Overview
- Anthony DeMayo, 18, appeared by video for Essex Superior Court arraignment as the judge entered a not-guilty plea and ordered him held without bail.
- The judge approved prosecutors’ request for an independent exam to assess competency while DeMayo remains at Bridgewater State Hospital.
- A Salem District Court judge previously found him incompetent to stand trial and committed him for treatment, with a status hearing set for May 29.
- Police say Lynn officers found DeMayo carrying a blood-stained knife and used his phone data to help locate Janet Swallow dead in her Danvers home.
- Prosecutors say the attack appears random, report no items missing from the home, and note there is no known link between the teen and the victim.
