They begin to suspect Kevin Donovan, a thieving drug addict who works at the church, until he is found murdered in his apartment. As Goren and Eames delve into the church's business, they uncover the embezzlement of money from the collection funds, and believe it was by Abernathy who tried to frame Donovan.
