BLOOMFIELD (KDKA/AP)- Police say a 16-year-old male and 20-year-old woman were slain by a home invader, who was fatally shot by another person in a Bloomfield apartment.

Around midnight, officers were called to an apartment building in the 200-block of Mathilda Street.

When officers arrived, they found a man and a woman inside a first floor apartment. They were both pronounced dead at the scene from gunshot wounds.

“Upon further investigation, officers found a third victim who was in the backyard of the house here,” said Pittsburgh Police spokeswoman Sonya Toler.

The Allegheny County medical examiner says the victims inside the apartment are Jaimill Kenney, a teen visitor from Pittsburgh who attends Pittsburgh Milliones School, and the woman, 20-year-old Akeilah Solomon, who lived in the apartment.

The body of 25-year-old Kadeem Williams, of Homestead, was found shot behind the apartment building.

Pittsburgh police believe Williams entered the apartment through a bathroom window and exchanged gunfire with an uninjured victim inside the apartment. Police haven’t released that person’s name or said whether they will be charged.

“At this stage of the investigation, we believe the uninjured victim is one of the people who were shooting inside the residence,” said Toler.

“We heard that it was a home invasion. Other than that, we haven’t got any information. We’re just waiting for the police to do their investigation,” Kieshah Cain Saunders, Solomon’s cousin, said.

Neighbors reported smelling drugs and seeing lots of people in and out of the apartment in recent weeks.
