About 8 p.m., Anna arrived and pulled into the lot.

At this police time detectives boxed in the car and left their vehicles displaying badges and ordering operator to stop the vehicle. The operator then put the vehicle in reverse and backed car into the task force van. The passenger window was broken, and the operator was removed without incident.
