Luis Bracamontes was born on June 8, 1970, in Mexico. 

On October 24, 2014, Luis Bracamontes, using the name Marcelo Marquez, committed a series of shootings in the Sacramento area. He began by opening fire on sheriff's deputies. Deputy Danny Oliver of the Sacramento County Sheriff's Department was killed in the Arden-Arcade neighborhood. Bracamontes then carjacked several vehicles. During this time, he shot a driver. He later encountered police officer Detective Michael Davis of the Placer County Sheriff's Department in the Auburn area. Bracamontes fatally shot Davis and seriously injured Davis' partner.

After the shootings, there was a significant manhunt for Bracamontes. He was eventually captured and taken into custody. The legal process that followed lasted about four years. Bracamontes often disrupted court proceedings with outbursts. In 2018, he was sentenced to death for his crimes.
