On Thursday's episode of The Mentalist, Teresa Lisbon is in trouble.

A pedophile she arrested, and who was recently paroled is found dead. Lison's fingerprints are on the gun's magazine and she's the prime suspect in the murder.

Naturally, Jane and the CBI team set out to prove their colleague's innocence. Watch the official CBS trailer for "Red Badge below," followed by a few episode stills from the hour:
