Michelle Hashtani, 28, of Vista, California, was shot in the head at her apartment complex on Ascot Drive on July 22, 2018. Deputies found her gravely injured near the complex swimming pool around 3 p.m.; she underwent emergency surgery but died of her wounds on August 3, 2018.

Authorities quickly identified her boyfriend, 43-year-old Estevan Montelongo, as the prime suspect. He was arrested two days after the shooting in Pueblo, Colorado. Montelongo had a prior domestic violence conviction from 1999 involving another girlfriend, a history the prosecution emphasized during the later trial. He was charged with first-degree murder and associated firearm and prior-felony enhancements; the jury found him guilty and he received an 80 years to life sentence.
