Investigation revealed that a red 1999 Mercury Sable, operated by a 17 year old female, was southbound on HWY 99W behind a box truck. A John Deere tractor, operated by Christopher Current, age 49, of McMinnville, was on Mineral Springs Rd attempting to turn left to go northbound on HWY 99W. After the box truck made a right turn on to Mineral Springs Rd, the tractor entered the intersection colliding with front passenger side of the Mercury Sable. The front passenger of the Mercury Sable, a 17 year old male, sustained fatal injuries and was pronounced deceased at the scene. The third occupant of the Mercury Sable, a 16 year old male, along with the driver, were transported to the hospital with non-life threatening injuries.
