Andrea Wheaton is the office manager of Senator Bryce Peterson. She was called by Bryce's wife Camille after Camille killed Brenna Lane, a model who was keeping Camille from Brenna's brother and Camille's lover, Dustin Henry, because he was much younger and emotionally vulnerable. Andrea cleaned up the scene, leaving blood on Dustin's shoes to frame him and leaving Brenna's cat at a no-kill shelter, despite being severely allergic and needing her own emergency response. Andrea stole Dustin's turpentine from his van's new paint job and burned Brenna's body in a backalley dumpster.
Dustin was originally suspected and arrested, but when he came to light he had an intimate partner, as much as Andrea put up walls, she decided to lie that she had an affair with Dustin because Andrea was getting away from her husband who wanted kids. Andrea was arrested, but Camille left a trail from an account she shared with Dustin to open his own winery, which she used for medical treatments to appear younger. Camille was confronted with Bryce and Dustin present, and she confessed in full.
Dustin was released, and Andrea took a plea to five years as an accessory to manslaughter, Camille taking a plea to twelve years for manslaughter one. (L&O: "Crashers")
