The murdered cop has a small part acting with Ford in Working Girl

Both movies have been playing on cable recently, so I noticed the connection.

If you see Working Girl, watch the scene where Melanie Griffith and Ford go to their first meeting with Trask industries (right before they first sleep together). They sit in a room with two cold businessmen, one of whom mentions Trask doesn't sit in on meetings at that level, and a few moments later picks up the phone to receive word from Trask. This person is the cop who gets killed at the train station (Ford and him must have had a few laughs during that day's shoot remembering working on Witness together, albeit not in the same scenes).
