An Idaho man has been arrested on nearly two dozen counts of sexually abusing two women while they were children living in Wasilla, after a six-month investigation by Alaska State Troopers.

According to an AST dispatch issued late Friday, troopers’ Child Abuse Investigation Unit was approached Nov. 8 by a 23-year-old woman, who said that both she and her 22-year-old sister had been abused by 52-year-old Anthony Gilliam.

“Gilliam is currently living in Idaho,” troopers wrote. “After an extensive investigation on (Friday), Palmer District Court issued a warrant for the arrest of Anthony Gilliam.”

In an email to Channel 2, AST spokesperson Beth Ipsen says Gilliam, a relative of the women, allegedly assaulted them in Wasilla.

“They were young children into teen years,” Ipsen wrote. “It started in 2003 and went on for quite a few years.”

It’s not immediately clear whether anyone beside the people directly involved in the assaults were aware of them, Ipsen says.

“There's no other victims, otherwise that's still under investigation,” Ipsen wrote.

After receiving the Alaska warrant, Idaho authorities took Gilliam into custody without incident on the same day it was issued.

“Ashton Police Department has been assisting with this investigation from the beginning and on (Friday) they executed a search warrant along with the Freemont County Sheriff's Department at (Gilliam's) Idaho residence,” troopers wrote.

Gilliam’s warrant includes 22 counts of sexual abuse of a minor and three counts of coercion. He is being held pending extradition to Alaska; the warrant sets his bail at $500,000, with a court-approved third-party custodian required for release.
