Mexican gang bosses sent commandos aided by local police to kill dozens, possibly hundreds, of people, murder them and dump their bodies near the Texas border in 2011, according to a government-backed report released Sunday.
The Associated Press reports in one town, all the men murdered had the same last name: Garza. The gang bosses were reportedly mad at suspected traitors.

According to the AP, government-backed documents show that state and federal officials ignored the massacre for years.
Because of how long ago it happened, it's hard for officials to determine how many people were killed. Documents list 42 names, but a Zeta drug cartel member testified that 300 people died.
The report, according to the AP, said that police helped detain some victims--or if they didn't, ignored calls for help.
The gang encouraged neighbors to loot victims' houses and destroyed some buildings with bulldozers.
The town where this happened, Allende, sits along a strategic drug route. The Zeta cartel reportedly paid local police $5,000 a month for their cooperation.
