As part of his bond, Garzez must follow certain conditions including not traveling outside the Rio Grande Valley, he must wear an electronic monitoring device and must follow a home curfew.

Garzez was arrested after crashing into a vehicle on the shoulder lane, killing 46-year-old David Zapata.

Garzez allegedly fled from the crash scene but was located nearby and taken into custody.

According to a criminal complaint obtained by Channel 5 News, Garzez told law enforcement officers at the scene that he didn't stop when the crash happened because he was "scared."

The complaint said there was blood spatter on the passenger door of Garzez's vehicle. The complaint added that a small white baggy containing 1.26 grams of a white powdery substance was found in Garzez's vehicle.

Garzez also had "constricted pupils," leading the trooper to believe that Garzez was under the influence of narcotics, the complaint states.

"Garzez was eager to provide breath sample was hesitant to provide blood sample," the complaint said, adding that Garzez then consented to having his blood drawn.
