A Silver Alert is active for 78-year-old Alvin Longgood of Largo, who was last seen in person around 9:30 P.M. Tuesday at Dunedin Lanes on Patricia Avenue before family lost contact with him hours later. Deputies now say he is driving a silver 2016 Ford F-150 pickup truck, correcting earlier social media reports that described a gray 2015 Ford Fusion.
According to an official news release from the Pinellas County Sheriff's Office, Longgood stands 5 feet 10 inches tall, weighs 130 pounds, and was last seen wearing a green shirt and green shorts. He lives at 11371 120th Terrace North in Largo; Dunedin Lanes is at 405 Patricia Avenue, where he was last physically spotted.
The timeline matters more than it might first appear. While Longgood was seen in person at the bowling alley around 9:30 P.M., deputies confirmed that family or associates were still in phone contact with him as late as 11:40 P.M. that same night — more than two hours later. That gap means investigators cannot simply focus search efforts around the bowling alley or his home address alone.
Silver Alert and Vehicle Information
Florida's Silver Alert system can include highway Dynamic Message Signs deployed by the Florida Department of Transportation. Longgood's vehicle is now described as a silver 2016 Ford F-150.
Separately, the Pinellas County Sheriff's Office uses license plate reader networks, including Flock Safety technology, to flag vehicles linked to missing and endangered people, as reported by the Tampa Bay Times. Sheriff Bob Gualtieri introduced stricter database access policies for that system in September 2026 following internal misuse investigations.
How Pinellas County Escalated the Search
Deputies formally entered Longgood into the Florida Crime Information Center database as a Missing/Endangered Adult, noting that he suffers from memory and medical issues. Under guidelines from the Florida Department of Law Enforcement, local agencies must confirm a credible threat, enter the person into FCIC, and broadcast a local Be-On-The-Lookout advisory before requesting a statewide Silver Alert — a process that requires descriptive vehicle details in order to activate highway message signs.
Florida's Silver Alert system applies to missing individuals at least 60 years old, or adults 18 to 59 who lack the capacity to consent, when law enforcement has verified irreversible cognitive decline such as dementia or Alzheimer's. The designation is distinct from Florida's Purple Alerts, which cover missing adults with a qualifying disability unrelated to substance abuse or dementia — a distinction Hoodline previously explored in depth.
A Senior Population That Raises the Stakes
Speed matters in cases like this because a disoriented driver may travel well beyond the immediate area.
That urgency is compounded by local demographics. More than 21% of Pinellas County's population is 65 or older, giving the county one of Florida's highest concentrations of older residents — a reality that makes Silver Alert response a recurring focus for local deputies. It is a dynamic Hoodline has tracked before, including in last month's search for a missing 99-year-old driver in St. Petersburg.
Anyone who spots Longgood or his silver 2016 Ford F-150 is urged to contact the Pinellas County Sheriff's Office.
