Investigators announced the charges against Dominique Smith, 19, and and Abdul Johnson, 17, on Thursday.
Johnson was charged as an adult. The suspects were held earlier in the day on unrelated charges.
However, after he was charged, police say Johnson managed to briefly get away.
On his way to the Delaware County prison around 4:30 p.m. Thursday, police said Johnson jumped out of a law-enforcement vehicle near the prison.
He allegedly got into a another vehicle and, while still wearing handcuffs, led police on a short chased that ended in the city of Chester.
Johnson was arrested, taken back into custody and transported to the Delaware County jail.
The victim, 49-year-old /*Kathy Stewart*/, was in bed when she was hit in the head by a bullet that came through a wall and a headboard on Sunday night. She was caring for her mother, who is stricken with cancer, in her home in the 300 block of Franklin Street.
Sources tell Action News that Smith and Johnson were looking to 'even the score' with someone who lives next door to Stewart. The two suspects fired into that person's home, and the home Stewart was in. Police say she was, in no way, the target of the shooting.
Stewart died on Tuesday.
"It's crazy, it's senseless. My sister is just laying in bed, and people are just shooting in the projects," said Stewart's brother, Jerome, on Thursday. He said when police came to tell the family about the arrests, he was brought to tears.
Stewart's daughter said, just knowing that two suspects are in custody is comforting to her.
"I'm happy that they found the people and everything," she said. When asked if she thought this would help the family get over the death, she said "No" then added, "But it's a start."
As police continue the investigation, anyone with information on this case is asked to call 610-447-7931.
