CLEARLAKE OAKS, Calif. – Sheriff's officials are investigating the death of a Clearlake Oaks man that has been termed “suspicious.”

Early Friday evening, sheriff's deputies, a sergeant, a lieutenant, two investigators and evidence technicians were at the scene, located at a two-story home at the end of the cul-de-sac on Bass Lane in the Clearlake Keys area.

Crime scene tape was placed across end of the street while the investigation got under way.

“We have a dead male inside the residence,” said Lt. Steve Brooks.

“It is suspicious,” he said of the circumstances surrounding the man's death.

Shortly after 3 p.m. Northshore Fire and Cal Fire medics were dispatched to the home on the report of a possible death, based on radio reports.

Central Dispatch indicated during the initial calls that sheriff's deputies were en route, as the female caller became “highly irate” when she was asked for details by a dispatcher. Dispatch reported that there were a history of responses to the residence for disturbances.

Firefighters arriving at the scene confirmed there was one deceased individual, and termed the scene “suspicious,” with an aggressive dog and a distraught resident of the home in the room.

At the scene Friday evening, Brooks confirmed those details of the initial call.

While detectives and deputies walked the scene, a female subject sat in the back of a sheriff's patrol car.

When the group of law enforcement officials approached the car and spoke to her through the window, she became agitated and began hitting the driver's side rear window with her head and hands.

Brooks said she was in custody on “unrelated charges.” He and investigators on scene confirmed having previous contacts with the woman.

Deputies then transported her from the scene. As the patrol vehicle in which she was riding pulled away, she began rocking back and forth, and appeared to be kicking the seats in front of her.

At about 6:30 p.m., investigators and crime scene technicians were waiting to process the scene pending the signing of a search warrant by a judge, Brooks said. He expected the warrant to be delivered at any time.

Sgt. John Gregore said he and deputies initially had entered the home to secure the scene and make sure there was no one else inside.

He said they also went to the home next door and secured it.

While waiting for the warrant, detectives spoke to a man who was staying at the home of a relative a few doors down from the home where the death occurred.

Separately, that individual told Lake County News he was aware of one male and one female living at the residence, and had spoken to them and visited the home in recent days.

Additional details will be posted as they become available.
