Lisa Cosenza, 51, was killed on October 12, 2017, at her home in Aliso Viejo, California, during a violent confrontation that also left her longtime boyfriend, Douglas Ferguson, 59, dead. The confrontation reportedly began when Douglas Ferguson urged his son, Luke William Ferguson, to find work and stop drinking. Luke Ferguson, 26 at the time, opened fire inside the house, killing Lisa and Douglas and wounding two other men, ages 23 and 48, who survived with serious injuries.

Luke Ferguson fled the scene and was captured the next day in Inglewood after a police pursuit. He was found in possession of another firearm stolen from his father and charged with multiple counts including two counts of first-degree murder, two counts of attempted murder, firearm enhancements and special circumstance allegations of multiple murders. The prosecution said the killings were carried out with premeditation and malice. He was later convicted and sentenced to life without the possibility of parole plus an additional 84 years and four months to life.
