A prominent North county veterinarian, who investigators believe was a victim of murder, was found dead in the driveway of a Rancho Santa Fe home in January 2010.
Eighteen months later, court documents reveal his wife "was and remains a suspect" in the man's death.
On Jan. 17, 2010 Robert Stonebreaker, 53, was found dead early at a property on Paseo Delicias. His Porsche was found about a half-mile away the night before, crashed down a 15-foot embankment.
At first, investigators believed Stonebreaker walked to the home, then collapsed as a result of the injuries he received in the accident. An autopsy later revealed, however, that the 53-year-old's injuries weren't consistent with a car crash.
San Diego County Sheriff's Lt. Dennis Brugos said Stonebreaker was likely killed at the scene where his body was found and that he died of blunt force trauma.
Stonebreaker, who owned the Animal and Bird Hospital of Del Mar and a boarding facility for birds called FreeFlight, is survived by his wife, Pam and their two daughters, Kristen and Kelly.
Pamela Stonebreaker is listed on federal court documents as a plaintiff in a lawsuit involving The Guardian Life Insurance Company and Western Reserve Life Assurance Company.
The latter issued a policy to Robert Stonebreaker providing life insurance benefits of $250,000 but could not process the claim without a cause of death identified according to the court records.
The San Diego Union Tribune reports Pamela Stonebreaker's attorneys filed documents on July 18 denying she had anything to do with her husband's death.
Homicide investigators are asking anyone with information about Robert Stonebreaker's personal life that may have lead to the homicide to call the San Diego County Sheriff's Department.
