The second season of Body of Proof, an American television series created by Christopher Murphey, commenced airing in the United States on September 20, 2011, concluded April 10, 2012, and consisted of 20 episodes.

Along with Hunt solving homicide cases are her colleagues, Nicholas Bishop as Peter Dunlop, Jeri Ryan as Dr. Kate Murphy, John Carroll Lynch and Sonja Sohn as Detectives Bud Morris and Samantha Baker and fellow medical examiners, Geoffrey Arend as Dr. Ethan Gross and Windell Middlebrooks as Dr. Curtis Brumfield.

Mary Mouser, who plays Megan's daughter Lacey, was promoted to "regular" from "recurring" status from season 1.

When a car careens out of control over an embankment, killing a middle-aged man in the driver's seat, Megan learns that all is not well on a pretty suburban cul-de-sac---where she and her team discover a neighbourhood swingers' club behind the picket fences and a possible toxicity in the soils among the homes.

When a wealthy tycoon's much younger new wife, Julie Loeb, is shot at a family deer-hunting outing, suspects abound.

Martin's ex-wife, Alexandra Loeb, had a clear financial motive, but his grown children are also potential suspects.

Murderers: Megan investigates the death of a young nanny run down by a car and discovers that the dead woman's 6-year-old charge has been kidnapped and requires medication.

A man who is presumed dead walks off Ethan's examination table, leading the team to a shocking discovery.

A horse-riding champion is found dead in the woods, and her convict workmate is a suspect in the ensuing murder case, as is the stable owner.

A murdered young woman's body turns up in place of a medical school cadaver during class, leaving Megan to rely on the eager star student to help solve the case.

Victims: Murderers: Recurring characters: Nathalie Kelley as Dani Alvarez and Joanna Cassidy as Joan Hunt.

Walter Brown, a recent multi-million dollar winner in the lottery, is found stabbed to death in his apartment with $50,000 floating out of his window.

When the owner of an Italian restaurant turns up dead in the freezer, Dr. Hunt and the team take a closer look into family matters.

Note: Sonja Sohn as Samantha Baker and Mary Mouser as Lacey Fleming did not appear in this episode.

After a car accident reveals a body in the trunk, the team is led to another, leaving them with two cases to solve, while Megan is reconnected with an acquaintance and Kate's job is threatened.

Center for Disease Control (CDC) Officer Charlie Stafford (guest star Luke Perry) takes over the case to figure out not just what caused the outbreak but who.

As the death toll continues to rise, the team needs to move quickly to figure out how to treat this virus and, more importantly, who is spreading it.

In a case of twist and turns, the killer comes back to get revenge on Megan for taking three years away that he could have spent with his daughter.

The series still feels formulaic to me, but the cast make it worth taking the time to watch and help it overcome any short comings.

The second season sees more medical mysteries and twist with each episode as Dr. Megan Hunt (Dana Delany) and her team are back to handle everything from a child kidnapping to a murder where the entire city could be suspect.

Along with murder and other crimes, the team deals with a new romance and Hunt continues to work around strained relationships with her ex-husband and boss.
