Vigil Planned For Young Mother Killed In Front Of Newborn In East Germantown

Their 5-day-old newborn girl was in the same room at the time of the shooting. She was unharmed.

Police say there was no forced entry but there appeared to be a struggle as furniture had been overturned.

Detectives revealed that Lynch had two priors: a DUI and a domestic dispute with Williams from a year ago. That case was later dropped.

Police say they’re glad Lynch is off the street.

“It’s terrible. It’s still a 5-day-old baby that now has no mother or father. It’s terrible all around,” said Philadelphia Police Capt. John Ryan.

A cousin of Isis spoke during an emotional candle light vigil that was held Monday night.

“I just want to say something about domestic violence. If you’re in it please get out. Don’t stay. Don’t stay it’s not worth it,” said Isis’ cousin. “Everybody should be there for one another,” said Isis’ cousin. “There is no way that woman should have been in there screaming and nobody called. Say something, call the police, bang on the door, something! Somebody do something so we’re not standing here holding balloons and candles for another person.”

Williams’ three children are in the care of her family.
