He's being held without bail at Bridgewater State Hospital pending a mental evaluation. Probable cause hearing set for April 1. District Attorney Paul Tucker: "This is just a very difficult case because of the randomness of this violence."
The victim was a beloved ICU nurse at Lahey Hospital in Burlington and a mother of two. DeMayo is a senior at Bishop Fenwick High School — a private Catholic school now offering counseling to students. He pleaded not guilty to murder and home invasion charges.
When police arrived, he allegedly confessed on the spot: "I killed a woman last night." Officers found bloodstained clothing at his home and cell phone data that led them to Swallow's house, where she was discovered with multiple stab wounds.
After the killing, DeMayo drove 10 miles home to Lynn. But the next day, he returned to the victim's neighborhood and was spotted waving a 6-inch blade, stabbing bushes like he was "practicing" on a person. Neighbors called 911 in terror.
The attack was completely random. DeMayo drove around nearby communities Wednesday night before stopping at Swallow's home, smashing through a window, and stabbing the sleeping nurse in the neck. The two had never met — no robbery motive, just premeditated murder.
18-year-old Anthony DeMayo broke into a stranger's home in Danvers, MA and stabbed 68-year-old ICU nurse Janet Swallow to death while she slept. His confession to police: "I had been planning on committing this act for a long time, and wanted to kill someone for a long time."
