EDWARDSVILLE, Ill. (AP) — A southern Illinois man has been guilty of first-degree murder in the death of his fiancée’s son on the boy’s fifth birthday.

It took a Madison County jury nearly six hours of deliberation before finding 27-year-old Tavon Ludy of unincorporated Glen Carbon guilty in the September 2013 death of Torian Whitaker.

The Belleville News-Democrat reports Lundy was also found guilty of aggravated battery for beating Torian’s older brother, Zajamin. According to prosecutors, Ludy admitted to punching Torian in the chest because the boy disobeyed him.

Ludy allegedly picked up the boy after hitting him and took him to the home’s basement, where he laid for at least 10 minutes before someone called emergency personnel.

Prosecutors say the boy’s mother, Toria Coleman, was out shopping for a birthday present for her son at the time of the incident.
