Man Pleads Guilty To Killing 4-Month-Old Son In Lower Bucks

LOWER BUCKS COUNTY, PA —A Bristol Borough man has pleaded guilty to killing his 4-month-old son and will face sentencing later this summer, authorities said.

Tyler Sullivan, 30, entered guilty pleas to third-degree murder and endangering the welfare of a child before Common Pleas Judge Gary B. Gilman, the Bucks County District Attorney's Office said. His sentencing is scheduled for August 27.

Officers with the Bristol Borough Police Department were dispatched at 11:35 p.m. on May 24, 2023, to the 1000 block of Radcliffe Street for a 4-month-old child in cardiac arrest.

When officers arrived, the baby was not breathing and was cold to the touch.

Police officers administered CPR, and the baby was transported to Lower Bucks Hospital where he was pronounced dead at 12:01 a.m.

A doctor examined the baby, noting the baby suffered several injuries, including contusions, bruising and abrasions throughout his body.

The doctor noted that the injuries were indicative of a battered child. The doctor also said the baby was already dead when he arrived at the hospital.

The investigation concluded that Sullivan violently shook the baby on at least two occasions on May 24, 2023, and at least six additional times in the six weeks prior, authorities said.
