Names of brothers killed in Lakeside collision released to public

SAN DIEGO (KUSI) – The names of two brothers from Spring Valley killed in a possible DUI collision last weekend were released Tuesday.

According to the county Medical Examiner's Officer and California Highway Patrol, 24-year-old Geordan Dunkle lost control of his 1999 Saturn sedan on Wildcat Canyon Road in the Lakeside area around 5 a.m.

The northbound car veered across a set of solid double yellow lane markers and crashed into an oncoming 2000 Toyota Camry just north of Blue Sky Ranch Road and overturned. 

According to CHP Officer Berek Downing, Dunkle and his 26-year-old brother, Gregory, died at the scene.

A 25-year-old Chula Vista man riding in the back of the Saturn suffered severe injuries in the wreck, as did the 42-year-old El Cajon man behind the wheel of the Camry. The surviving driver's 53-year-old male passenger, also an El Cajon resident, was left with moderately serious trauma.

Open beer bottles and marijuana containers were found in the Saturn. 

A determination on whether Geordan Dunkle was under the influence of alcohol or cannabis at the time of the crash remains on hold pending completion of postmortem toxicology tests.

It was the second time within 10 days that a pair of brothers in their 20s died together in a head-on collision on a San Diego-area rural road.

On July 17, two Escondido brothers, Alexander and Andrew Parks, were killed when a 2002 Mazda Miata crossed into oncoming traffic and smashed into a box truck on the I-76 in the Rincon area. 

The died in the wrecked of the two-seat vehicle.

The 49-year-old driver of the cargo vehicle and his 43-year-old male passenger suffered minor injuries, the CHP reported.

It was unclear why Andrew Parks lost control of the car.
