A Mills man, his wife, and her daughter have been arrested and charged with multiple counts of incest and child sexual abuse, according to court records.

Glenn Allen Towner, 53, was charged with two counts of sexually penetrating and two counts of sexually touching his two granddaughters who were under 16 at the time of the offenses, according to the criminal information filed with Natrona County Circuit Court.

Towner, who with his family lives in the 3200 block of Salt Creek Highway, also was charged with having sex with his stepdaughter Robin Keene.

Keene, 33, was charged with one count of having sexual intercourse with her stepfather, two counts of knowing that Towner was sexually abusing his granddaughters, and falsely reporting to a law enforcement agency that she had been sexually assaulted by her stepfather.

Glenn Towner's wife, Doris Towner, was charged with one count of having sex with her daughter.

All counts are felonies, according to the criminal information documents. If convicted of all charges, Glenn Towner faces more than 100 years imprisonment, Keene faces up to 25 years imprisonment, and Doris Towner faces up to 15 years imprisonment.

According to the affidavit filed with Natrona County Circuit Court, the investigation began Sept. 11 when an sheriff's investigator received a report from a counselor about a girl who had been sexually assaulted by her grandfather. The granddaughter currently lives out of state.

An interview with the other granddaughter earlier this week revealed that she, too, had been touched inappropriately. These repeated contacts had begun as early as May 2013, according to the affidavit. That girl has been placed in protective custody.

The granddaughters told Keene in May or June of 2013, and also in August 2014, about the sexual contacts with Glenn Towner. Keene did nothing after hearing those reports, according to the affidavit.

Glenn and Doris Tower married on July 4, 2013, and they have had an open relationship that included many sexual encounters with Keene, according to the affidavit.

Thursday, Glenn Towner made his initial appearance in Natrona County Circuit Court, where his bond was set at $75,000. He is scheduled to have a preliminary hearing on Oct. 9 to determine if his case will be bound over to district court for trial.

Friday, Keene and Doris Towner made their initial appearances.

Bond for Keene was set at $50,000, and bond for Towner was set at $15,000. Their preliminary hearings have not been set.
