Nicole Boston, 28, was one of three people found shot in the head and killed while they slept in a Denver parking lot on the morning of August 9, 2018. She, her husband Jerome Coronado, 39, and Christopher Zamudio, 45, were discovered in the 700 block of South Broadway, near a light rail station; police described the deaths as execution-style killings.

Investigators tied the killings to Maurice Butler, 38, also known by the street name Khaos. Butler’s GPS ankle monitor placed him at the scene, witnesses said Boston and Coronado had been hiding from him and feared him, and the couple reportedly owed him a drug debt of about $100 to $200. Coronado had been seen with a black eye in the weeks before the shootings, which he attributed to Butler. Butler was arrested in September 2018, tried, and in July was found guilty on three counts of first-degree murder and later sentenced to three consecutive life terms without parole. No clear motive was established for the killing of Christopher Zamudio.

Boston was the mother of three, had her first child at 16, lost the father of that child to a 2008 murder, and at 23 underwent a partial hysterectomy after an ovarian cancer diagnosis. She struggled with pain medication dependency and periods of homelessness; her mother had arranged to meet her days before the killings but Nicole never arrived.

Did anyone in the Denver area know Nicole or have information about her last days?
