A 17-year-old with autism has been missing from West Park since the early morning hours of Friday, and detectives are asking the public for help finding him before stormy South Florida weather complicates the search. Alyjah Allen was last seen around 2 a.m. near the 3600 block of Southwest 46th Avenue, wearing a long white sleeve shirt, gray pants and white shoes.
According to the Broward Sheriff's Office, Allen's family reports that he has autism and is high functioning. He is described as about 5 feet 9 inches tall and roughly 130 pounds, with brown eyes and distinctive multicolored blue, black and blonde hair. Missing Persons detectives with the Broward Sheriff's Office, which handles law enforcement duties for West Park under a municipal contract rather than through an independent city police department, are leading the search, according to Florida Bulldog.
Anyone with information is asked to contact BSO Detective Chris Blankenship at 954-321-4268, or to text 911. The sheriff's office also maintains a non-emergency line at 954-764-HELP (4357) for residents who want to report tips outside of an active emergency.
Stormy Weather Adds Urgency to the Search
The timing of Allen's disappearance comes as South Florida braces for steamy temperatures and heavy rainstorms forecast through the weekend. WSVN 7News reported on the search alongside those regional weather updates, noting the stormy conditions expected across the region from Friday through Sunday, as detailed by WSVN 7News. Rain and reduced visibility can make outdoor searches more difficult and increase physical hazards for anyone missing outdoors for an extended period.
The stakes around wandering behavior in autistic youth are well documented nationally. Data summarized by the U.S. Department of Health and Human Services and research published in Pediatrics indicates that roughly 49% of children with autism attempt to wander or elope from safe environments after age four, according to HHS.gov. The National Autism Association has found that accidental drowning accounts for more than 70% of lethal outcomes in autism-related wandering cases, with autistic children facing a drowning risk 160 times higher than the general pediatric population, per the same research.
Florida's Alert Systems for Missing Autistic Residents
Florida's alert landscape includes multiple pathways depending on age. The state's Purple Alert system, established by the legislature in 2021, is designated specifically for missing adults 18 and older who suffer from cognitive, intellectual or developmental disabilities, according to the Florida Department of Law Enforcement. Because Allen is 17, his case would instead fall under frameworks for missing minors, including the Florida Spectrum Alert that FDLE officially launched in June, a system built to rapidly broadcast alerts when a missing child under 18 is reasonably believed to have autism spectrum disorder and be in danger.
That state-level effort has since been echoed at the federal level. In August, the U.S. Department of Health and Human Services, alongside the Department of Justice and FEMA, launched a national initiative aimed at leveraging existing Missing and Endangered Person alert frameworks to streamline emergency notifications when autistic individuals go missing, per HHS.gov. Separately, federal protections under Suzanne's Law require law enforcement agencies to treat missing young adults aged 18 to 20 with the same urgent reporting priority and immediate entry into the National Crime Information Center database as missing juveniles, according to the Cocoa Beach Police Department.
BSO's Recent Track Record With Missing Juveniles
The Broward Sheriff's Office Missing Persons Unit has recently closed out other high-profile juvenile cases. Earlier this month, detectives located 16-year-old Keyonnie Archibald safe in Broward County following a two-month search. As with that case, BSO's standard protocol is to publicly announce when a missing juvenile has been located safely while withholding specific details about the recovery location, custody status, or underlying reasons for the disappearance, a practice the unit has followed consistently while balancing public assistance requests with privacy protections for minors.
For now, Allen remains missing, and detectives are continuing to ask anyone in the West Park area or with any information to come forward. The sheriff's office has emphasized that tips can be called in directly to Detective Blankenship, texted to 911, or routed through its non-emergency line as the search continues.
