Tom Cooley was a serial killer from Julie's past in Seattle.
Tom Cooley grew up outside Seattle and came from a wealthy and influential family that had made its money dealing in real-estate. At Hardison High, he graduated in 1987 and was the senior class president. Despite this, he grew up to become a rapist, apparently starting as early as when he was in high school, when he and two of his closest friends, Max Liston and Gavin Pearson, drugged and raped a woman named Marla together. When Liston and Pearson, thinking she was dead, were about to bury her on Cooley's ranch, she woke up and escaped. As she ran, Cooley told her that nobody would believe her. In adulthood, Cooley became a serial killer, raping and killing young blonde women who went to bars near his office building. Liston and Pearson, with whom he stayed in touch, were apparently at least partially involved in the killings. Pearson, who got a law degree and the right to practice, became Cooley's lawyer. Liston, with some financial aid from Cooley, got into the construction business.
In 2010, Cooley killed Janet Warren and buried her with the other victims he had killed over the years. Finlay investigated the case and, though the body wasn't recovered, she was able to find evidence incriminating him, including semen. Unfortunately, she obtained the DNA sample proving his guilt in the case by breaking into his house and taking a used glass. The sample was legally dismissed and Cooley, publicly dismissed as a suspect, filed lawsuits against the Seattle police and Finlay personally and won. Russell was eventually forced to fire her. Afraid that the bodies might be exposed, Cooley had Liston dig them up and rebury them in a land preserve in Nevada, ensuring that they wouldn't be dug up again, and then used his contracting firm to have the Cooley ranch (along with the original burial ground) demolished and turned into a residential area along with the surrounding area, ensuring that the original crime scenes couldn't be dug up again either.
Cooley's victims were athletic, attractive blondes in their early 20s. He would find them in bars and near his office, drug them with flunitrazapam, drive them to his ranch, rape them and kill them by strangling them. Their bodies would then be buried on his family ranch.
