A stoolie named Popcorn gives Glenn some leads, the killer’s girlfriend refuses to cooperate and says he’s a good man who pays for her son’s medical treatments. The baddie eventually kidnaps Lee’s sister Toby (Stefanie Powers, future star of Hart to Hart) to guarantee compliance, and arranges the handoff at Candlestick Park during a Giants/Dodgers game, where things go wrong for him, and he’s gunned down by Glenn Ford on the pitcher’s mound.

The baddie also sneaks up on Lee in a hallway disguised as an old woman… I forget why:
