Two suspected members of the Tren de Aragua gang, Dixon Azuaje-Perez, 20, and Nixon Azuaje-Perez, 19, were released from custody in Aurora, Colorado, after being tied to a July 28 shooting, according to the New York Post. Despite being accused of tampering with evidence, the brothers posted a $1,000 bond and were fitted with GPS monitors.

Police confirmed several men were arrested in connection to the shooting, which left two men injured. One of the suspects, Jhonnarty Dejesus Pacheco-Chirinos, a documented Tren de Aragua member, remains in ICE custody. However, local authorities released the Azuaje-Perez brothers despite Immigration and Customs Enforcement (ICE) placing detainer requests.

The brothers reportedly entered the U.S. via the Biden-Harris administration’s CBP One app, used for asylum appointments. Law enforcement agencies have noted an increase in Tren de Aragua activity in Colorado, linking the gang to several apartment takeovers in Aurora.
