THE MURDER OF A SEATTLE WINE STEWARD DRIVING HOME PUT THE CITY ON EDGE - WAS IT ROAD RAGE, OR WAS THE GUNMAN A SELF-TAUGHT KILLER INTENT ON FINDING THE PERFECT MOMENT TO KILL?

"48 HOURS" INVESTIGATES IN "STUDENT OF MURDER," SATURDAY, SEPT. 10

Peter Van Sant and 48 HOURS investigate the death of Yancy Noll, who was killed while driving home from work, and the trail that would lead police to an unlikely suspect in an encore of "Student of Murder," to be broadcast Sept. 10 (10:00 PM, ET) on the CBS Television Network.

The murder grabbed the attention of Seattle's commuters. Noll had no criminal history, wasn't known as a hothead, and his personal life didn't give police any clues to explain why someone would want him dead. Then police got a tip that led to Dinh Bowman, a dazzling engineer with his own boutique robotics business. As police looked closer, they uncovered evidence that they said revealed that Bowman was good at many things, including murder. But could this evidence lead to a conviction?

48 HOURS: "A Student of Murder" is produced by Paul LaRosa and Jonathan Leach. Linda Martin is the update producer. Doreen Schechter and Phil Tangel are the editors. Al Briganti is the executive editor. Susan Zirinsky is the senior executive producer.
