Parker Hubbard comes home to celebrate an anniversary with his girlfriend, Lily Reiser, but Lily is nowhere to be found. The bedroom is a mess and there is broken glass and blood everywhere. Stabler and Benson investigate the scene and the bloody handprint on the windowsill matches Lily's prints. Parker tells the detectives the "perv" downstairs neighbor must have done it. Stabler and Benson go to question the neighbor, Callum Donovan, but Donovan already knows Stabler: Stabler put him in jail for 19 years the last time they saw each other.
