Rosamond, California - Pepperoni, Canadian bacon, sausage, and a semiautomatic handgun – that's what cops found in a pizza box during a routine traffic stop in California on Tuesday morning.

The fully loaded pizza discovered by Kern County Sheriff's deputies led to the arrest of four people early during a traffic stop near Rosamond High School, some 80 miles north of Los Angeles.

Deputies found a pizza box among a stash of methamphetamine, Xanax, fentanyl and cocaine recovered at the scene. When deputies popped open the delivery container, they spotted a loaded gun sitting atop an uneaten pie.

Deputies initially pulled over 47-year-old Danny Carson at 3 AM for driving a vehicle without its headlights turned on in a residential neighborhood, sheriff's officials said.

Carson had a misdemeanor warrant and was on parole for a previous weapons violation, according to deputies.

Deputies searched his car and also found an additional loaded handgun, a sawed-off shotgun, more than $1,000 in cash, scales, narcotic paraphernalia and packaging, sheriff's officials said.

Carson was arrested along with three passengers in his vehicle: 47-year-old Benjamin Vasquez, 30-year-old Krista Rutledge, and 18-year-old Saydee Vandehey.

All four were charged with a variety of counts, including conspiracy to commit a crime, transportation of narcotics, concealment of a weapon in a vehicle, possession of cocaine for sale, and felony possession of ammunition, according to deputies.

The four were booked into the Kern County-Lerdo Justice Facility in Bakersfield.
