Two Idaho sisters are accused of masterminding a murder-for-hire plot, the Lewiston Tribune reports.

Authorities on Thursday arrested 50-year-old Debra Wensman and 46-year-old Doris Wensman, of Greencreek, Idaho, after they allegedly agreed to pay an undercover police officer to murder their neighbor during a sting operation.

The sisters were in court Friday and charged with promoting or facilitating the commission of a crime by soliciting a person to commit murder. At the time of the Lewiston Tribune report, both were being held in the Idaho County Jail on $100,000 bonds each.

Court records obtained by the news outlet show the sisters confronted Ryan Mader, a fuel delivery driver, on Tuesday and accused him of stalking and scoping out their property at night. After Mader denied the sisters’ allegations, insisting that he had never come to their home at night, they allegedly offered him $5,000, guns and ammunition to kill their neighbor. The women reportedly told him they had previously attempted to hire another person to do the killing but the arrangement did not work out.

Mader then notified local law enforcement.

As part of a sting operation on Thursday, a sheriff’s deputy, who was wearing plain clothes and driving an unmarked car, reportedly drove to the sisters’ home and struck up a conversation with the pair. The sisters expressed their desire to have the neighbor killed and they offered the undercover officer $1,500, guns and ammunition to carry out the killing.

The sisters also allegedly gave the officer a loaded handgun in an “act of good faith,” according to the newspaper. They said they needed to withdraw money from their bank, and the trio made plans to meet later to complete the payment.

Police were listening in on the conversation and, soon after the agreement was made, descended on the residence and arrested the sisters.

Investigators found additional guns and ammunition in the home.

A preliminary hearing is scheduled for Feb. 8.

Greencreek is a small, rural town more than 200 miles north of Boise.
