Police are investigating the death of a 1-year-old child in Kensington

Philadelphia police are investigating after a 1-year-old girl died in Kensington Thursday evening in what police said appeared to have been a drowning.

Just after 7 p.m. Thursday, police responded to a 911 call to a house on the 1800 block of East Somerset Street, where they found an unresponsive child, police said. Paramedics took her to St. Christopher’s Hospital for Children, where she was pronounced dead.

At the home, police found a water-filled basin in the second-floor bathroom, police Chief Inspector Scott Small told CBS Philadelphia Thursday. The house’s dining room on the first floor was also soaked with water.

The department’s Special Victims Unit, which investigates sensitive crimes often involving children, is leading the investigation, police said Friday.
