Police are investigating a shooting that left two in critical condition early this morning, Chief Inspector Scott Small said.

The two victims, a 17-year-old male and 18-year-old female were sitting on a couch in a house on 45th Street near Brown about 1:45 a.m. when someone opened fired on the home's windows.

A total of eight shots were fired from a large caliber, semi-automatic handgun,  according to Small, with both victims being struck twice in the torso.

Medics on the scene took the male to the Children's Hospital of Philadelphia and the female to the Hospital of the University of Pennsylvania, where they remain in critical but stable condition, according to Lt. John Walker of Southwest Detectives.

Small said that, given the nature of the crime scene, it's clear that the shooter was targeting the house.

"This wasn't a case of stray bullets hitting someone," Small said. "Some of the ballistic evidence we found was just three feet away from the windows."

The shooting occurred while three other people were home, Small said, including a 9-month-old boy and the male victim's 51-year-old grandmother. Neither were injured.

No information on a suspect or motive is available, according to police, and investigators are currently reviewing footage from surveillance cameras in the area.
