A fatal fire is under investigation in Union Gap.

Union Gap Police Detectives will be back at a home searching for clues Tuesday after two people were found dead in the home following what authorities say was a suspicious fire on Sunday. Union Gap firefighters were called to the home at about 2:50 a.m. Sunday. The home was located in the 2200 block of South Fifth Avenue in Union Gap. The fire destroyed the home. A press release says the homeowner survived the fire. He was treated at a local hospital and released. Investigators are talking with him trying to figure out what happened and what started the fire.

After the flames were doused police investigators found the two bodies which have not yet been identified. The Yakima County Coroner Jim Curtice is working to find out who they are and trying to contact family members before identities are released.

However six people were in the home when the blaze was reported so three people are still missing. A news release says the homeowner and "several people" survived the fire so it's not yet clear if firefighters and police have actually found at least some of the three people who are missing. The search continues Today. It's not known if others escaped the fire or if their bodies have not yet been found. The investigation continues Today as fire and police officials get back to the scene. It's a burned out structure and investigators say it's a challenge to look for answers in the material.  More Information about the fire is expected Tuesday.
