Ann Jenene Cinnamon, or Ann Jenene Greer, 41, of Sterling, plead guilty Feb. 1 to hiring a hit-man to kill her boyfriend’s “mistress.”

Cinnamon plead guilty to murder for hire, which carries a maximum penalty of 10 years in prison. Her sentencing is scheduled for May 4, 2012.

Neil H. MacBride, United States Attorney for the Eastern District of Virginia, and James W. McJunkin, Assistant Director in Charge of the FBI’s Washington Field Office, made the announcement after the plea was accepted by United States District Judge Liam O’Grady.

She was arrested Oct. 20, 2011 after allegedly hiring someone to kill her boyfriend and his mistress.

According to federal court documents, Cinnamon contacted a man she found through a website called “Be Naughty” and Facebook in August to see if he had any friends who could “do her a favor and help her out with a problem.” Cinnamon said that she wanted her boyfriend’s mistress murdered and the man said that he would see if he could help her.

The man contacted the FBI and became a confidential informant in the case. He began recording conversations with Cinnamon.

A meeting between Cinnamon and the confidential informant on Sept. 29, 2011 in her Sterling home was recorded and monitored by FBI special agents.

Cinnamon told the informant that she wanted the mistress’s life to be a “living hell [and] nothing to work for her,” according to documents. She also provided the informant with information of where the mistress lives and other personal information. The informant said he’d ask some of his “friends” if they could help.

Cinnamon also told the informant that she’d pay him $500 or $1,000 to take care of her problem.

According to court documents, Cinnamon scrambled to get the money together during the first couple weeks of October. By Oct. 11, 2011 the informant pressed Cinnamon on telling him that she wanted the mistress killed.

“I want her gone,” Cinnamon said, according to documents. He asked what gone meant and she responded, “Gone is killed, dead, gone, I want nothing left, no remains, nothing.”

The informant told her that his “friend” would be in town soon and would kill the mistress for $500 with a $100 down payment, according to documents. They met on Oct. 15, 2011 in Cinnamon’s van at the Great Falls Plaza in Sterling where she made a down payment and confirmed that she wanted the mistress killed. The entire meeting was video and audio recorded by the FBI.

During the late hours of Oct. 19, 2011 into the early hours of Oct. 20, 2011 Cinnamon called the informant to ask why the hit wasn’t done and said she wanted it “done now,” according to documents. The informant told her that it would be done by the end of the week, and Cinnamon then stated she also wanted her boyfriend dead and for the killing of the mistress to appear as though the boyfriend murdered her, according to documents.

The two met again at the Great Falls shopping center Oct. 20, 2011 to discuss the murder plot and payment. The informant told her that the slaying would appear as a home invasion that resulted in murder, according to documents.

Cinnamon was arrested at the Great Falls shopping center Oct. 20, 2011 for violating Title 18, United States Code, Section 1958 (murder for hire) on Oct. 20, 2011 in Sterling. Cinnamon also appeared in federal court in Alexandria on Oct. 25, 2011 and is in federal custody in Alexandria.
