Robert Marin, 60, faces first-degree murder charges in Phoenix, Arizona, after allegedly shooting his estranged wife Heather Marin four times in their garage around 9:30 p.m. on Monday, March 16, 2026. Their teenage daughter witnessed him standing over the body, smoking a cigar indifferently as she performed CPR and called 911 following Heather’s pleas of “Please don’t kill me.”
Incident Background
Tension stemmed from an argument over their daughter staying with Robert; he expressed hatred toward Heather during a verbal fight and made an angry call demanding she remove the daughter. The daughter heard screaming, pleas, and gunshots after ignoring Heather’s calls around 8:39 p.m. and 9:09 p.m.
Aftermath and Evidence
Robert shrugged off his daughter’s cry of “Why would you do this?!” walked out, then returned to smoke over the body; police found him bloodied with alcohol odor, dropping to his knees silently upon arrival. A gun, holster, casings, and his unsecured firearms collection—including prior threats noted by the daughter—supported premeditation claims.
Prior History
The daughter reported an unreported February 2026 domestic incident where Robert held a gun, threatening to shoot Heather then himself, plus hateful texts between them. He’s held on $2 million bond in Maricopa County Jail.
