Montgomery County police are seeking information about Dianne McLeod Brown, whom the department’s 4th District Investigative Section described as 77 and last seen Friday, June 12, 2026, at 2 a.m. Police have not shared further details about the circumstances of her disappearance. The department’s public appeal asks for help locating her.
Brown is 5 feet 3 inches tall, with gray hair and brown eyes. She may be driving a black 2012 Honda CRV with Maryland plate 2AK6592. Anyone with information about her location is asked to call the Montgomery County Police Non-Emergency line at (301) 279-8000, described in the alert as a 24-hour line.
What a Silver Alert indicates
A Silver Alert is intended to notify public safety agencies and the public when an adult with cognitive impairment is missing and the disappearance poses a credible threat to the person’s health and safety, according to the Maryland Department of State Police. That describes the program’s general purpose; it does not establish additional details about Brown’s circumstances.
Other Montgomery County cases offer limited context
Two separately reported Montgomery County cases show how different Silver Alert searches can unfold, but they do not indicate a trend or predict an outcome in Brown’s case. Police said Judith Woodard, reported missing under a Silver Alert, was found safe and unharmed at Randolph Road and New Hampshire Avenue on March 29, 2026, after traveling through New York, New Jersey and Maryland, according to department records. In another notice, dated May 13, police reported that missing 79-year-old Charles Ray Jenkins of Gaithersburg had been located safe and unharmed, according to the county announcement. Neither case supplies information about what happened to Brown.
