CALDWELL -- A young Nampa man died early Tuesday morning after a crash east of Caldwell.

A passing driver spotted the wrecked vehicle near the intersection of Ustick Road and Midland Road at about 8:30 a.m. and called authorities.

Deputies responded to the scene and found a 19-year-old victim dead inside. He was the only person in the vehicle, deputies say.

Investigators believe the crash happened at about 3 a.m., but was not immediately discovered because the vehicle ended up off the roadway.

Speed and alcohol may have been factors in the wreck, deputies say.

The victim's name has not yet been released. The crash remains under investigation.
