U.S. Marshals are asking for the public's help finding a 41-year-old woman wanted on an active federal warrant. Jennifer Rivera, whose last known address is in the unincorporated community of Adkins, allegedly violated the conditions of her supervised release stemming from a 2019 conviction for financial institution fraud.
What Led to the Warrant
According to KABB, Rivera was sentenced to 240 days in custody followed by three years of supervised release after her fraud conviction, per the U.S. Marshals Lone Star Fugitive Task Force. Authorities say she tested positive for methamphetamine twice and failed to appear for five required drug tests, despite having been enrolled in substance abuse treatment. For defendants whose supervised-release conditions require drug testing, federal law requires an initial test within 15 days of release and at least two more afterward unless a court waives the requirement, according to the Legal Information Institute.
That testing requirement is not optional. Under 18 U.S.C. § 3583(g), a court must revoke supervised release and order a defendant back into custody if the person refuses a drug test or tests positive for illegal drug use on more than three occasions in a single year, according to the Office of the Law Revision Counsel. Those revocation proceedings run on a lower, preponderance-of-the-evidence standard rather than the standard used in a criminal trial. U.S. Marshals are seeking Rivera under an active federal warrant.
Searching Near Adkins
Rivera's last known address places her in Adkins, an unincorporated community about 14 miles east of downtown San Antonio along Farm to Market Road 1518 and Loop 1604 in eastern Bexar County, according to the Texas State Historical Association. Investigators say Rivera may have altered her appearance since the warrant was issued.
Marshals describe Rivera as 5 feet 8 inches tall and weighing about 200 pounds, with brown hair and blue eyes. She has several identifying tattoos: a sun on her left hand, the name Richard on her right arm, a flower on her chest, and a Mickey Mouse design on her right thigh.
A Task Force With a Wide Reach
The Lone Star Fugitive Task Force is a joint operation pairing U.S. Marshals with officers from the Bexar County Sheriff's Office and the San Antonio Police Department. Hoodline previously detailed the task force's local work after marshals found two missing children in a suspect's car outside a Southtown taco spot in August.
The task force itself has deep roots in Texas law enforcement. Established in March 2005, it covers an 8-division jurisdiction spanning 93,000 square miles, 68 counties, and 809 miles of the U.S.–Mexico border, with division headquarters in San Antonio, Austin, El Paso, Waco, Del Rio, Midland, Pecos, and Alpine, per the U.S. Marshals Service. Between its founding and mid-2025, the task force investigated and apprehended nearly 59,000 fugitives across Western Texas, including 1,795 people wanted for murder.
Technical Violations, Not New Charges
Rivera's case underscores a distinction that can get lost in headlines about federal manhunts: a revocation warrant is not a new criminal charge. It reflects an alleged failure to comply with the terms of a prior sentence, not an accusation of a new crime. Nationally, technical violations — non-crime infractions like failed drug tests or missed check-ins — accounted for 13% of all closed federal post-conviction supervision cases, according to a study by the Administrative Office of the U.S. Courts. Roughly 5% of closed federal supervision cases resulted in incarceration sentences of more than six months specifically for technical violations.
If Rivera is captured, she would face a judicial revocation hearing where a judge could order her back into federal custody, though the specific sentence prosecutors will seek has not been disclosed.
How to Help
U.S. Marshals are asking anyone with information on Rivera's whereabouts to call 210-657-8500.
