A Nicaraguan man living illegally in Pittsburgh faces up to 20 years in prison after allegedly launching a violent attack on federal agents — ramming a law enforcement vehicle, trying to grab an officer’s gun and biting an agent — after a failed attempt to buy a gun.
A federal grand jury in Pittsburgh indicted 33-year-old Darwin Alexander g on Wednesday on a charge of assaulting a federal officer.
The investigation began when the Department of Homeland Security learned that Davila-Perez had tried to buy a gun from a local dealer. During that transaction, he allegedly claimed to be a U.S. citizen.
The sale was blocked after the dealer discovered he was a Nicaraguan national with no legal status in the U.S. Federal law prohibits those in the country illegally from possessing or purchasing guns.

On Dec. 17, 2025, U.S. Immigration and Customs Enforcement agents attempted to pull Davila-Perez over to take him into custody for immigration violations. When agents activated their emergency lights, Davila-Perez didn’t pull over and fought back, according to authorities.
According to the indictment, Davila-Perez slammed his car into reverse, hitting an occupied law enforcement vehicle before jumping out to run.

During the ensuing struggle, he allegedly elbowed one officer in the face, tried to pull an agent’s service weapon from its holster, bit an officer’s arm and struck an agent in the forehead with a pair of handcuffs.
The whole time officers shouted commands in both English and Spanish for Davila-Perez to stop and show his hands. However, authorities say he ignored those orders until he was eventually subdued.
