On the night of March 16, 2026, 50-year-old Heather Marin was shot and killed at the Waddell home she formerly shared with her estranged husband, 60-year-old Robert Marin. The couple were separated and in divorce proceedings when the disturbance occurred near Olive Avenue and Perryville Road. Their teenage daughter, who was in the house, told investigators she heard her mother pleading for her life and then multiple gunshots, and she called 911.

Deputies from the Maricopa County Sheriff’s Office arrived about 9:30 p.m. and found Robert Marin in the garage with blood on his clothing and shoes; he was reportedly smoking a cigar. A firearm, a holster, and spent casings were located in the garage, and deputies noted a strong smell of alcohol on him. Court records and the daughter’s statements describe a pattern of domestic turmoil, including an alleged threat by Robert a month earlier to shoot Heather in the head and hateful, threatening texts; the daughter also confirmed her father owned multiple firearms. Robert Marin has been arrested and charged with first-degree murder and is being held on $2 million cash bond.

Did anyone in the neighborhood see or hear anything that night, or does anyone have additional information about the couple’s interactions in the weeks before March 16?
