J.B. Harold Murder Club solution? (Spoilers!)

[dave_van_damn]

Can't figure out who the murderer is and how to make them confess. I've arrested everyone and have managed to make the following characters' portraits turn green:

Edward Robbins
Fred Robbins
Janet Robbins
Ralph Carrington
Shelly McDonald
James McBain
Stanley Howard

My stats are as follows:
Evidence: 87
Interview: 100
Interrogation: 83
Information: 100
Average: 92

I've searched the following places:
B. Robbins' House
E. Robbins' House
The Randle Clinic
Dr. Randle's House
S. Howard's Apt
The Carrington's
J. McBain's House
Shelly's Apt

Any tips on what I should do next? Edward and McBain have both said Harry Klien killed Bill. I assume I still have some evidence I need to find but I've looked everywhere!

Listen to this soundtrack whilst you attempt to solve the game:

That's from LaserDisc Manhattann Requiem.

Finally finished it. After typing up all the places I had warrents for I realised I had missed a few clues.

Best way to finish the game? Write everything down.

Peace
