ST. PETERSBURG, Fla. (AP) — Investigators say a fight over doughnuts led to a man to kill his mother’s fiance and wound a Florida sheriff’s deputy.

Pinellas County Sheriff Bob Gualtieri said it began Wednesday when 24-year-old Jeffrey Falsey asked his mother to get him doughnuts. When Susan DiFabbio refused, her son became angry. She called for help.

Gualtieri says shots rang out after deputies arrived, sending the deputies scrambling behind cars as Falsey watched from inside through a video surveillance system.

Two hours later, negotiators persuaded Falsey to leave the home. Inside they found 68-year-old Daniel Kulwicki dead. Deputy Michael Ficocelli was shot in the leg.

The sheriff says Falsey has mental health issues and had a “significant amount of firearms.” He faces multiple charges, including first-degree murder. Records don’t list an attorney.
