Bensalem police have reported that the 18-month-old girl involved in the investigation of Adrian Allen has died.

She died early this morning.

Allen, 27, of Gooseneck Road in Bristol Township, was arrested last week on first-degree felony aggravated assault charges, child endangerment and related charges.

Allen was baby sitting his girlfriend's three children at her apartment in the 2500 block of Knights Road. He called her on Feb. 26 and told her that her daughter was sick and vomiting. When she returned home that day she found her daughter unresponsive in her crib and took her to St. Mary Medical Center. The child was then flown to St. Christopher’s Hospital.

Allen was lodged in Bucks County Prison after Bensalem District Judge Leonard Brown set his bail at $1 million/10 percent.

Sgt. Andrew Aninsman said the investigation is on going and a press conference is scheduled some time in the beginning of next week.
