2 dead and 3 wounded in shootings at four 7-Eleven stores in California, police say

Two people were killed and three were wounded in shootings before dawn Monday at four 7-Eleven stores in Southern California. Authorities said they were seeking one gunman in connection with at least three of the shootings.

The shootings appear to have occurred after robberies or attempted robberies at the four convenience stores on July 11, or 7/11 — a day when the national 7-Eleven brand celebrates its 95th birthday by giving out free Slurpee drinks.

"Our hearts are with the victims and their loved ones," 7-Eleven, Inc. said in a statement. "We are gathering information on this terrible tragedy and working with local law enforcement."
