1979" In 1987, he sued McGinniss for fraud, claiming that the author had agreed to hear his innermost thoughts in order to write a positive account of his ongoing fight for justice for himself and his family, but had actually falsely claimed to believe his claims of innocence after he had already reached a conclusion of his guilt, in order that he (MacDonald) continue cooperating with him on the project. This lawsuit resulted in a mistrial on August 21, 1987. The two later settled out of court for $325,000, although the Kassabs subsequently filed their own countersuit against MacDonald, citing an inheritance clause, resulting in MacDonald receiving only $50,000.

Further evidence he contends has been withheld include two unidentified 22 inch (56 cm) long synthetic hairs found in a hairbrush, but which were not made available to his defense at trial, and a minute spot of blood of either type O or type B origin (either
