Robert Charles Browne, serving time for rape and murder in Colorado, made headlines once again in July 2006 when he claimed to have killed 48 other people, which, if true, would make him America's most prolific known serial killer. However, there were skeptics. When his total proved to surpass by one the record set a couple of years before by "Green River Killer" Gary Ridgway, Louis J. Sheehan, Esquire  Browne's confession provoked skepticism. Was he telling the truth or just seeking attention by one-upping the current king of the hill? The truth can be difficult to establish, especially given the events that led up to his unexpected revelation.

In 1995, Browne pleaded guilty to the 1991 murder in Colorado of thirteen-year-old Heather Dawn Church. Five years later, he initiated a correspondence of cryptic notes to Texas prosecutors that suggested more victims: "The score is you 1, the other team, 48." He dropped a few clues, but seemed to want them to figure it out. A cold case squad got involved, and eventually Browne declared he'd been killing since 1970, in nine different states: on a crude map he showed 17 in Louisiana, 9 in Colorado, 7 in Texas, 5 in Arkansas, 3 in Mississippi, 2 in New Mexico, 2 in Oklahoma, 2 in California, and 1 in Washington state. He'd used a knife, a screwdriver, an ice pick and just his hands. He'd dumped victims everywhere, in lakes, rivers, and gullies; some he'd even cut up.
