish Leticia’s burning vehicle.

The document does not elaborate on the “remote mountainous area” to which investigators believe Gitchel briefly drove. It does list a different “last known address” for him – last week’s document said Federal Way, but this one says Orting. Gitchel’s next scheduled court appearance is for arraignment – to enter pleas – on April 24th. Prosecutors note that the SPD investigation remains ongoing, so more charges are a possibility.

    Let him rot in prison. Sorry to sound harsh but he really doesn’t deserve another breath of sweet PNW air.

    • Lola April 10, 2023 (3:06 pm)

      Flimflam,  I am with you.  I hope he gets locked up for life.  The story just keeps getting more and more bizzare.  I hope they can find something about what he may have done with her?  I am glad her son got away. 

    • T Rex April 10, 2023 (3:36 pm)

      That is not harsh at all, in fact the many things I am thinking are much worse and cannot be published on this blog. This poor woman and her poor son.  God help them. 

      • sbre April 10, 2023 (5:44 pm)

      Just the kind of guy I’d want to date my grand daughters.

  • Friend off Roxbury April 10, 2023 (4:15 pm)

    My heart dropped reading the timeline of the location after leaving T-Mobile Field. I’m wrought with sadness for this loss and unfathomable anger at people who could do such an inhumane series of acts. This hits way too close to home for me. Leticia was in our lives for a reason. I choose to heal by embracing the seeming purpose she served on this earth.

  • Colonel Mustard's Wrench April 10, 2023 (4:16 pm)

    I am so very sad to hear about the missing woman, the kidnap/assault on her special needs son, and the burning of her vehicle.
    Prayers to her, and her family.

    As for BM Gitchell – I hope his cell mates welcome him in the same manner that he has treated Leticia, her son, and her car. 

  • Jennifer April 10, 2023 (4:39 pm)

    West Seattle Blog, thank you for reporting so much more information than other sources! So many are following this case closely and you all doing a great job!! 

    • Nebulae April 10, 2023 (8:54 pm)

      I could not agree more. WSB is doing an incredible job on the updates, there’s better information here than any other news source. 

  • Ferns April 10, 2023 (5:09 pm)

    Oooohhhhhhh. Pretty damning evidence (means) to buy and fill a gas canister and then have the nerve to go back in for a lighter. Cashier must have been a little curious.reminded me that As a teen I worked at a super store and got irked when teen guys would roll up to the checkout with just a couple of spray paint cans. Yeah, they could be helping family to paint the shed but are 100% headed out to tag or mural-ize some property that is not theirs later that night. The stores sometimes had age limits on those “art” supplies to deter graffiti or huffing by youth.I’d love to know about the suspects motive. Timing seems so odd. I’m exhausted at the end of a baseball game! Maybe we’ll find out he bought no-doz too. It’s just so strange he hasn’t confessed with so much evidence and priors. If they were in a relationship, I am willing to bet she was pregnant. women are most likely to be killed by their partners, and are particularly at risk during pregnancy. 

    • WSB April 10, 2023 (6:36 pm)

      Ms. Martinez-Cosman’s age has been noted as 58, so that latter speculation is not likely.

    • Portlander April 12, 2023 (3:36 am)

      From what I read, this was a first date and he was a stranger to her.

  • Oh Seattle April 10, 2023 (5:34 pm)

    Guy’s Twitter is a real ride.  At least there’s one less incel MAGA prowling the streets tonight.

  • Alki neighbor April 10, 2023 (6:41 pm)

    Does anyone know if the police are following up on this case? https://www.kiro7.com/news/local/body-found-near-snoqualmie-pass-identified-missing-tacoma-woman/ZU6AFSHEYZGGVD6DTY7WAMLHPI/?outputType=ampIt sounds just like this one :(

  • Joan April 10, 2023 (6:42 pm)

    This is so sad and disturbing. This man is a very sick predator and needs to be kept locked up away from the rest of us. It’s also a sad reminder that  women must always be careful and guard against people who will do you harm. I hate to be paranoid, but better safe than sorry. Kudos to the police for making such progress.

  • zipda April 10, 2023 (8:34 pm)

    Terrible human being.  I’m hoping Karma keeps receipts.

  • HS April 10, 2023 (9:42 pm)

    The attack on her son made me hopeful that Leticia may still be alive. This man exhibits all the traits of someone who would keep another person against their will. I’m hoping that she is found soon.

    • Elton April 10, 2023 (11:10 pm)

      I got the opposite from that interaction – the fact that this man was deranged enough to try to strangle a special needs individual shows that they are clearly very dangerous. Still, I sincerely hope that she is found alive.

  • bolo April 10, 2023 (9:50 pm)

    Too bad the car wasn’t a Tesla. Its cameras might have recorded important clues to solving the crime.

  • I’mcoveredinbees April 10, 2023 (9:56 pm)

    I’m gutted. Cannot stop thinking about this, her family, her SON, and her friends. I know her and she would never leave her son on purpose. She is the kindest, sweetest, and most fun loving person. It’s just horrifying… I want them to find her so healing can begin. We need to have a very big memorial for her—she touched so many lives. And it’s a small relief that they have him and with so much evidence. The way he was so blatant and arrogant in all his actions makes me think this was not his first rodeo. Prayers for Leticia and her family. 

  • D-Mom April 10, 2023 (11:58 pm)

    Thank you for the detailed update!  I have not been able to stop thinking about this poor family and have been checking multiple news sites more than once/day for an update. I want so much for her to be found alive.  Considering this man’s rap sheet and this case, I really hope they keep him behind bars for good. 

  • Mb April 11, 2023 (8:30 am)

    It is hard to process. Know that you aren’t alone as we all walk through this together. 

  • ttt April 11, 2023 (10:27 am)

    I hope he is in jail for the rest of his life. Thank you for the info WSB. Reading the the diana and callie cases, it does make one wonder if he is connected to those too. This guy is scum of the earth.

  • momosmom April 11, 2023 (11:00 am)

    This is such a sad, sad story and I’m hoping Leticia will be found alive.To all the people who have attached links to other missing/killed woman/burned up cars please call the Police and inform them of the similarities. The more that can be linked to this guy hopefully will put him away for life.

  • Duckie April 11, 2023 (1:58 pm)

    Didn’t want to post this earlier out of respect for WSB’s decision not to publish the suspect’s name until charged, which I totally understand.  According to an article,  the report in the WSB is being utilized in the police investigation.  I know several had asked about whether a possible connection was being looked into given the similarity of the individual’s appearance and dress in the video at the WS yard and in the picture from the Mariner’s game. Thank you WSB for all the work you do for the WS community.  It’s good to see that the excellent journalist work of the WSB is hopefully helping the police out in this case.

    https://heavy.com/news/brett-gitchel-leticia-martinez-cosman/. 

    From the article:

    Police are investigating whether there is a connection to a surveillance video showing a man prowling in a yard in the Genesee Hill neighborhood of Seattle. The video, recorded March 28, 2023, was posted by the West Seattle Blog.The man is wearing a Seattle Mariners jacket and looks similar to the man seen in the photo with Martinez-Cosman at the Mariners game. His appearance is also similar to mugshots and social media photos of Gitchel, but police have not confirmed if it is Gitchel in the surveillance video.According to a police report obtained by the West Seattle Blog, “Near the 54th and Genesee neighborhood. On 03/28/2023, at approximately midnight, unknown W/M entered the back yard and then hastily exited upon seeing security cameras. Unknown suspect returned at 0058 hrs. and attempted to gain access to the residence via the back door. Door was locked, entry was not obtained. Suspect then disabled the security cameras and cut the Comcast cable wires. Suspect was able to gain entry to a yard shed and steal an Echo backpack blower and an outdoor clock. Police report filed. # 23-84087.”

      Please note that “Heavy(dot)com” is just a clickbait aggregation site that lives on SEO – any time someone hits the news, you’ll see them turn up with something like “Five Fast Facts to Know About (Name of Heinous Criminal or Sudden Celebrity Here).” That aside, we finally have confirmation that police believe the Genesee Hill backyard burglar was Gitchel – while writing about the Renton body discovery, I checked his status on the jail register and found an additional charge just filed against him yesterday – the Genesee Hill burglary. Short part of this story but I’m adding the narrative once I’ve redacted the victim’s name and address specifics.

        Did not know that about heavy.com. Good to know. Thanks TR for providing an update on the Burglary and his involvement. WSB is the best!

  • GrittyGrits April 11, 2023 (7:36 pm)

    I was at that game. 😳 Hope the woman is OK.

  • Wsresident April 12, 2023 (9:02 am)

    What is the deal with men murdering women after Mariners games. Sick and unreal. I remember that one case where the woman was on a date with her boyfriend ant the game and they found her later chopped in bits in garbage cans. Scum of the earth. Sadly, he won’t spend his life in prison, as someone very familiar with murder case outcomes, there won’t be enough justice served. 

  • Mel April 12, 2023 (9:51 am)

    To Leticia’s family:  please let us know how we can help support you.  The blog is a good way to get word out. We are here and ready.

    • WS Res April 12, 2023 (11:16 am)

      Yeah, has anyone started a GoFundMe for the son? (Obviously only someone reputable/close to the family.)

      • TimD April 12, 2023 (1:38 pm)

        Hi, I am working on one on behalf of the family and will post it here once complete. I am setting it up so funds go directly to the family, so need that info first. They are taking care of Patrick (her son) and dealing with all of this today, but I’ll post it as soon as possible. 

      • Christine April 12, 2023 (2:04 pm)

        Good question. How can we help the son? He is in a very difficult situation. 

      • Amie Lee April 13, 2023 (2:53 am)

        I am a little worried about the go fund me thing. If Patrick is special needs and on the state radar.. they (the state) will take anything over 2k of funds in his name……….  I think someone needs to stop the gofundme thing….. it could hurt him more than help…..  I have a special needs kid, on the radar, I know what I am talking about…  email me if you have questions….

  • ZR April 12, 2023 (8:33 pm)

    Leticia was a friend of my mom’s. We lived with her for a little while 20 years ago. I hope this human parasite of a man gets the death penalty. He doesn’t deserve to breathe. 

  • Amie Lee April 13, 2023 (2:48 am)

    Please have the family contact Washington State DSHS for the benefit of Patrick!  A family member who has him live with them can get paid to take care of him. If no family members are available for that, they can locate a group home that can take good care of Patrick. They will need to work through the state system either way……  Prayers for peace for the family, and  I am so so so sorry this has happened for them.

  • Liz April 13, 2023 (7:14 am)
