UPDATE: The Indiana State Police report they've been requested to investigate after a police pursuit involving the Elkhart County Sheriff’s Office which ended in a crash Tuesday.

The report states the deputy was in uniform at the time of his off-duty job. 

Authorities say the deputy confronted the suspect in the parking lot around 12:13 p.m., Tuesday.

Police say the suspect didn't stop when requested and quickly got into her vehicle, a beige 2012 Buick SUV.
