According to the Houston Police Department, it was around 8 p.m. when the 18-year-old was working at the restaurant and was shot in the neck by one of two robbery suspects.

Police said the victim’s mother was also working in the restaurant when the suspects walked in.

“During the robbery, it appears the black males entered the store, pointed a gun at a female employee who ended up being the victim’s mother. (The victim) tried to intervene and when he confronted the guy with the gun, he was shot.” said Detective David Crowder.

Emergency responders with the Houston Fire Department rushed Flores to Ben Taub Hospital but he did not survive.

Police said they don’t know if anything was taken in the robbery.

“They’re out here working and doing what they’re supposed to be doing and then these two suspects came in and cut that short and certainly there was nothing in there that was worth the life of the 18 year old.” said Detective Crowder.
