NEW YORK (CBS 2) — A Brooklyn woman and her live-in boyfriend have been charged in the beating death of the woman’s young son.

The boyfriend, 31-year-old Reginald Williams, has been charged with second-degree murder, while the toddler’s mother, 27-year-old Teresa Foster, faces charges of criminal possession of a weapon and endangering the welfare of a child.

Police responded to a 911 call from 41 Kingston Avenue in Bedford-Stuyvesant just after 10 p.m. on Friday night. When they arrived, they found two-year-old Aiyden Davis covered in bruises and unresponsive.

The little boy had been left Williams’ care.

A neighbor said he heard the baby crying – and had heard rumors of abuse.

“His friend heard something going on,” the neighbor said. “He was actually hearing, you know, this guy abusing the baby, yelling at him and spanking him and whatnot.”

The medical examiner had ruled the death a homicide, citing blunt impact injuries to the head, torso and extremities as the cause of death. Liver lacerations and internal bleeding were also found.
