The case of Robert Charles Browne, who may be one of America’s most prolific serial killers, was supposed to be a cold one. But that was before three retired buddies took it on.

“The score is you one, the other team 48,” wrote Robert Charles Browne in March 2000, from his prison cell in Colorado, where he was serving a life sentence for a girl’s murder. “Seven sacred virgins entombed side by side, those less worthy are scattered wide.”

No one in local law enforcement knew what to make of this message. Then three friends, volunteer members of the El Paso Sheriff’s Department cold case squad, decided to write back to Browne.

Browne boasted about having killed as many as forty-eight people in a cross-country murder spree spanning twenty-five years. As the old friends parsed the riddles, investigators followed clues leading to a confession and the closure of another heartbreaking case. This is their story.
