Shotgun Slade S01E16 - The Blue Dog

While Slade is visiting an old friend, he becomes the only witness to a murder and the target of those who don't want him to testify, in "The Blue Dog."

Slade witnesses Hank Galter kill Sam Berry, a restaurant owner, during a fight Galter was trying to shakedown the restaurant man for a protection payoff. As the only witness to the crime, Slade is bushwhacked because he is scheduled to testify against Galter.
