BOZEMAN - A woman who allegedly stole a car at gunpoint in Helena and led police on a chase that reached speeds of more than 100 mph made her initial court appearance on Wednesday.
Lt. Corey Bailey of the Helena Police Department says that at about 3:15 p.m. on Tuesday, police officers were dispatched to the area of Alice Street and Runkle Parkway for a report of a person who had just stolen a vehicle at gunpoint.
The person - later identified as Sidney Aimsback - then drove away in the vehicle toward Broadwater County.
The vehicle was later spotted by Broadwater County Sheriff's deputies and was involved in a chase.
The chase continued through Broadwater County and into Gallatin County with several law enforcement agencies involved.
The woman headed south before coming to a stop and then barricaded herself in the vehicle. Because she was armed, law enforcement negotiated her capture which took approximately 20 minutes.
She is now behind bars at the Gallatin County Detention Center and is being held on $100,000 bond.
The Helena Police Department says that in addition to pending charges for Tuesday's incident, Aimsback is also being held on a probation violation, robbery, and theft from the Helena Police Department's jurisdiction.
According to the Montana Department of Corrections, Aimsback has a conviction in Cascade County for robbery.
Gallatin County Sheriff Brian Gootkin addressed the high-speed chase on Tuesday; he noted, "If that person is running from us our initial thought is, that person did something bad or is going to do something bad."
Officers knew that Aimsback was armed, and that was one of the main reasons the agencies decided to give chase, and also why deputies continued the chase through a populated area like Three Forks.
