Anaconda Police are asking for help finding 41 year old Tammy Salle.
Detectives tell NBC Montana they've located the car Salle was believed to be driving.
The 2008 Pontiac Grand Prix was located at the Racetrack Exit off I-90. We're told it had a flat tire and there were footprints around the vehicle.
Salle was last seen Sunday morning December 23. According to Anaconda Police Chief Tim Barkell her adult daughter reported her missing the day after Christmas.
She is described as 5'5" with brown hair and green eyes and weighs between 140 and 150 pounds.
Police have questioned her live in boyfriend who says the two got into and argument and Salle took off. They say he was emotional, and they haven't been able to locate him since the initial questioning.
If you have any information please contact the Anaconda Police Department at 563-5421.
