Janet Sterling was one of the main villainesses from "If Looks Could Kill," a Season Five episode of CSI: Miami.
She was played by Kari Wuhrer.
Janet Sterling was the senior partner for J.A. Models, an agency for male models. As revealed in the episode, Janet and her partner, Abby Biggs, were also cohorts in a murderous scheme; placing insurance policies on their clients and having them killed to collect the financial benefits. Their spree began by accident; one of their models died while in a sauna, and when they saw the payout ($2 million to be exact), they decided to do the same to their other clients.
However, the evil Janet had no more plans to continue her partnership with Abby, and she put out a $6 million insurance policy on her partner. Janet gave Abby a set of lip gloss, which she laced with arsenic, but she was shot to death by Abby afterwards. Even in death, Janet successfully killed Abby when she put on the poisoned lip gloss.
