Gangland violence has claimed five more lives here in Mexico's second-most-populous city, Jalisco state authorities said Friday.

The bodies of three men were found before dawn in Morelos, a neighborhood on Guadalajara's south side, sources in the state Attorney General's Office and the municipal police told Efe.

Two of the victims were decapitated.

The bodies and severed heads were bundled into trash bags bound with adhesive tape and dumped on a street near the office of a mutual aid association for Central American immigrants, the sources said.

A man of around 30 was found dead in the trunk of his car near a set of railroad tracks in El Salto, on the edge of the city. The victim's eyes were taped shut and his head was covered with a plastic bag, police sources said.

Carlos Bautista Garcia, 33, was killed in a drive-by shooting in the Guadalajara suburb of Zapopan. Struck by eight bullets, he was pronounced dead at the scene.

Several criminal outfits are battling each other for control of northbound drug-smuggling routes in Jalisco.

The main conflict is between the ultraviolent Los Zetas and a group calling itself Jalisco Nueva Generacion, but a gang based in the neighboring state of Michoacan, Los Caballeros Templarios (Knights Templar), is also trying to gain a foothold in Jalisco.

A score of police and civilians have died in the past two weeks in violence linked to the Caballeros. EFE
