Sanchez-Cruz is facing charges that include hit-and-run, serious injury by motor vehicle, reckless driving and open container, police said. Additionally, Channel 2 reported, immigration officials have a warrant for his deportation.
The man's brother Milton Sanchez, the registered owner of the vehicle, filed a police report about 30 minutes after the accident alleging that his vehicle had been stolen, police said.
"There was some covering up of who was driving," Investigator David Hammack of the Gwinnett County Police Department told Channel 2.
Hammack also said that beer containers and an open bottle of gin -- along with a lime and a shot glass -- were found in the vehicle.
Sanchez-Cruz's brothers were arrested for their roles in a cover-up, police said.
Milton Sanchez, 32, of Norcross is charged with filing a false report of a crime and obstruction; Freddy Sanchez-Cruz, 24, also of Norcross, is charged with obstruction and providing a false date of birth to law enforcement; and Orlando Sanchez, 38, whose city of residence was not available, is charged with obstruction, authorities said.
