About

His testimony provides a recurring firsthand account of his relationship with Wendi Adelson, alongside the limits and challenges associated with statements he attributed to her, his travel, and his reporting to law enforcement.

Jeffrey Lacasse was Wendi Adelson's former boyfriend and testified in four trials about their 2013-14 relationship, her concerns about relocation and custody litigation, and events surrounding the period before Dan Markel's killing. He described discussions involving members of the Adelson family and recounted statements he attributed to Wendi Adelson concerning Charles Adelson, including an account that Charles had explored hiring a hitman in connection with the relocation dispute. His testimony also addressed a March 2014 dinner, his July 2014 travel to Tennessee, and the investigation that initially considered and later cleared him as a possible suspect. Across the proceedings, cross-examination examined the end of his relationship with Wendi Adelson, his recollection of conversations and dates, the timing of his reports to police, prior communications, and interview notes he later destroyed. Courts also addressed boundaries on testimony based on personal knowledge and on the use of attributed out-of-court statements.
