On the night of November 28, 2022, 21-year-old Herminia Minnie Marquez was shot and killed in the 1100 block of 24th Street Lane in Greeley, Colorado. Officers who responded found Marquez with a gunshot wound; she was later pronounced dead.

Investigators focused on two people: Amos Alaniz and Mary Alicia Garcia. Authorities say the dispute arose over a stolen vehicle that Marquez and Alaniz’s sister would not return to him, and that Alaniz fatally shot Marquez. Garcia, 28 at the time, was identified as the driver of the getaway vehicle and was apprehended after a police pursuit in January 2023. Alaniz was 24 at the time of the killing.

The family described Marquez as a bright, loving daughter, sister and friend whose loss left them devastated.
