When the officers arrived, they found Perez lying on the floor with what appeared to be a gunshot wound, investigators said.

Los Angeles City Fire Department paramedics responded to the location and transported the victim to a local hospital for emergency medical treatment, according to authorities. Despite life-saving efforts, Perez died as a result of his injuries a short time later.

Investigators said Perez was working in the convenience store as suspects entered the location posing as customers. After the victim walked to the register to assist the suspects, the first suspect jumped over the counter and produced a handgun demanding money from the cash register, according to police.
