A Mills woman will avoid any additional time behind bars, after admitting to engaging in sex within the family, and endangering children.

Thirty-three year old Robin Keene was given a four-to-seven year suspended prison sentence, with six years of probation, after she pleaded guilty to one felony charge of incest.

She was also sentenced to six months in jail after she pleaded guilty to two misdemeanor counts of child endangering, and that jail time has already been served.

According to the Natrona County Sheriff's Office, the investigation began in September 2014, when deputies received a report from a counselor, about a girl who had been sexually assaulted by her grandfather, later identified as 53-year old Glenn Towner.

An interview with the other granddaughter revealed that she also had been touched inappropriately.

These repeated contacts started as early as September 2013.

The granddaughters told investigators that they told Keene in September and October of 2013, and also in August 2014, about the sexual contacts with Glenn Towner.

Keene then confronted Towner about the contact and also told law enforcement that Towner also touched her and that she was a victim of sexual abuse, however investigators later found text messages sent from Keene to Towner and when questioned, Keene admitted to having a consensual sexual relationship with Towner.

Glenn and 52-year old Doris Towner married in July 2013, and they have had an open relationship that included many sexual encounters with Keene, according to the affidavit.

Both Towner's have been sentenced on charges connected to this case.
