LOUISVILLE, Ky. (WDRB) -- Indiana State Police say they have arrested a Salem, Indiana man and charged him in the death of an eight-month old boy.

24-year-old Jamie James Lykins was the live-in boyfriend of the baby's mother.  He was arrested at a convenience store on State Road 56 in Salem and charged with neglect of a dependant and battery causing death.

His mother found eight-month-old Leelan Crain unresponsive around 7 p.m. Saturday.  The mother, along with Lykins, took him to St. Vincent's Hospital in Salem.  From there, he was transported to Kosair Children's Hospital in Louisville.  He was pronounced dead at 1:41 a.m. Sunday.

An autopsy Sunday morning led to a preliminary determination of the cause of death as head injuries.  The final determination of the cause of death could take as long as six weeks. 

Neighbors tell WDRB News the couple's reaction after the alleged accident struck them as suspicious and that their story didn't seem to add up.  Another neighbor said she had suspected abuse before.

"She was sitting on the porch and she had a smile on her face, and I was like, your baby's in the hospital," said neighbor Nicole Moore.

It was Saturday night when Casey Crain and her boyfriend Jamie Lykins told neighbors Leelan was sleeping when he rolled off the bed at their home in Salem, Indiana.

Another neighbor, Matt Marion, tells WDRB News, "I asked him again, 'How did the baby fall of the bed?' and he said, 'Yeah, that's what happened'....You wouldn't think something like this would be that traumatic and would cause that much damage that it did."

Casey Crain's Facebook page shows a recent picture of the mother, her son, and her new boyfriend.  The same picture shows bumps and bruising on the baby's head.

Moore says, "A month to what happened now, the baby had a bruise around his face, its eye, and she said it was trying to get out of a swing."

She continued, "I heard them slamming doors, yelling, throwing stuff.  When the baby cries they'll turn up the music really loud."
