United States v. Lindstrom
United States Court of Appeals for the Eleventh Circuit
698 F.2d 1154 (11th Cir. 1983)
Dennis Slater and Joanne Lindstrom (defendants) were charged with insurance fraud in connection with their therapy company, and a former employee testified as the prosecution's key witness that she had helped alter patient records and had been ordered to falsify billing at Slater's and Lindstrom's direction. On cross-examination, the defendants sought to show the witness harbored a vendetta against them by asking about specific violent, manipulative episodes tied to her documented psychiatric illness — including offering money to have someone shot, firing a gun into a home, and an involuntary commitment and manipulative suicide attempt — but the trial court excluded most of this questioning, and the defendants were convicted.
Whether a party may cross-examine a witness about her history of mental illness and resulting conduct.
