LOUISVILLE, Ky. (WDRB) -- Louisville Metro Police say a Louisville man tried to kill his girlfriend's 15-month old son inside their apartment on South 16th St. "No, he (the toddler) wasn't moving," recalls Kasie, a neighbor. "He just had an oxygen mask on his face."

Kasie's voice was still shaking as she described paramedics putting the toddler in the ambulance. "The ambulance driver had him in his hands and when he was carrying him out, his head was back. He looked like he was asleep or passed out or something."

Police say Roderick Williams was alone with the toddler for hours on Friday as the child's mom ran errands. Neighbors spoke of pictures taken of him during his first birthday, dressed with Mickey Mouse ears. "He was cute," says Kasie.

Investigators say at some point the 6' 9'', 235-pound boyfriend grabbed the boy and shook him for two minutes, but police say the abuse went even further.  "He allegedly slammed him into the crib," says LMPD spokesman Dwight Mitchell.

Williams told homicide investigators he then held the boy down in his crib until he called 911. Doctors at Kosair Children's Hospital say the boy's injuries are life threatening -- bleeding on the brain, a skull fracture and broken ribs, a lacerated liver, and bruises all over his body.

"Something very tragic has happened," says Mitchell. "Happened to people who can't defend themselves when something comes of this nature. That's what greatly concerns us."

Williams pleaded not guilty during his arraignment on charges of attempted murder and assault. His bond sits at $100,000 cash.
