“We have to take a stance; we have to take our streets back,” said Renee Goodson, of the East End. “These mothers are crying. I mean there hearts are broken, they’re broken, they’re empty. These are babies dying out here in the streets for no reason. They’re senseless, either retaliation or because of where you live, the gun problem, the drug problem.”

Meanwhile, police are looking for suspects in two other murders.

Michael Mone-Parrotte, 17, was shot to death in Hunter Park in Wilkinsburg last week during an attempted robbery, and no arrest have been made in the murder of Donte Hawkins, a Clarion University student who was killed early Sunday morning at the Trappers Club in Larimer.

“We have got to step up as a community,” Laura Duncan, of the East End, added. “We’ve got to get off our couches, come out, get together, brainstorm and figure out a way to stop the violence. We’ve got to save our children.”

In addition to the homicides, at least six others have suffered gunshot wounds from various shooting incidents in communities in the city and county during the past week.

Anyone with information that can lead to an arrest is asked to call police.
