The Sound of Pursuit Podcast 9.23.25 – The Pebble in His Shoe
Mike Spencer is no stranger to chasing the truth. A former journalist turned Bay-Area private investigator and longtime Pursuit contributor (thank you, Mike), he’s the author of Private Eye Confidential: Stories from a Real P.I., and a familiar voice on our podcast.
In our latest episode, Mike opens up about a haunting unsolved case he worked back in 1998. He calls it “the pebble in his shoe”, a murder that’s stayed with him for over two decades.
That story has evolved into his own podcast:
The Gary Murphy Assassination: A San Francisco Cold Case
Join host Hal Humphreys and Mike Spencer for a powerful conversation about justice, obsession, and the long road to answers.
