San Diego Murder-Suicide Investigation – Three Found Dead in Lake Murray Home

A San Diego murder-suicide investigation is underway after three people were found dead inside a home in the Lake Murray area on Wednesday morning, September 16, 2026. San Diego police responded to a welfare check at a residence in the 6800 block of Boulder Lake Avenue, where two adults and a juvenile were discovered deceased with gunshot wounds.

Police have described the incident as an apparent isolated case, with investigators examining the possibility of a murder-suicide. The identities and ages of the victims have not been publicly released as authorities continue working to establish the circumstances surrounding the deaths.

According to reports, a neighbor became concerned after not seeing the family and after hearing what she believed were gunshots during the previous night. The neighbor later went to the residence to check on the family and discovered the victims inside before contacting authorities.

San Diego Police Department homicide investigators responded to the home and began processing the scene. Police have indicated that there is no ongoing threat to the surrounding community and that investigators are not currently searching for a suspect.

The deaths have left the Lake Murray community shaken as authorities continue working to determine exactly what happened inside the residence. The investigation remains active, and additional information, including the identities of those who died and the circumstances leading to the shooting, is expected to be released as officials are able to confirm further details.

Authorities have not announced a final determination regarding the manner of death, and the murder-suicide theory remains part of the ongoing investigation.
