PHILADELPHIA (CBS) — Police say a 2-year-old girl was killed in a triple shooting in Philadelphia’s Kensington section Sunday afternoon. The shooting happened on the 3300 block of Water Street, just after 3:30 p.m.

According to police, an unidentified gunman was outside and shooting into the home, striking three people. Police say the home was targeted but it is not clear who was the exact target.

No arrests have been made.

Police say a 2-year-old girl was shot once in the back of the head and was pronounced dead at the scene.

“No child should be murdered in their living room. It’s just terrible,” Acting Philadelphia Police Commissioner Christine Coulter said.

“I can’t even process what’s happening,” Evelyn Torres, the girl’s aunt, said.

The child’s 24-year-old mother was shot once in the right side of the head and once in the back. She is in stable condition.

A 33-year-old man doing renovation work inside the home was shot once in the stomach. He is in critical condition.

“It’s heartbreaking. Any crime or anybody shot is a horrible thing, but when people indiscriminately shoot and kill babies or shoot babies, it’s unexplainable,” Coulter said. “I can’t imagine someone thinking at any time to fire a gun, but to do it with the thought that there are or could be children involved, it breaks my heart.”

Officers at the scene say the gunman used an AK-47.

Coulter said the ballistic evidence found at the scene is similar to evidence found at a second shooting scene about a half-mile away on the 400 block of East Clearfield Street where a car was shot up.

That shooting happened just five minutes before the deadly house shooting.

“We haven’t connected it yet but we’re certainly looking at — it’s close in proximity,” Coulter said.

The shooting comes a day after an 11-month-old baby was critically injured in a shooting in the city’s Hunting Park section. A $5,000 reward is now being offered for information leading to an arrest in the case.

Philadelphia Mayor Jim Kenney released a statement Sunday night about the two shootings.

“I am outraged, disgusted, and heartbroken by the violence this weekend that claimed the life of an innocent 2-year-old and left another infant fighting for his life. My prayers are with their families and communities during this tragic time,” Kenney said.

Anyone with information is urged to call police.
