A suspect was arrested near the Arizona border with Mexico in connection with the deaths of nine U.S. citizens - six children and three women – Monday who were living in a Mormon community about 70 miles south of Douglas, Ariz., investigators said early Wednesday.
The victims’ convoy came under fire during the day in an ambush by gunmen believed to be affiliated with a drug cartel in Mexico.
The Agency for Criminal Investigation said in a statement on Facebook the suspect was found in the town of Agua Prieta, right across the border from Douglas, Arizona. The suspect was holding two hostages who were bound and gagged inside a vehicle. Investigators found four assault rifles and a bulletproof SUV.
Officials have said that the gunmen may have mistaken the group's large SUVs for those of a rival gang amid a vicious turf war.
