Cody Wygant, 24, of Homosassa about 50 miles north of Tampa is being held without bail, the Citrus Count Sheriff's Office said. He was arrested Thursday and charged with third-degree murder and child neglect.
Daymeon Wygant was pronounced dead at Seven Rivers Regional Medical Center after paramedics were called to the home just after 8 a.m. Thursday. Wygant and his girlfriend originally told deputies they found the boy unresponsive about an hour after putting him into his playpen.
Wygant eventually told a different story, investigators said. He allegedly admitted that at about 1 a.m., when Daymeon's crying bothered him, he covered the boy's mouth and nose with his hand for three or four minutes and then put him in his playpen covered from head to foot with bedding.
He said he spent the next five hours playing video games on his XBox and watching three episodes of the TV show "Fringe."
Wygant, who is unemployed, said he was alone with the boy and was Daymeon's primary caregiver. The couple's other child, a 3-month-old girl, was removed from the home by social service workers.
