The three suspects arrested in the September stabbing death of 15-year-old Derek Juarez-Lopez are all now charged with first-degree murder: 18-year-old Jonatan Islas-Martinez, 17-year-old Elizabeth Cabrera-Aparicio, and 16-year-old Diego S. Carballo-Oliveros, all three of whom live in West Seattle. (The latter two are charged as adults, so we are publishing their names.) The charging papers say that Carballo-Oliveros already was facing charges of robbery and attempted robbery in an unrelated case, and was due in court the day after the murder that led to these charges.
The narrative in the charging documents is largely the same as what we reported yesterday from the documents in Islas-Martinez’s probable-cause hearing, with a few additions: Prosecutors describe Cabrera-Aparicio as Carballo-Oliveros’s girlfriend, but also had written that she was the victim’s girlfriend. Also, the documents quote an unidentified witness as saying he went to Westcrest Park with Carballo-Oliveros with the expectation they were going to buy and smoke marijuana, and they awaited “the dealer.” The victim showed up with Cabrera-Aparicio and showed a glass jar that was in his backpack, “just enough of the jar that would clearly show that it was filled with marijuana, which, according to (the witness), is a common practice when purchasing an ounce of marijuana, which was the case in this transaction.” (The witness) said that as soon as Carballo-Oliveros saw the marijuana, “he demanded everything” from the victim, who resisted – and then, the documents say, was stabbed by Carballo-Oliveros, who had removed a “medium-sized knife” and flipped it open. The victim tried to run but was pushed down from behind. Islas-Martinez then grabbed the backpack and ran, the witness said, while the victim remained on the ground and Carballo-Oliveros allegedly said, “That wasn’t supposed to happen, I don’t want to have to kill you.” He then ran, said the witness,who did the same thing, saying he didn’t realize the victim was hurt.
Next steps in the case: All three defendants are scheduled for arraignment November 2nd. Bail for each is now set at $1 million.
