PBSO: Man who killed ex-wife told deputies he ‘deserves an award’ After years of domestic disputes, Steven Guarnieri told deputies he “deserves an award” for finally killing his ex-wife. The 56-year-old tried to kill himself, too, he told Palm Beach County sheriff’s deputies, first by cutting his wrists, then by setting fire to his ex-wife’s suburban Lake Worth house. He was alive and only somewhat injured Saturday morning when he greeted deputies at the door of Nancy Guarnieri’s home in the gated Winston Trails neighborhood. Deputies were doing a welfare check on Nancy, who hadn’t been to work in two days. That was because she was dead, Guarnieri said, and wrapped in a sheet. Deputies followed bloodstains to the bedroom, where Nancy’s body lay under a bed sheet that covered the numerous stab wounds that eventually killed her. Blood stained her face, torso and hair, according to a sheriff’s office report. She was pronounced dead at the scene, and not long after Guarnieri was arrested on a first-degree murder charge. He is being held without bond in the Palm Beach County Jail, according to court records. Nancy’s boss, who asked deputies to do the welfare check, told them that while Nancy was on vacation, her ex-husband had moved into her home. Her boss was nervous, according to a sheriff’s office report, because of the pair’s domestic violence history. Nearly eight years ago Nancy called 911 because her then-husband was drunk and threatening to kill her. Guarnieri was arrested, but never charged in that case, according to court documents. They couple divorced in 2010. The domestic violence, Guarnieri told deputies, had gone on for 31 years. It reached the breaking point when Nancy told Guarnieri he had 24 hours to move out. He first tried to smother her face with a pillow while she was asleep, Guarnieri told deputies. When that didn’t work, he used the three kitchen knives he had in his pocket to stab her to death, according to a sheriff’s office report. He was tired of paying for his ex-wife and their children, both adults, and was upset Nancy wanted him out of the house. So he killed her, he told deputies. Friends told The Post in the courtroom Sunday that Nancy was the mother of two adult children, a daughter and a son. She was a make-up artist and hairstylist.
