A Border Patrol agent who was mourned for having died “in the line of duty” reportedly succumbed to a COVID-19 related illness, as President Joe Biden has not imposed his vaccine mandates on illegal migrants intercepted at the border.

Anibal Perez was mourned from a previously held-private cause, but reports now say the Customs and Border Patrol supervisory agent has died from COVID-19 illness, according to KVOA-4 News in Tuscon, Arizona.

USBP Chief Raul Ortiz tweeted condolences to Perez earlier this month, calling the death “in the line of duty”:

“The entire USBP family mourns the loss of Supervisory Border Patrol Agent Anibal ‘Tony’ A. Perez who sadly passed away in the line of duty. Please keep his family, friends, and colleagues in your thoughts.”

Perez has served more than 15 years with Border Patrol, last as a supervisor in the Tuscon sector.

The death comes as the Biden administration has been under heavy scrutiny for their border policies and handcuffing agents.

“The agents feel completely abandoned by this administration,” retired agent Gil Maza told National Review in October. “They feel like there is nobody out there for them.”
