A statewide Silver Alert is underway for 72-year-old William Clark, who vanished from a house on Johnson Street in New Orleans and was last seen on Sunday, August 31. Clark is believed to be on foot, traveling in an unknown direction, and his family has told authorities he has a medical condition that may impair his judgment.
Louisiana State Police issued the alert on behalf of the New Orleans Police Department after logging the request at 3:24 a.m. Tuesday, according to WDSU. State troopers describe Clark as a Black male standing 6 feet 1 inch tall, weighing about 185 pounds, with brown eyes and short grey hair, per an alert bulletin from Louisiana State Police. He was last seen wearing a yellow shirt with red stripes and green jeans.
Anyone with information on Clark's whereabouts is asked to call the New Orleans Police Department at 504-821-2222 or dial 911, the report notes.
Why Statewide Alerts Require Strict Criteria
Not every missing-adult case triggers a statewide broadcast. Under the Louisiana Silver Alert Act, state law reserves these alerts for senior citizens 60 or older, or adults with documented cognitive impairments, whose disappearance poses a credible safety threat, according to the Louisiana State Legislature. Local agencies like NOPD must submit verified case details and photos to the Louisiana State Police Fusion Center hotline, which then coordinates dissemination across law enforcement, news media, and digital highway messaging boards statewide.
New Orleans also maintains its own layer of response for vulnerable missing residents. Under NOPD Chapter 41.23, the city can pair state coordination with localized tools such as Bryan's Call notifications, Ring app alerts, and digital billboard notices, according to the City of New Orleans. It remains an open question whether those city-level tools have been activated to support ground searches near Clark's Johnson Street home, which sits within the urban corridors stretching through the Mid-City historic district and Esplanade Ridge.
The Clock Matters for Wandering Adults
The family's report of a condition that may impair judgment adds urgency to the search. Clinical data cited by the Cleveland Clinic shows roughly 60% of people living with dementia or similar cognitive conditions will wander at least once during their illness, and the same research indicates that half of those who wander and aren't located within 24 hours suffer severe injury or death. Search-and-rescue statistics cited by the City of Wheaton's social services office suggest that 94% of missing individuals with dementia who wander on foot are found within 1.5 miles of where they were last seen, offering a rough radius for search efforts around Johnson Street.
Disorientation can also put missing individuals in immediate danger. A study published through the Journal of the American Academy of Psychiatry and the Law and cited by USF Health found that 15% of people recovered during Silver Alert activations were located in life-threatening situations, including standing on active railroad tracks or walking in roadway lanes.
A Pattern of Recent Silver Alerts in Louisiana
Clark's case follows a string of recent Silver Alerts across the state. Hoodline covered a Baton Rouge alert for Chester Baggett earlier this month, and in January, an 84-year-old New Orleans man named Malcolm Flot was found safe after a similar statewide alert. Not every missing-adult case in the city rises to that level, either — a Lower Ninth Ward family's search for 22-year-old Kemon Terrell last month illustrated how NOPD's Chapter 41.23 protocols apply differently when age or documented impairment isn't part of the picture.
For now, Clark's family and NOPD are asking the public to stay alert for a man matching his description, last seen in yellow-and-red striped clothing and green jeans, and to call authorities immediately with any sightings.
