Mexico City, Jul 5 (EFE).- Seven males ranging in age from 12 to 24 were fatally shot in the southern Mexican town of Coyuca de Benitez, the Guerrero state Attorney General's Office said.
Municipal police received a call around 6:00 p.m. Thursday about the presence of dead bodies along an area river, the AG's office said in a statement.
At the site, police found six people dead and two others wounded. All eight had been shot in the head.
One of the injured - a boy of 12 - died later en route to the hospital, while the other remains in serious condition.
Found near the bodies was a nylon bag containing paint thinner and glue.
Residents objected when police tried to remove the bodies, prompting authorities to summon medical examiners, forensic technicians and detectives to start the investigation at the scene.
Early findings indicate the victims often gathered at the spot to consume illegal drugs and inhalants.
