A father has been found guilty in the death of a 16-month-old baby.

Dwayne Poole was found guilty of manslaughter and aggravated child abuse.

Tuesday, testimony against Poole included disturbing photos of the child's bruises.

Pediatric Critical Care Doctor Carl Riggs explained to jurors just how bad those injuries were.

"I thought he would die," said Dr. Riggs.

Police say Poole killed his son, Ronderique Anderson, in 2011 because he was playing near a light socket. Court documents say Poole punched the baby and threw him on a bed, which caused Ronderique to hit his head.

Police say Poole told them the baby fell down the stairs. Dr. Riggs described the injuries as disturbing, and testified the injuries didn't support that story.

"It seemed like all injuries were in alignment, sort of on the left side of the body, so the left side of his forehead, the spleen, the marks we saw on the leg and the trunk," said Dr. Riggs.

Poole's ex-girlfriend, Tonya Myers also testified Tuesday.

Myers pleaded guilty to child neglect charges for not reporting the abuse. Myers told jurors she lied when police interviewed her.

"The first statement was just a lie, period," said Myers, "because I was scared."
