Dalton Carlson entered a Sonoma County courtroom Wednesday shackled to a wheelchair. He’s been arraigned on charges that he killed his father and his wife last week in Santa Rosa. He’ll be back in court March 14th to enter a plea. Judge Elliot Daum will be on the bench for that appearance. Santa Rosa police have still not released a motive for those crimes, or a specific cause of death for Dale Carson or his daughter-in-law Jessica. Dalton Carlson was also charged with burglary and violating the restraining order his wife had against him.
