San Mateo police found a father, mother and two 4-year-old twin boys dead inside a home, in what appears to be a murder suicide, two sources told KTVU.

"The male and female were located deceased from gunshot wounds inside a bathroom. A 9mm pistol and a loaded magazine were also found in the bathroom," police said in an updated press release.

Police also said the two children were found deceased inside a bedroom. Police said the cause of the children's deaths is still under investigation.

"The children did not have any gunshot wounds. Unfortunately, they were found deceased, so that will be part of the autopsy to figure out the cause of [the children's] death," San Mateo police public information officer Jerami Surratt said at a Tuesday afternoon press conference.

The San Mateo County Crime Lab was called to the scene and assisted officers with evidence collection. The San Mateo County Coroner took custody of the four bodies and is working to identify each person and notify next of kin.
