A 45-year-old Reno woman was arrested on suspicion of trying to hire an undercover detective to cut off her husband's penis, officers said.
Margaret Lynn Wilson was accused of initially trying to arrange the murder of her husband before changing her mind and asking that his penis be cut off instead.
"We were so taken back by it; she was adamant," said police Sgt. Dave Evans. "She didn't care how we did it."
Wilson was booked Saturday into the Washoe County Jail on suspicion of solicitation for murder. She was held without bail.
After contacting the detective late Friday night, she also is accused of requesting the torture of a female friend of her husband.
Police said she agreed to pay the investigator $1,000 and give him the key to her husband's home in Reno. She was arrested after allegedly paying the officer $200.
Wilson, who said she was a nursing supervisor at a Sparks elder-care facility, also was arrested on suspicion of child endangerment after her two grandchildren were found alone at her Reno home.
Police said they found a bathtub full of water, trash and beer bottles, and litter on the floor. The children - a 5-year-old girl and 2-year-old boy - were unharmed and placed into child protective custody.
Police said they had been unable to reach the husband to inform him about the alleged plot.
