MEXICO CITY Mexican authorities say six people have been found alive with their hands cut off in the western state of Jalisco, along with another person who was killed.

State Prosecutor Eduardo Almaguer says the victims were discovered Monday evening outside an event hall in Tlaquepaque, which is on the southern outskirts of Guadalajara. He says they range in age from 24 to 44 and include six men and one woman.

Investigators believe the mutilations and the killing were revenge for an unpaid drug payment involving members of the same cell of a criminal group.

Almaguer said Tuesday that “this is a settling of accounts between them.”

Two suspects were detained, and the victims were being treated for their injuries.
