BUTTE, Mont. (AP) — Anaconda police searching for a 41-year-old woman missing since Sunday say they want to question her boyfriend again.

The Montana Standard reports Tammy Salle's family told police it is unusual for her to be gone for so long without making contact.

Salle's daughter reported her missing Wednesday. Police have questioned Salle's boyfriend, who told them he argued with her Sunday evening and she left in his vehicle.

Police found the car near Racetrack Friday.

Police Chief Tim Barkell says the disappearance appears suspicious and investigators are trying to locate the boyfriend again for further questioning.

Barkell says John Goldberg didn't show up as requested and has stopped answering his cellphone.

Salle is white, 5 feet 5 inches tall, 140 to 150 pounds with green eyes and brown hair.
