The Essex County District Attorney’s Office and multiple outlets described the attack as a random act and said Swallow was found dead at her 17 Amherst St. residence.

Police encounter details

Multiple witnesses and 911 callers reported seeing DeMayo walking in Lynn with a knife and erratic behavior shortly after a crash, which prompted police response and his subsequent detention.

Witness accounts include a description of him holding a large knife and acting 'unhinged,' and police radio transmissions place an earlier car crash near the time he was observed walking through neighborhoods.

Officers who encountered him sought medical attention for a psychiatric evaluation as they took him into custody.

Evidence and alleged crime

Investigators say physical evidence recovered from DeMayo’s Lynn residence and data from his phone linked him to Swallow’s home, where officers found her dead with wounds consistent with homicide;

Prosecutors said clothing with stains consistent with blood and undisclosed phone evidence pointed them to 17 Amherst St.

They reported that DeMayo apparently entered Swallow’s home by climbing through a window and stabbed her while she was in bed, and authorities have said they do not believe anything was taken from the home.

Mental health and court

Court testimony and a forensic psychologist’s evaluation prompted a judge to order DeMayo to be held without bail and sent to Bridgewater State Hospital for a 20-day psychiatric evaluation to assess his competency and criminal responsibility.

In a roughly one-hour interview, psychologist Joyce Perrotta said DeMayo showed depressive symptoms — including restricted affect, anhedonia and suicidal ideation — and while he demonstrated 'adequate factual understanding' of proceedings, there were concerns about his rational understanding and legal decision-making capacity.
