A man was found dead from an apparently self-inflicted gunshot wound Friday after deputies heard a gunshot from a Thousand Oaks residence while doing a welfare check, authorities said.

The incident began at about 2:52 p.m. in the 2900 block of Salmon River Circle near Westlake and Thousand Oaks boulevards, according to the Ventura County Sheriff's Office.

Deputies were called to the residence to check on the well-being of a suicidal person, said Sgt. Eric Buschow, a spokesman for the agency. The first deputy to arrive heard one shot from inside the home, the sergeant said.

Residents on Salmon River Circle were evacuated as a precaution.

The house is in a quiet neighborhood of single-family homes.

An ambulance had been dispatched to the residence and was put on standby, Buschow said.

Despite the lack of contact with a resident inside the house, deputies treated the incident as if it were a barricade situation, the sergeant said.

Deputies shut down traffic along the cross street of East Sierra Drive to assist with the investigation.

A robot was used to help authorities figure out how to access where the man might be but it was tough to navigate because of hoarding inside the home, Buschow said.

Ultimately, a SWAT team entered the home and found the man dead from the apparent self-inflicted gunshot wound, Buschow said.

Authorities will be conducting a death investigation, he said.
