TLDR
Massachusetts prosecutors have charged 18-year-old Anthony DeMayo with murdering Danvers resident Janet Swallow, 68, in what investigators currently describe as a random attack. He has pleaded not guilty, is being held without bail, and is undergoing further court-ordered evaluation.
The killing of a 68-year-old woman inside her Danvers, Massachusetts, home has rattled a North Shore community and raised questions about how authorities characterize violence as random. Prosecutors say an 18-year-old high school senior they encountered miles away with a knife is responsible.
The case is in its earliest stages, with investigators still reconstructing what happened and why. Court records and officials’ statements show a fast-moving sequence that began with a 911 call about a man with a knife in Lynn and ended with a homicide investigation in Danvers and a murder charge in Salem District Court.
Reported Sequence of Events
According to Fox News, the investigation began when Lynn police received a 911 call about a man walking along Standish Road carrying a knife. Essex County District Attorney Paul Tucker said officers who responded found a man, later identified as DeMayo, behaving erratically and holding a knife with reddish-brown stains that appeared consistent with blood.
Police brought DeMayo to Salem Hospital for evaluation, while Lynn officers and Massachusetts State Police obtained and executed a search warrant at his home in Lynn. Tucker said evidence recovered there led investigators to notify Danvers police, who carried out a well-being check at a single-family home on Amherst Street and found longtime resident Janet Swallow dead with wounds consistent with homicide.
Randomness, Relationship, and Community Impact

At a news conference, Tucker told reporters, according to Fox News, that investigators do not currently believe there was a prior relationship between the accused teenager and the victim. He said, “What we can say and what we believe at this point is this was random. There was no connection between the defendant and the resident who was the victim here, Ms. Swallow.” Danvers Police Chief James Lovell publicly described Swallow as a longtime town resident and said her family had been notified.

Authorities have emphasized that, based on the information they have now, there is no ongoing threat to the public, and investigators believe DeMayo acted alone. Tucker later said the death was a tragedy that affected the Swallow family, the town of Danvers, and the Bishop Fenwick High School community in nearby Peabody, where officials say DeMayo is a senior.
Court Proceedings and Next Steps
According to NBC10 Boston, DeMayo was arraigned in Salem District Court, where he pleaded not guilty to a murder charge and was ordered held without bail. A court psychologist reported that DeMayo showed depressive symptoms, and the judge ordered him sent to Bridgewater State Hospital for further evaluation, with a pretrial hearing set for April 1st; his attorney did not object.
The murder charge is an allegation at this stage, and DeMayo is presumed innocent unless and until prosecutors prove the case beyond a reasonable doubt. Investigators from Lynn, Danvers, and the Massachusetts State Police continue to examine physical evidence and witness accounts, while prosecutors prepare for the next hearing and any future indictments in Superior Court.
The Danvers case sits at the intersection of public safety fears and the slow pace of the courts. As investigators continue their work, the details that emerge will test early claims that the killing was random and will shape both potential penalties for the defendant and the community’s understanding of what happened.
