Bronx District Attorney Darcel Clark and elected officials led a silent march Wednesday night through the scene of a June 21 shooting that left three people dead.

It began with prayer and ended at the intersection of Randall and Castle Hill avenues, where police say a gunman shot two 33-year-old men in the head and a 45-year-old woman in her chest.

Police say the suspect is still on the loose. The NYPD is offering a $10,000 reward for information in the case.

"We need the community's help to get this man — who shot three people in broad daylight — off the streets," Clark says. "We can't do it alone."

According to a police source, the shooting may have stemmed from a domestic violence incident involving one of the victims and the gunman's daughter.

Not all of the victims were intended targets, according to the source.
