peter edelmann committed suicide. derek always thought there was more to it than that. yes, a lot more, according to his files, and none of it remotely plausible. look i'd be the first to admit that some of derek's theories... i know he was a friend, jack. this is not about friendship, sandra. it's about loyalty-- a fellow police officer whose name is about to be dragged through the mud. jack, if we take this case on, all that happens is that we end up looking every bit as crazy as derek. where's the harm in looking through the files unofficially? he may have missed something. be honest, jack. if this file landed on your desk, and you'd never even heard the name derek brooker-- i know, i know. i'd think he was several sandwiches short of a picnic. but i knew derek, and he was a good detective. and if he thought that edelmann's death was suspicious, he must've had grounds for it. okay, then. put it on the board.
