Article Photos: Urban advocates say new gun control talk overdue 4/4

FILE - In this June 30, 2006 file photo, an investigator views one of three gunshot victims on 49th Street in South Los Angeles. A gunman toting an assault rifle got out of a vehicle and shot to death 10-year-old David Marcial, the boyâs 22-year-old uncle and a 17-year-old neighbor. Davidâs 12-year-old brother, Sergio, survived. In the wake of the Dec. 14, 2012 mass shooting at Sandy Hook Elementary School in the small town of Newtown, Conn., there is now much political discussion about gun control. For urban advocates, this new emphasis on gun control is long overdue. (AP Photo/Reed Saxon, File)
