DENVER -- The ex-wife of a Pitkin County prosecutor was arrested this week, accused of trying to have him killed so she could have full custody of their daughter.

Elinor Dvir, 36, was arrested Sunday in Denver on suspicion of solicitation to commit murder and is being held at the Jefferson County Jail on $100,000 bond.

Dvir on Saturday told an undercover police officer posing as a hit man that she'd give him $2,000 to kill her ex-husband, Richard Nedlin, and make it look like an accident, according to court documents. Nedlin is a deputy district attorney who lives and works in Aspen.

Dvir and Nedlin are in a contentious custody battle, and Dvir told the undercover officer that killing Nedlin was the only way to get her daughter back, according to court records.

Both were due in a Pitkin County courthouse Tuesday for a child custody hearing.

Calls to the Pitkin County courthouse were not returned.

Police started investigating after Dvir allegedly approached an acquaintance and asked if he knew anyone who would kill her ex-husband. The acquaintance, a confidential informant for the police, then contacted law enforcement officers and alerted them to Dvir's alleged plot. Dvir initially tried to hire the confidential informant to kill Nedlin, authorities said.

Dvir told the informant that she'd been arrested and served 18 months in jail for "importing diamonds from Israel," court records said. She said the jail term was another reason she was mad at her ex-husband and wanted him dead.

The informant told police that Dvir worked as a prostitute, advertising on Craigslist under the name Capri, the affidavit said.

The informant said he met Dvir through the Denver Metro VIP Escort Service, and that she said she had been fired from the escort service for not turning in all of her receipts, according to the affidavit. The informant said he would drive her around to jobs and that's how they became better acquainted over two weeks.

Once the undercover officer met Dvir at her home on South Grant Street Sunday afternoon, Dvir described to him the kind of car Nedlin drives, his habits and the floor plan of his house in Aspen.

She explained that she would immediately be suspected if her ex-husband was killed so she wanted to make it look like an accident or for the hit man to leave no trace, according to the affidavit.

"My biggest fear is that they (the police) are going to come after me. I could lose my green card, get deported, and go to jail for a life time. That's why I didn't want to make him gone from this earth, maybe just make him a veggie ... because if he's dead, I'm dead," Dvir told the undercover officer, according to the affidavit. "I don't want a body laying around ... If it's an accident, it's an accident. If the body disappeared, that's fine. But I'd prefer it to look like an accident, like stuff his body with cocaine, like an overdose. It's got to be done in a very smart way."

A listed phone number for Dvir could not be found. A cell phone number she had was disconnected. Her next court appearance is set for Thursday.

A spokesman for Immigration and Customs Enforcement, or ICE, confirms Dvir was in their custody from December, 2005 through September 11th, 2007 but is now a U.S. resident.

Jefferson County sheriff's deputies said Dvir agreed to do a jailhouse interview with 7NEWS, but only if the station agreed to post her bond. The station declined.
