MEXICO CITY, May 18 (Xinhua) -- Mexican authorities found five bodies Saturday in an abandoned vehicle left outside the police offices in the municipality of San Juan de Sabinas in the northern state of Coahuila, the local government said.
In a statement, the Coahuila public security department said local prosecutors had opened an investigation to identify the five victims and recover evidence.
The vehicle was abandoned in the early hours of Saturday outside the headquarters of the investigative police, a police arm of the prosecutor's office of the Coahuila state.
According to local media reports, the vehicle was left after gunmen fired shots outside of the building.
Coahuila is one of the Mexican states with the lowest homicide rates. But between 2011 and 2013, the number of murders climbed due to fights among drug cartels for control of their border with the United States.
