Minnesota police responding Saturday to a 911 call about a van parked in front of a Walmart entrance discovered a man “performing an oral sex act” upon his wife, who was reclining in the driver’s seat.

When a patrolman approached the running vehicle around 9:15 PM, he spotted Shantell Nei, 32, “laid back in her seat with her pants down and exposed from the waist down."

The van, police noted, was situated in front of the main entrance of the Walmart Supercenter in Mankato (seen below), which is open 24 hours a day.

The van’s other occupant, Frank Nei, 32, “was also exposed with his shorts down to his knees.” Nei, Officer Steve Hoppe reported, had “leaned over across the center of the vehicle” and was “performing an oral sex act upon Shantell Nei.”
