SWEET HOME, Ore. -- The Sweet Home Police Department is still investigating a devastating mobile home fire and is treating it as a crime scene.
Multiple agencies were at the Tamarack Ridge Estates mobile home park all day Tuesday as they tried to figure out what caused a fire and the deaths of four people, two of them children.
Police said at least one of the victims showed signs of trauma not consistent with the fire.

Shawn Richardson, who lives nearby, said he heard a loud noise similar to a gunshot and then heavy running inside the home.
"It was definitely a loud pop," Richardson said. "It made it where I had to pause the TV and ask my girlfriend, 'Did you hear that?' While the TV was paused, I started hearing loud thumping."
Sweet Home Fire District responded to the 911 call around 6:50 Tuesday morning. Firefighters were able to put the fire out within minutes but they discovered four bodies inside.
Police said they are investigating the scene and looking at all possibilities. This is still an ongoing investigation.
One neighbor, Katie Jacks, said the husband was always very friendly. He even showed her some mobile homes he had remodeled.
"I'd always see him on his little moped, riding around the park," Jacks said. "He always waved when I'd go by him."
Sweet Home residents talked to KEZI 9 News about their reaction to the fire.
“I grew up in a trailer park, and I've seen trailers on fire and seen it jump from trailer to trailer," said Debbie Preston. "And so it really kind of scared me, because I know how fast they can go up in flames and jump from trailer to trailer."
Brandell Braatz, also a Sweet Home resident, said she didn't know the people who died.
"It's kind of scary, knowing that less than a block away -- and not just scary but it's sad -- because we should know our neighbors."
