San Bernardino Police Chief Jarrod Burguan said during a news conference Tuesday that the couple, both 53, had been in a relationship for about four years and that, soon after they married in late January, they separated. The police chief said it appeared that Anderson had been attempting to contact Smith and persuade her to return home, but she was resistant.
Those closest to her said that she had mentioned that his behavior was odd and that she was concerned about his behavior, and that he had made some threats toward her, Burguan told reporters. He did not make a specific threat to shoot her.
We were also told from the family that she didnt necessarily take those threats seriously.

After the shooting, police searched Andersons home, seizing electronic devices and a handwritten note that made references to Anderson and Smiths relationship, feeling dishonored and moving forward with no regrets, Burguan said, adding that it was not considered a suicide note and that, without the shooting, the letter would not have raised any alarms.

He said Anderson seemed a bit different at first, but later revealed himself to be paranoid and possessive.
It was that behavior, he said, that led Smith to leave Anderson just months after the couple were married.
