A missing 17-year-old autistic boy in Cypress and a woman who never returned from a walk at Jesse H. Jones Park in Humble were both found safe on Sunday, thanks to the same scent-tracking dog working two separate calls hours apart. Deputies with Constable Mark Herman's office responded to Tigris Lane in the Cypress area to search for the teen, while another team of deputies searched for the missing woman near the park in Humble.
K-9 Hades, a Hanoverian and Plott Hound trained in scent-discrimination tracking, located both the teen and the woman, according to KPRC Click2Houston. The woman was found in good condition and taken by deputies to Pundt Park, where she was reunited with her group. Constable Herman called it “another safe ending thanks to the hard work of our deputies and K-9 Hades,” adding that “their dedication to finding missing members of our community is truly remarkable.”
A Dog Built for This Exact Job
Hades trained at the Georgia K9 National Training Center specifically to locate missing individuals with autism, Alzheimer's, and dementia, according to a Facebook post from Constable Mark Herman's Harris County Precinct 4 office. The dog works under handler Deputy Daniela Palacios as part of a specialized search unit, and Precinct 4 also fields a second scent-discrimination dog, K-9 Sig, a Plott Hound tasked with human scent tracking across long distances and difficult terrain, per the same Facebook post. In April, Hades tracked and located a missing child hidden in a dense Harris County wooded area within 10 minutes of deployment alongside drone support, Officer Magazine reported.
The distance between where the woman went missing and where she turned up helps explain why the search stretched across two locations. Jesse H. Jones Park in Humble and Pundt Park in Spring are connected by the Spring Creek Greenway, a continuous paved multi-use trail network stretching more than 12 miles along Spring Creek in northern Harris County, according to TrailLink. That connected trail system links several regional parks along the natural floodplain, giving a missing park visitor on foot a direct route between the two sites.
Why Elopement Calls Move Fast
Sunday's search for the autistic teen carried the same urgency that shapes every missing-person call involving autism. Nearly 50% of children with autism spectrum disorder engage in wandering or elopement behaviors from safe settings, and accidental drowning causes over 70% of fatal outcomes in those cases, according to the National Autism Association. A 2017 Columbia University Mailman School of Public Health study found that children diagnosed with autism face an accidental drowning risk 160 times higher than the general pediatric population, the association notes, since autistic individuals are often drawn to water for sensory stimulation.
That risk isn't theoretical in Harris County. In September 2024, Hoodline covered how a search for a missing autistic 5-year-old in Cypress ended in tragedy when the boy was found deceased in a retention pond. Just two days before Sunday's dual searches, Hoodline also reported on a separate case out of Spring, where K-9 Hades and Deputy Daniela Palacios joined the hunt for a missing autistic 12-year-old boy.
A Constable's Office Built for Scale
Constable Mark Herman's Precinct 4 is the largest constable agency in the United States, employing more than 670 sworn personnel across a 500-square-mile jurisdiction serving over 1.2 million residents in north Harris County, according to Houston Landing. That scale matters given the volume of cases the region generates: Harris County law enforcement agencies logged 6,357 missing child reports in 2025, more than 20% of all juvenile missing person entries recorded statewide, per Texas Center for the Missing data.
Under Texas Department of Public Safety regulations, law enforcement can request an Endangered Missing Persons Alert once a missing person's diagnosis of an intellectual disability or pervasive developmental disorder, including autism spectrum disorder, is verified by officers. It remains unclear how long either the teen or the woman had been missing before deputies were alerted Sunday, or whether any locative technology or park boundary safeguards played a role in either recovery. For now, both cases closed the way Precinct 4 deputies hope every one of these calls will end — with a reunion instead of a tragedy.
