A Texas sheriff’s sergeant has died after being struck by a suspected intoxicated driver in a hit-and-run, authorities said early Monday.

Sgt. Ramon Gutierrez, 45, was conducting an off-duty motorcycle escort of a heavy load along a service road around 8900 East Sam Houston Parkway North near Tidwell Road just before 1 a.m., Harris County Sheriff Ed Gonzalez said

Gutierrez was off his motorcycle and blocking an exit ramp when a motorist drove around his bike and struck him, the sheriff said. The 40-year-old female driver fled the scene but was later stopped and arrested. Gonzalez said she showed signs of intoxication.

Gutierrez was airlifted in critical condition to Memorial Hermann Hospital, where he died.

The accused driver has been charged with intoxication assault of a police officer and failure to stop and render aid, according to authorities.

Gutierrez was a 20-year law enforcement veteran, serving for the last 13 years in the Vehicular Crimes Division of the Harris County Sheriff’s Office.

He is survived by his wife, daughter and two sons, Gonzalez said.
