A woman who sought several times to have her husband killed after he coerced her to stay in their marriage by threatening to reveal her sexual abuse of a 14-year-old boy has pleaded guilty, Monroe County authorities said.

And the husband who coerced her has also pleaded guilty, authorities said.

Robin Transue, 43, who has a listed address in the first block of Knox Street in Mount Pocono, and Keith Transue, 43, a Bushkill Township police officer who showed the same address in court papers, will be sentenced March 20, the county district attorney's office said.

Robin Transue pleaded to solicitation to commit aggravated assault and statutory sexual assault, authorities said. She faces up to 30 years behind bars and a $50,000 fine on the two felony charges. Numerous charges were withdrawn.

Keith Transue faces up to two years behind bars and a $5,000 fine on the misdemeanor charge of criminal coercion. Remaining charges were withdrawn.

Robin Transue drew friend Richard Warner into several incomplete plots to kill Keith Transue -- including a proposed hunting accident, a house fire and the use of medication to cause a heart attack, the district attorney's office said.

Warner alerted law enforcement and agreed to wear a wire, authorities said.

The death plots came after Keith Transue found out about Robin Transue's sexual involvement in 2010 with a 14-year-old boy, the district attorney's office said.

Keith Transue didn't report the crimes in return for his wife staying married to him, authorities said.

"He would later tell a fellow officer that he had dirt on his wife that he would use if she tried to leave him," the district attorney's office said in a news release.

Keith Transue's bail was $25,000 unsecured while Robin Transue's $50,000 bail was posted in January. Neither was in custody as of Wednesday morning, records show.

Keith Transue had been on paid administrative leave last spring, police Chief Mike McLouth said at the time. McLouth on Wednesday said Keith Transue had submitted his letter of resignation.

Robin Transue's attorney Steven Mills and Keith Transue's attorney Thomas Sundmaker couldn't immediately be reached Wednesday morning for comment.

Authorities thanked Warner for coming forward.

"We would commend the efforts of Mr. Warner whose cooperation with authorities likely prevented a homicide and also brought to light a sordid history of sexual assault and criminal coercion," First Assistant District Attorney Michael Mancuso said in the news release.
