Funeral services for 47-year old Sergeant Dwayne Polk will be held Saturday.
Polk was a 16-year veteran of the Harris County Sheriff's Office. He was killed in a crash early Sunday morning when 22-year old Andres Munos crashed into his vehicle.
Investigators say Munos' blood alcohol level was nearly twice the legal limit.
Munos was previously deported and has a prior DWI arrest. He's being held without bond.
