As officers watched the vehicle, three people came out of the Walmart and entered it. All three were taken into custody.

The female driver and two males were taken to the Broomfield jail, according to BPD spokesperson Jolene Reefe. There, one of the three notified investigators of a potentially dangerous device still inside the car.

Investigators then radioed officers at the Walmart and instructed them to stop examining the vehicle.

The bomb squad was then called in.

The device was “disassembled,” said Reefe.

Reefe said one of the three suspects, Zach Rickard, had shoplifted from the Walmart. John Ulibarria was arrested on outstanding warrants, she said, and Heather Moore was identified as the driver of the stolen vehicle.

Broomfield PD says the vehicle, a white Suzuki Vitara, was reported stolen out of Thornton last Wednesday.
