The son of a well-known Southern California radiologist is the suspected gunman in a double shooting that left his father and stepmother dead over the weekend, according to authorities.

Neighbors, attack may have been premeditated rather than random.

Police confirmed to Fox News Digital that neighbors have reached out to share what they heard and saw that day. Authorities emphasized that these accounts have not yet been confirmed, and detectives are continuing to review witness statements, physical evidence and surveillance footage.

Using license plate cameras and other investigative tools, detectives tracked Keith’s vehicle after it left the area. Police said the car was later discovered burned in another city, and a man was found nearby with a self-inflicted gunshot wound.

Severe burns initially prevented identification, but on Dec. 2, the San Bernardino County Medical Examiner confirmed the deceased man was Keith Cordes. Police believe the gun they recovered is the same one used to kill Eric and Vicki Cordes, though additional forensic testing is still underway.

Dr. Cordes had spent nearly 30 years as a board-certified radiologist with Adventist Health Simi Valley. In a statement shared with FOX 11, the hospital said it was "heartbroken by the tragic deaths of our longtime colleague, Dr. Eric Cordes, and his wife Vicki," describing him as a compassionate and beloved physician.

A GoFundMe created for the family described Vicki as "a wonderful mother, daughter, sister and a devoted grandmother whose love, joy, and presence brought light into every room she entered." The family said she "adored her husband deeply" and that her loss has left them "heartbroken and forever changed."

The investigation remains ongoing as detectives continue examining witness reports, surveillance data and pending forensic analysis. A motive has not yet been identified.
