A mother and daughter were shot in their West Philly home. Police still don’t know why.

After two young men knocked on Kada Upshur’s door Wednesday night looking for one of her son’s friends, a calm discussion erupted into violence when one of the men shot at the 52-year-old mother six times, striking her and her 16-year-old daughter, Upshur said Thursday.

About 7 p.m. Wednesday, police and medics responded to a reported shooting on the 5700 block of Spruce Street and found Upshur and her daughter inside their home with gunshot wounds, police said.

Upshur was shot in her right hip and her daughter was shot in her right leg, Upshur said. Both were taken to Penn Presbyterian Medical Center and released overnight, she said.

Back at Upshur’s home Thursday afternoon, remnants of the shooting were still visible.

Chalk circles marking where shell casings had fallen ran from the sidewalk up the front steps. Shards of glass from the front door were strewn all over the steps. A plywood board was affixed to the door where the glass had been and a bullet hole fractured a window.

Upshur, still shaken, held back tears as she recalled the shooting from hours prior. Her daughter yelped as she hobbled back up the stairs, still in pain from her injury.

On Wednesday night, the two men knocked on Upshur’s door and one of them asked for one of her son’s friends, the mother said. After checking to make sure the friend was not in her house — he had stopped in earlier Wednesday to use the bathroom — she told the man asking for him that he was not there, she said.

It’s then when the young man quickly grew agitated, punching his fist, and threatening Upshur’s son’s friend and her son himself, she said. As she told the man not to threaten her son, Upshur stepped partially out of the doorway, and the man told her if he caught either of the two teens, he’d kill them, she said.

“Saying that when he catches them, either one, they’re gonna fry him,” Upshur recalled.

As Upshur was closing the door, the young man pulled up his shirt to reveal a gun, and then shot at her six times, she said. A bullet struck her in her hip as she turned, and struck her daughter — who was standing behind her — in the leg.

The gunman then fled on a bicycle, she said.

Initially, police said a man matching the shooter’s description was apprehended a short time later and was positively identified by the victims. But Thursday afternoon, Capt. James Kearney, head of the police department’s nonfatal shootings unit, said a person of interest had been apprehended Wednesday and released overnight, with no charges.

As of Thursday, nobody was in custody for the shooting, he said. The motive was unknown.

For 20 years, Upshur has lived with and raised her family in the Spruce Street home, she said. It was a laid-back block, relatively safe and quiet, she said.

But the shooting had left her and her family in a state of shock, worried about their safety and retaliation, she said. Living on disability and a fixed income, Upshur said she didn’t know how she’d afford repairs to her front door.

“The cops think they solved the case, but who is there for me? Who will protect my home?” she said. “I still have to worry about my son going to school every day. And that’s a parent’s worst nightmare, when you don’t know if your kid is going to be safe, going to and from school.”
