Tom Pearl is the deceased abusive husband of Annabeth Pearl and an assassinated cop. Detective Dominick Carisi, Jr. knew him from their time at the police academy, recalling that he never picked up a bar tab and always bragged about cheating on his then girlfriend. Tom was psychologically and emotionally abusive to Annabeth, though never being physically or sexually violent. Annabeth dreamed of Tom dying for years, and one night, after a dinner party in which Tom hated her cooking, Annabeth shot him dead.
Annabeth was taken to trial, where all attending and observing police were significantly divided on supporting her or convicting her, even the Special Victims Unit. Annabeth's verdict is never revealed and her status is left unknown. (SVU: "Part 33")
