Bexar County deputies are asking for the public's help finding 25-year-old Julian Henry Martinez Jr., who they say is on the run after removing a court-ordered GPS ankle monitor. Authorities allege Martinez assaulted his ex-partner on Monday and is now hiding his whereabouts while awaiting trial on multiple family-violence charges. The sheriff's office posted a public wanted notice and is urging residents to share any credible tips.

 

According to a Monday Facebook post by the Bexar County Sheriff's Office, Martinez, born Aug. 9, 2000, is described as a white male about 6 ft 1 in tall and 230 pounds, with brown hair and brown eyes. The post states he is on federal probation, removed his court-ordered GPS ankle monitor and may be driving a gray Buick, a gray Mustang or a black Fiat with front-end damage. Anyone with information was asked to call (210) 335-6000.

Charges and warrants

"WANTED PERSON- PLEASE SHARE," the Facebook notice reads. It lists Martinez as awaiting trial on stalking, continuous violence against the family and unlawful restraint. The sheriff's office also says two active warrants allege assault of a family or household member, impeding breath or circulation, and terroristic threat of a family or household member. He is suspected of assaulting his ex-partner on Monday, according to the Bexar County Sheriff's Office.

How to help and safety note

Deputies are clear on one point: if you see Martinez, do not approach him. Call 911 immediately if he poses an immediate threat. Otherwise, contact the Bexar County Sheriff's Office tip line at (210) 335-6000 with any information. Officials are asking people to share location details or photos only when it is safe to do so.

Why GPS removal matters

GPS ankle monitors send alerts when they are tampered with or removed, and supervising officers are expected to investigate those alerts quickly. The federal courts say that kind of electronic monitoring helps probation and pretrial services officers locate and respond to violations, according to the U.S. Courts. In Texas, a series of high-profile cases has fueled debate over whether cutting off an ankle monitor should bring tougher penalties, the Dallas Morning News reported.

The sheriff's office says the search for Martinez is active. This story will be updated if officials release more details.
