Florentino Aparicio said not a day goes by that he does not have flashbacks of the day he lost four of his co-workers.
Aparicio said 50-year-old Ronald Davis got out of his car and started shooting. When Aparicio pushed one of his co-workers out of the way, he was hit in the back.
When the rampage was over, Davis had killed three co-workers, before turning the gun on himself.
The Montgomery County Sheriff said Davis targeted four men he thought were mocking him in Spanish.
Through a translator, Aparicio said he can't understand what would cause Davis to explode.
"He said he don't know what he's talking about because he never talk to him in Spanish," Aparicio's cousin Cesar Trejo said. "They used to get along pretty good and worked together as a team."
Aparicio faces months of therapy, but is expected to make a full recovery.
