Some fire and police investigations wrap up fast – some don’t. For the ones that don’t, we check back with the investigating agency from time to time. Here’s what we found on two such checks:

That was the aftermath of the fire that tore through an Arbor Heights house near 35th/108th on May 25 (original WSB coverage here), seriously injuring one man. Information on his condition was never been made available to media; privacy laws were invoked while he was in the hospital. We asked Seattle Fire Department spokesperson Dana Vander Houwen if the fire’s cause was ever found – short answer, no. It will remain on the books as “undetermined.” That’s also the result of the investigation into this one, another fire in May:

A neighbor shared that startling photo from the May 3rd early-morning house fire in the 1700 block of 44th SW (original WSB coverage here). The house was empty and listed for sale; no one was inside; no injuries were reported. Vander Houwen says investigators ultimately could not find the cause of this one either, and it will remain on the books as “undetermined.”
