KALISPELL, Mont. -

Detectives and local police have been working on the crime scene since around nine this morning and expect to be gathering evidence until late tonight. Kalispell police have also involved the local FBI field office in the investigation because of the nature of Susan Cahill's work.

The clinic's receptionist reported finding the break in when she showed up to open it this morning.

The owner thinks someone broke in through the back door and then vandalized the clinic.

Police and crime analysts are collecting evidence from the scene to find the possible suspects. The owner and practicing physician assistant of the clinic, Susan Cahill just moved to this Kalispell office three weeks ago.

Police have not let her inside to see the damage but she says she's seen plenty.

"I did look in at the lab area, which is completely, completely destroyed. So, I know that everything in my office is destroyed," said Cahill.

This isn't the first time Susan Cahill has experienced such an attack. In 1993 an anti-abortion activist fire bombed the Kalispell clinic where she worked with Dr. Armstrong.

If you know any further information about the investigation, please call the Kalispell Police Department.
