Authorities say two adults and a juvenile have been arrested after two people were found dead in a Tacoma house fire. The fire was reported at 2:45 a.m. Friday in the 3700 block of South Yakima Avenue, near Lincoln High School. Fire spokesman Joe Meinecke says firefighters arrived to find the home in flames. During a post-fire search, they discovered the bodies. Both appeared to be adults. Detectives with Tacoma police said Tuesday the fire was intentionally set and it is being investigated as a homicide. The two adults are being held in the Pierce County Jail — one for investigation of 1st degree murder (two counts) and 1st degree arson, and the other for rendering criminal assistance.
