Arrest made 18 years after woman found dead in California river

A 75-year-old man was arrested and charged in a cold case from 2005, California police announced on Sunday. 

Philip William Frase was arrested by investigators from the Siskiyou County Sheriff's Office on Feb. 6, the office said in a statement on Facebook. He has been formally arraigned in the Sisikyou County Superior Court and charged in the "unlawful killing" of Patricia Joseph, a woman whose body was found in the Klamath River several days after being reported missing, police said. 

Joseph was 56 at the time of her death. She was found partially clothed and had been in the water for several days, police said, and a forensic autopsy revealed that she had died from multiple blunt force traumas and asphyxia.
