Zach Thaler is a low-rate thief and the direct accomplice of Ella Miyazaki, whose own skills were harnessed and improved by domineering lover Nicole Wallace. Thaler was briefly recruited by the pair to assist in cons at high-end jewelry and department stores so Thaler and Miyazaki would discreetly rob them. Wallace directed Miyazaki to get into a sexual relationship with Thaler to make him more compliant.
Once Thaler was no longer useful to the women and became a liability, they arranged an escape in a subway system from the latest jewelry store, where Wallace was waiting. In a disguise, Wallace bumped into Thaler and overdosed him on succinylcholine in his hip, while Wallace and Miyazaki continued walking in opposite directions and reconvened later. Wallace escaped again, and Miyazaki was killed by Wallace in an attempt to fake both their deaths. (CI: "Great Barrier")
