TEPIC, Mexico, Oct. 27 (UPI) -- Gunmen drove up to a carwash in Tepic, Mexico, Wednesday and opened fire, killing 15 people, most of them recovering drug users, authorities said.
It was the third massacre in Mexico in less than a week.
Authorities said 13 of the victims worked at the carwash and most were enrolled in a drug rehabilitation program, the Los Angeles Times reported. A 14th victim was found dead at a fruit stand nearby and the 15th was killed while arriving on a motorcycle.
Three other people were wounded. The Times said a witness told W Radio men armed with rifles showed up at the carwash in two sport utility vehicles, got out and started shooting.
It hadn't been determined why the carwash workers were targeted.
On Sunday, 13 men were slain at a drug treatment center in Tijuana and on Friday, 14 were killed at a birthday party in Ciudad Juarez.
