Bucks County investigators are searching for a Good Samaritan couple who found a revolver along the Susquehanna River in York County nearly three years ago.
Detectives say that weapon is linked to a 2006 homicide in Bristol Township.
The couple found the .22 caliber Smith and Wesson revolver in November 2011.
They discovered it during a drawdown of the Susquehanna River south of Wrightsville, near Kline's Run Park, Long Level at the Lake Clarke Marina, in the area of Lower Windsor and Manor townships.
The couple turned the firearm into officials at Lower Windsor Township on Nov. 1, 2011.
Bucks investigators said they "should be applauded for acting safely and thoughtfully" by turning in the weapon.
Because the revolver "may be useful in a criminal prosecution," investigators request that anyone with any information about it, or the people who found it, contact Bristol Township Police Detective Timothy Fuhrmann at 267-812-3049.
