NORTH FORT MYERS, Fla.- Thomas Trammell was arrested for allegedly stealing a necklace from a 91-year-old man, that had the victim's deceased wife's engagement and wedding rings on it.

The victim's daughter reported the incident because the 91-year-old man is unable to speak, due to medical condition.

She reported that her father was sitting in a chair in the carport, when she saw a stranger, later identified as Trammell, hugging him. When she confronted the 22-year-old suspect, he explained that he needed to get some prescription medication for his father.

As Trammell back away, the victim's daughter saw her father searching his neck area, using hand gestures and making noises that indicated to his daughter that his necklace had been taken. She also noticed that it was missing.

The woman stopped Trammell in the driveway, demanding the necklace and two rings back, to which he replied that he didn't have them. Trammell turned his pockets inside out, revealing syringes and a small knife. Then, he fled on foot.

A detective working an unrelated incident at a North Fort Myers Walmart noticed a person matching the suspect's description. An image from the Walmart surveillance video was presented to the victim and his daughter, along with 11 other photos, all showing individuals with similar descriptions to the suspect. Both positively identified Trammell as the suspect.

Trammell was located with puncture wounds on the inside of his arms that were still bleeding. He was arrested and charged with robbery by sudden snatching.
