A former federal employee indicted more than a year ago on multiple charges of sexual assaults in Anchorage has been indicted by an Anchorage grand jury on two more counts of sexual assault last week.

The FBI is seeking more information about his activities outside of Anchorage as the investigation into the allegations continues, said FBI spokesperson Chloe Martin.

Bert Christopher Heitstuman, 51, is currently indicted on charges of eight counts of felony second-degree sexual assault and one count of first-degree sexual assault.

Heitstuman is accused of abusing his position as a law enforcement officer and as a security officer in connection with all of the charges against him, according to the Alaska Department of Law. Heitstuman was a law enforcement specialist with the Department of Homeland Security Federal Protective Service, and six of the eight incidents are related to conduct alleged to have occurred while he was in that job.

Other incidents are alleged to have occurred while Heitstuman was employed as a mall security officer in Anchorage, according to the Department of Law.

The charges amount to four different victims and eight different assaults, according to the Department of Law. The sexual assaults are alleged to have occurred from 2011 to 2018.

Anyone who may have any further information regarding Heitstuman is asked to call the FBI Anchorage Field Office at (907) 276-4441.
