Cops first ruled a 94-year-old man’s death to be natural. Now, they say his 71-year-old son-in-law killed him

A California man has been charged with the murder of his elderly father-in-law, who police initially believed had died from natural causes.

Khanh Trong Tran, 71, was arrested on Friday, just days after his father-in-law, Sy Van Nguyen, 94, appeared to have died from natural causes in his Bay Area home, the Sonoma County Sheriff’s Department said.
