But now there's this.
A former boyfriend of Cryer's ex-wife, Sarah Trigger, claims in court documents that it was Trigger who wanted to orchestrate a hit on both Cryer and her estranged husband, David Dickey. Trigger has vehemently denied the allegations.
News of the purported plot first surfaced last month, according to sworn statements by the 44-year-old Cryer as part of their ongoing divorce case.
According to the document, Trigger's lawyer, Angela diDonato, claims her client had just broken up with a guy named Eddie Sanchez and that he informed Trigger that he was going to kill Cryer and Dickey. Startled, diDonato contacted both men's attorneys to warn them and suggested they take out a restraining order against Sanchez.
In a separate affidavit, Dickey says he confronted Sanchez about the allegations, and Sanchez blamed the whole scheme on the British-born Trigger. She and Cryer married in 1999 and had a son, Austin, now 9, before the two bitterly divorced in 2004.
"Mr. Sanchez not only flatly denied making such a statement, but he said that it was [Trigger] who had contacted him on numerous occasions, stating that she wanted to see the pair [Cryer and Dickey] dead, and even asking Mr. Sanchez if he would kill the pair," the court documents state. "Or if he would not, inquiring whether she could speak with Mr. Sanchez's father about this issue."
Dickey says in the documents: "Mr. Sanchez then told me that [Trigger] had created this story as a method to control him and to prevent me from speaking to him regarding the child custody matter, as he had enough proof for her to lose custody of her children."
Indeed, Trigger has her own problems. She was taken into custody last May on suspicion of child abuse after Dickey, from whom she's now separated, contacted police about an injury sustained by their 3-year-old son. That case is still pending.
Cryer, meanwhile, says in court documents that he and his reps have chosen to keep mum on the whole sordid subject to protect Austin.
The Emmy winner says he informed producers of his show of the alleged threats in mid-January, at which point security was heightened on the Two and a Half Men set. That week's taping went ahead as scheduled, while the FBI investigated the matter.
An attorney for Cryer did not return a phone call seeking comment. Dickey also declined to comment. Attempts to reach Sanchez and his lawyer were unsuccessful.
Meanwhile, another Trigger lawyer, Vicki Greene, tells E! News that the erstwhile Duckie stated under penalty of perjury that he "never accused Sarah of hiring a hit man."
Adding further confusion to the twisted tale is a voicemail message left by Sanchez when he was apparently trying to reach Trigger at her mother's home.
"I've been interviewed by federal agents and lawyers are calling me," he says. "I just want to know how Sarah's doing...I know she didn't do anything...I just wanted for you to tell her that I explained to those people everything."
The recording, says Greene, shows Trigger's innocence.
"Sarah did not threaten Jon or anyone," adds Greene. "Jon and David are litigating against Sarah in two different courts at the same time and are using anything they can get their hands on, even the press, against Sarah."
The plot thickens.
