TUCSON, Ariz. -- Another traffic fatality Monday morning just after 10 A.M. when three vehicles crashed on Valencia Road east of Kolb.

Christopher Happeny, 18, was heading east on Valencia at a high rate of speed when he lost control of his heavily loaded pick-up truck and crossed into the westbound lane.

One on-coming driver swerved off the road down an embankment to avoid the wreck, but a second vehicle collided head-on with Happeny's truck, killing him.

The other driver was taken to the hospital with minor injuries.
