Philadelphia police are asking for help with finding a man wanted in connection with the Grays Ferry mass shooting that left three dead and nine injured on July 7.

Philadelphia police say the deadly Grays Ferry mass shooting was a case of 'contagious gunfire' and a total of 13 guns were fired indiscriminately. One suspect has been arrested and charged in the incident.

Another suspect has been identified in the mass shooting last month in the Grays Ferry section of Philadelphia that left three people dead.
