Separate trials have been set for three female members of a group who are accused of sexually abusing girls under the age of 14.

Sharon Kapp, 36; Jennifer Shreeve, 25; and Amy Partridge, 27, have all been charged with two second-degree felony counts of sexual abuse of a child and sexual exploitation of a child. Kapp has also been charged with a third-degree felony count of dealing harmful material to a minor.The three women entered not-guilty pleas to all the charges Monday before 2nd District Judge Stanton Taylor. Kapp's trial was set for Dec. 4, Shreeve's for Jan. 8, and Partridge's on Jan. 15. Taylor set a pretrial conference on all three cases for Nov. 25.

The three women and the man believed to be leader of the group known as "Sisters" were arrested in August after police raided their north Ogden homes and removed nine children following an investigation by the Weber County attorney's office. The children have since been returned. The group was believed to be polygamous.

Arvin Shreeve, the group's leader, is scheduled to enter pleas on Monday to two first-degree felony charges of sodomy on two girls under the age of 14 and two counts of second-degree sexual abuse of two other girls under the age of 14.

Prosecutors say the sexual abuse occurred between 1988 and early 1991. If convicted, Arvin Shreeve could be sentenced to serve life in prison. Jennifer Shreeve and Partridge could be sentenced to serve up to 30 years in prison, and Kapp could get up to 35 years.

All four defendants were released from the Weber County Jail on their own recognizance. However, Arvin Shreeve was ordered to wear an electronic monitoring device around his ankle so officials could monitor his movements.

Weber County Attorney Reed Richards has said he hopes plea negotiations can be worked out to prevent the young victims from having to testify at trial.
