CANTON, Ohio -- A toddler was shot to death as he slept alongside his twin brother, becoming the third person killed in the city during a six-hour wave of gun violence that began Tuesday night and stretched into Wednesday morning.

Nineteen-month-old Ace Lucas lie sleeping on a living room sofa alongside his twin brother, Arcel Lucas, at 2:28 a.m. Wednesday when shots rang out at their home in the 1600 block of Clarendon Avenue SW.

Neighbors said they had heard a car rev its engine loudly and then heard gunfire.

A woman who called 911 reported that someone fired at least seven shots into her home and she can be heard telling an emergency dispatcher that a baby had been shot in the butt.
