The man suspected in a May 2000 shooting that killed eight Mexican city officials was arrested Tuesday in Sacramento, the U.S. Marshals Office said.
Investigators say Genaro Olaguez used heavy weaponry to carry out the attack in Sinaloa, Mexico.
U.S. Marshals say Olaguez was found living with family along Grove Street in Sacramento. He was arrested without incident, aside from initially giving investigations a false identity.
Olaguez was also arrested for a cultivation of marijuana warrant out of San Joaquin County, and the alleged theft of utility services.
