The bodies of five people, at least four of them members of the same family, were found Wednesday in the suburban zone of the port of Acapulco, in the southwestern Mexican state of Guerrero, the state attorney general's office announced.

Officials with the state AG's office told Efe that about 8 a.m. (1300 GMT) authorities received a telephone call saying that bodies were lying near a corner on Loma Bonita St. in the Ampliacion Cinco de Mayo neighborhood.

Law enforcement personnel were dispatched to the scene and found four bodies, all with bullet wounds, among them that of a man about 30 years of age and identified as Joel Macario.

The other three bodies were those of two women about 20 and 30 years old and a child of about 3, all members of the Nava Hernandez family.

Police collected 17 9mm bullet casings and a .38 caliber shell, along with two deformed bullets and six bullet fragments, all of which were taken for study.

Some 10 meters (yards) from the spot where the four bodies were lying, in a house undergoing structural work and with its doors open, police found the body of another woman bearing fatal bullet wounds. She was identified as Mayeli Nava, 25.

According to the sources, a young girl was grazed by a bullet while walking near the site with her aunt while the massacre was under way. The girl is now being treated at a nearby hospital.

The state AG's office opened an investigation into the shootings, but so far authorities have not mentioned any possible motives for the multiple murder. EFE
