Witnesses say the mother of the two young children, 9 and 7 years old, tried to run into the blazing structure to rescue them, but it was too hot -- she was rushed to a local hospital and treated for burn wounds.
A man in Florida has been accused of killing two children and setting the trailer they were in -- which turned out to be his own trailer -- on fire, with police believing it was all an effort to cover up the man's sexual assault of one of them.
The victims, Vayden Orum, 9, and Rayden Smith, 7, were allegedly spending the night at 27-year-old John Henry Walston Jr.'s trailer to play with Walston's own kids, according to their father, Tyler Smith.

View StorySmith told CBS affiliate WEAR that he and his wife had known Walston "for a couple of years" and that both families lived in the same trailer park in Escambia County. Smith is Rayden's father and Vayden's stepfather.
"How can you expect any human being to do this? Let alone an adult with two kids," Smith told the news station of the suspect. "John, I hope they give you hell in prison, because you better be glad they found you before I did."
The fire was first reported just before 1 a.m. on November 7, according to the Pensacola News Journal. Walston was arrested the following day.
Witnesses reported the mother of the two children attempting to run inside the fully engulfed trailer. "She went into the trailer trying to get them. That's a mother's love," neighbor John Wenzel said, per People. "She went inside the house trying to get her kids, but [it was] too hot. They finally got her out of there."
According to the news station, Walston started the fire early Friday morning after the two children had already been killed. Police believe he killed both siblings after sexually assaulting one of them. He then reportedly set the fire and fled the scene.

After attempting to rescue her children, their mother was rushed to the hospital where she was treated for burn wounds. Walston was also treated for injuries he'd received before his arrest.
The children's grandmother, Lisa Pinegar, spoke with WEAR over the weekend, calling their deaths a "bad dream." She then shared the conversation she'd had with the victims' only surviving sibling over the phone when she first learned about the whole tragic ordeal.
"He said, 'Mommy has been life flighted to the hospital. My brother and sister is no longer here, they're dead,'" she recalled. "He just kept telling me over and over and I didn't believe it. I didn't want to believe it.
