HOUSTON — A jury on March 6 convicted a former U.S. Border Patrol agent of threatening a federal official.

The jury convicted former Border Patrol Agent Daniel Polanco, 38, of Edinburg of threatening Homeland Security Investigations Special Agent Isidro Martinez after a court hearing in Houston on Oct. 3.

Homeland Security Investigations, a division of U.S. Immigration and Customs Enforcement, investigated Polanco and other law enforcement officers accused of working with drug traffickers.

Polanco pleaded not guilty to drug trafficking charges. A jury, however, found him guilty in July.

Polanco returned to court in October, when his lawyers requested a new trial. U.S. District Judge Keith P. Ellison denied the request.

As he left the courtroom, Polanco stopped, pointed at Martinez and said: “This is gonna come back to you m-----f-----. You’ll see,” according to the criminal complaint against him.

Martinez reported the comment, which resulted in a new indictment against Polanco for threatening a federal official.

Polanco pleaded not guilty. After a two-day trial, a jury convicted him on March 6.

Both trials took place at the federal courthouse in Houston.

Polanco faces a maximum of six years in prison on the threat charge and 10 years to life in prison on the drug trafficking charges.

Sentencing in the drug trafficking case is scheduled for April 9. Sentencing in the threat case is scheduled for May 22.

The U.S. Attorney’s Office for the Southern District of Texas declined to comment on Polanco’s conviction in the threat case. His attorney didn’t respond to a request for comment.
