Jutta Chambers of the Henderson Police Department said late Saturday it is believed the three men may still be in Southern Nevada. Hospitals throughout the area were alerted for anyone seeking treatment of a leg wound.
Police say one of the suspects was shot by one of the guards.
Two suspects opened fire on the guards with automatic weapons Friday as one guard got out of the vehicle at a Ross Dress for Less store in Henderson, on the southeast side of Las Vegas. Both were pronounced dead at the scene. Sosa was the father of five children. Chambers said the men fled the area in a dark mini-van or sport utility vehicle, possibly with Texas license plates. This was well-planned.
