Mel Gaynor-Randle

Mel Gaynor-Randle is the main villainess from "I Kissed a Girl," episode 1.06 of Rizzoli & Isles.

She was played by Brenda Strong, who later played recurring villainess Lillian Luthor on The CW's Supergirl series.

Mel Gaynor-Randle is the captain of her LGBT bowling team, as well as the wife of Kelly Gaynor-Randle. As revealed later on, however, Mel was having an affair with the bartender and owner of Merch, and the couple plotted to kill Kelly and run off with Kelly's $500,000 inheritance. Knowing that Kelly was diabetic, the evil Mel poisoned Kelly's insulin pump with fentanyl and switched it with the original. Kelly left Merch and was beginning to feel the poisonous effects, and it was there that the bartender followed Kelly and bludgeoned her to death, and later penetrated Kelly with a sex toy to advert suspicion from any female.

Meanwhile, Mel participated in her routine bowling activities to create an alibi for herself, and she played the part of a grieving widow during her interview with Jane Rizzoli and Maura Isles. Mel's villainous role was revealed in the episode's climax, when she was shown meeting with her lover discussing their plans for Kelly's inheritance, which also included Mel revealing that she poisoned Kelly. The scheming villainess was shocked when her lover stated that Kelly's prints weren't on the pump, and it was at that moment that Jane resurfaced with Detective Barry Frost, revealing to Mel that her lover was wearing a wire. Both villainesses were arrested for Kelly's murder.
