The San Diego County Medical Examiner’s Office Wednesday identified a 71-year-old man who died in a vehicle rollover accident off Interstate 805.

El Cajon resident Robert Roger Marchand died at UCSD Medical Center, according to the Medical Examiner’s Office.

According to the California Highway Patrol, the incident happened just after 7 p.m. Tuesday, near the Telegraph Canyon Road exit ramp off I-805.

Marchand was driving northbound on I-805 when, for unknown reasons, the vehicle went onto the highway’s right shoulder and down an embankment before landing on its roof, according to a medical examiner’s report.

Paramedics then transported Marchand to UCSD, but he died from his injuries.

Marchand was driving a Bentley Continental in inclement weather when he lost control of the vehicle, CHP Officer Salvador Castro said in a statement.

The county Medical Examiner’s Office is conducting toxicological tests to determine whether alcohol or drugs were a factor in the incident, the officer added.

According to the CHP traffic incident page, witnesses said the vehicle was “all over (the) roadway” before overturning.

Authorities shut down the exit ramp for 90 minutes following the accident, the CHP reported.
