The Pima County Sheriff's Department arrested David Dwayne Watson, 46, in connection with three murder cases. Victims included his ex-wife Linda Watson, who went missing from her home in August 2000, her mother, Marilyn Cox, and Cox's friend Renee Farnsworth. Cox and Farnsworth were shot to death in front of Cox's house. The sheriff's department said it believes a years-long custody battle between David and Linda Watson led to the murders.
