The burned bodies of two women and a man were found by police on a dirt road in the central Mexican state of Morelos, prosecutors said.
The bodies were found early Saturday some 150 meters (about 490 feet) from a municipal building in the city of Huitzilac, the Morelos Attorney General's Office said.
The victims were about 80 percent burned and had been gagged, the AG's office said.
Another body was found in Xochitepec, a city in Morelos, media reports said, adding that the victim was shot in the head.
Numerous murders have occurred in Morelos recently, with the killings linked to drug trafficking. EFE
