A 13-year-old New Mexico boy was arrested for allegedly driving a car while intoxicated Thursday when police discovered he wasn't alone.
In the back seat, Santa Fe County Sheriff's officials say was the boy's intoxicated grandmother.
According to an incident report, deputies pulled over a blue 1994 Oldsmobile after midnight, saying the driver was exhibiting suspicious behavior.
When he pulled over, police say the boy jumped into the back seat as deputies approached. The boy was taken from the vehicle and into a cruiser.
Meanwhile, his grandmother, 52-year-old Sanjuana Mercado-Mendez, was "highly intoxicated and very uncooperative," the report says.
"Sanjuana had a blank stare on her face and was unable to comply with my verbal commands, even in Spanish," the officer wrote in the report.
During their investigation, police say they ascertained the boy had consumed beer, which they allegedly found on the floor of the car.
The boy had no license and police say he blew a .14 on a portable breathalyzer.
The boy was first taken to hospital for medical clearance due to his level of intoxication, cops say. He was then taken to a juvenile detention center.
His grandmother was charged with suspicion of contributing to the delinquency of a minor, child abuse and possession of an open container of alcohol in a motor vehicle.
Mercado-Mendez is due to appear in court for a preliminary hearing on August 31.
