A portion of I-5 near Salem closed Monday morning for several hours, following an officer-involved shooting. Oregon State Police say a trooper stopped to help what he thought was a disabled motorist just before 9 a-m … and discovered the driver of a semi was being held at gunpoint. There was an exchange of gunfire and the suspect - identified as 31-year-old Felipe Manzo - ran into tall grass along the interstate. When officers reached him, authorities say they provided medical attention, but Manzo died at the scene.  Trooper Andrew Tuttle suffered minor injuries and was placed on administrative leave for his role in the shooting, pending the outcome of the investigation.
