Deputies responded to The Siesta Key Bungalows, located at 8212 Midnight Pass Road, just after noon on Tuesday. The 39-year-old victim, said she told Benevento she would have to vacate the property, but the woman became angry, broke off a landscaping light and stabbed her in the stomach with the pointed end of the stake. Witnesses say the suspect then threatened a bystander with the same weapon.

Benevento was immediately taken into custody and has been charged with one count of Aggravated Battery and one count of Aggravated Assault.

The victim is being treated at Sarasota Memorial Hospital for non-life-threatening injuries.
