A Buffalo mother reportedly inflicted fatal injuries on her five-month-old daughter. The baby died of severe head trauma.

Denay Foster, 24, of Buffalo has been sentenced to 20 years in prison plus five years post-release supervision by Erie County Court Judge Sheila A. DiTullio for causing the death of her baby, according to a press release from the office of Acting Erie County District Attorney Michael J. Flaherty, Jr.

In May, Foster pleaded guilty to Manslaughter in the First Degree.

“This mother was unremorseful and indifferent regarding her daughter’s well-being,” acting DA Flaherty said in the release. “She waited several hours before she took the injured baby to the hospital, but by then, it was too late.”
