An 84-year-old Malden woman with Alzheimer's and depression who went missing from the city's east side Friday evening has been found safe, police announced early Saturday. Mary McNally, described as 5 feet 5 inches tall and about 120 pounds with strawberry blonde hair and brown eyes, had last been seen wearing a black-and-white striped shirt with black pants.
According to the Malden Police Department, McNally was reported missing Friday evening and assigned incident number 26003460 as officers worked to locate her. The department thanked everyone who shared the bulletin and assisted in the search, and had asked community members to remain alert and contact police with any information about her whereabouts. Police had listed two contact numbers for tips, 781-322-1212 and 781-397-7181, and McNally's case carried NIC number M2690012644.
The scare unfolded in a city of roughly 66,000 residents packed into just 5 square miles, giving Malden one of the higher population densities in the region at more than 13,000 people per square mile, per U.S. Census Bureau estimates. That density can complicate a physical search for someone on foot, though it also means more potential witnesses circulating nearby who might spot a missing person and call it in.
Why Dementia-Related Disappearances Demand Fast Action
Cases like McNally's carry real urgency. The Alzheimer's Association has found that 60% of people living with dementia will wander at least once, and medical research cited by the Cleveland Clinic shows that up to half of missing dementia patients not found within 24 hours suffer severe injury or death. Nationally, more than 7 million Americans live with Alzheimer's disease, with symptoms that often combine memory failure, depression, disorientation, and unannounced wandering, according to the Alzheimer's Association's 2026 data.
Clinical researchers at Hebrew SeniorLife note that so-called critical wandering, or elopement, among seniors with dementia often happens during routine daily transitions, which is why rapid public notice in the first few hours is considered vital to a safe recovery. That urgency is baked into Massachusetts law: under General Law Chapter 6A, Section 18L, the state's Silver Alert Community Response System requires coordinated search responses among state and local public safety agencies whenever an adult with serious cognitive impairment like Alzheimer's or dementia is reported missing.
Tools Police Have at Their Disposal
Beyond direct phone lines, the Malden Police Department also runs a TIP411 text service that lets residents submit anonymous tips during active investigations by texting the keyword MALDEN to 847411. Research published in the Journal of the American Academy of Psychiatry and the Law notes that Silver Alert systems frequently rely on automated Reverse 911 calls to immediately notify residents near a missing person's last known location, a tool designed to turn nearby neighbors into active observers within minutes.
Families of people with dementia also have a preventive option available well before a crisis hits. Since 2015, Massachusetts elder care and public safety agencies have offered local pre-registration registries that let families submit photos and medical profiles to police in advance, aiming to eliminate search delays if a loved one ever goes missing. Separately, state lawmakers have introduced House Bill H2657 to create a Purple Alert framework, which would let police issue rapid, broad-scale emergency notifications for missing individuals with cognitive, developmental, or physical disabilities alongside the existing Silver Alert system.
It is not the first time Malden police have turned to the public for help finding a vulnerable resident. Hoodline previously reported on the search for missing teen Aline Santos earlier this year, and on a 2024 appeal for help locating Ian Umansky. In McNally's case, the outcome was the one families hope for: police confirmed she was located and is safe, closing out a search that began Friday evening on Malden's east side.
