The Sacramento County Coroner's Office has released the name of the motorcyclist killed Thursday morning on the Capital City Freeway.
He was identified as Brett Dewitt Goodenough, 52, of Elk Grove.
The California Highway Patrol said the Goodenough was riding eastbound on the freeway near Arden Way about 4:30 a.m. when for an unknown reason he lost control of his bike on wet pavement.
He was ejected from the motorcycle and then hit by a big rig. The big rig driver saw an object in the road and applied his brakes but could not stop in time.
Goodenough was pronounced dead at the scene.
