Alaska FBI agent named new special agent in charge in Salt Lake

The FBI has appointed a woman with nearly three decades of agency experience to oversee operations in Utah, Idaho, and Montana.

Mary Frances Rook was named special agent in charge in Salt Lake City after recently holding the same title in the Anchorage, Alaska division.

Rook started with the FBI as a lab technician in 1984. She’s worked in several posts, including assistant special agent in charge roles in Salt Lake City and in Helena, Mont.

FBI officials say that in her most recent role in Alaska, she oversaw several high-profile investigations, including the prosecution of extremists plotting to murder state and federal law enforcement officials and a federal judge and his family.

Rook is a native of Montana and has a bachelor’s degree in zoology from Colorado State University.
