Four people have been found dead in a multimillion-dollar home in San Francisco as police investigate their “suspicious” deaths. 

The gruesome scene was discovered at 1:23 p.m. Wednesday when officers conducted a welfare check on the 900 block of Monterey Boulevard in the affluent neighborhood, the San Francisco police said.

The four victims, believed to be family members who lived in the home, were pronounced dead at the scene. Two sources told KTVU-TV that the incident is being investigated as a possible murder-suicide, though San Francisco police said they are treating it as a case of suspicious deaths. 

“This is a very rare occurrence in this neighborhood,” Officer Robert Rueca, a spokesperson for the San Francisco Police Department (SFPD), told the local outlet. “This area rarely sees any type of activity close to this.”

Officers were seen combing through the Spanish-style house and the surrounding neighborhood for evidence on Wednesday. According to online records, the home sold in 2014 for $1.35 million. The home is 1,755 square feet and has three bedrooms and one bathroom.
