Auburn Police arrested four people — including three juvenile males and one adult female — on Tuesday, April 15, 2025, following an armed robbery at the Haggen Grocery Store and a high-risk vehicle stop that uncovered multiple modified firearms.

Officers responded around 4 p.m. after a store employee reported being threatened with a gun during a shoplifting incident.

The suspects fled in a blue Audi A4, which was tracked using city traffic cameras.

Police located the vehicle near Lakeland Hills Way SE and used a Precision Immobilization Technique (PIT) maneuver to bring it to a stop.

All occupants were arrested without injury.

Authorities later learned a child was also in the car; the child was safely released to a family member.

One juvenile was carrying three handguns — one of them stolen — all modified with switches to make them fully automatic and equipped with extended magazines.

All four suspects were booked on probable cause for first-degree robbery. Additional charges include unlawful possession of a firearm and possession of a stolen firearm. The juveniles were transported to Remann Hall Juvenile Detention Center; the adult was booked into the Pierce County Jail.

“This case is currently under review by Auburn Police Department detectives,” the department said. “Excellent teamwork and a job well done by all of those involved.”
