Authorities Wednesday publicly identified a 51-year-old UPS truck driver killed this week in a solo crash on a rain-slicked stretch of freeway near Mission Valley.

Jeffrey Sutch of Santee was heading north on state Route 15 in Kensington when the trailer of the big rig he was driving began to fishtail as he approached Interstate 8 at about 6:15 p.m. Tuesday, according to the San Diego County Medical Examiner’s Office and California Highway Patrol.

The vehicle veered out of control, slid off the roadway and slammed into a eucalyptus tree, CHP public affairs Officer Sal Castro said. Sutch died at the scene.

The accident remained under investigation as of Wednesday afternoon, Castro said.
