Actor Randy Quaid's wife Evi asked a top private detective to investigate death threats against them - but the investigator ended up filing a restraining order against Evi, RadarOnline.com has learned exclusively.
Beverly Hills-based investigator Becky Altringer claims Evi told her to harass cast members of a play her husband appeared in, and also says Evi is "mentally unstable" and using drugs.
In legal papers obtained by RadarOnline.com, Altringer says the Quaids hired her "to investigate possible insurance fraud and threat to their lives on June 5, 2009. I quit working for Evi and Randy Quaid on June 27, 2009."
According to the papers filed in Los Angeles Superior Court, Altringer claims Evi "demanded that I harass the individuals who were part of the Broadway Play, Lone Star Love because they signed a document making allegations against Randy Quaid."
After all 26 members of the Lone Star Love cast claimed Randy physically and verbally abused them, the Actors' Equity Association banned the "Brokeback Mountain" star -- brother of actor Dennis Quaid -- for life and fined him more than $81,000 in February 2008.
In her suit, Altringer says Evi owes her over $19,000 in expenses, and she also threatened "to send some thugs over to remove information from my computer and the personal belonging that she left at our residence."
Altringer also claims that on June 8, 2009, the Quaids were at her home and she saw Evi snorting a white substance.
"When I asked her about it, Evi informed me that it was Demerol and she took it for migraines," Altringer said in her suit.
In the court documents, Altringer said Evi became increasingly paranoid when the Quaids stayed with her from June 24 to June 26, 2008, at her home in La Verne, Calif.
Altringer wrote: "I observed Evi's paranoia increase and she was convinced someone was going to murder Randy and then Evi to make it look like murder/suicide. I was concerned because of the Demerol use and Evi was becoming mentally unstable."
Altringer, who runs Ariel Investigations, is waiting for the court's decision on whether to grant the restraining order.
