A Teenager Is Shot And Killed In A Shootout. Philadelphia

More than 80 shots were fired in a shooting that claimed the life of a teenage boy and triggered a brief barricade situation Thursday night in North Philadelphia.
 Officers from the Philadelphia Police Department were called to the 3400 block of Palethorp Street for reports of gunfire.
Police found A. C. S. suffering from multiple gunshot wounds to the body and rushed him to Temple Hospital where he died. Responding officers took three persons of interest into custody, including two on foot and one person found in a black pickup truck.
A SWAT team was called to the scene for reports that two males had barricaded themselves inside a nearby garage. Authorities breached the garage, but did not find anyone inside. Investigators at least 80 shell casings were found at the scene and appeared to have been fired from at least two different guns - including an AK47-style short rifle and a handgun. Both guns were recovered at the scene.
Police used so many evidence markers at the scene that they were forced to hand-make additional markers.
