The San Bernardino County Sheriff-Coroner says the son and daughter of Carmen Montenegro were arrested Wednesday on suspicion of being accessories to murder.

Authorities say 25-year-old Daniel Ortiz and 26-year-old Chanel Alicia Ortiz, both of Riverside, may have helped Montenegro dispose of the remains of 63-year-old Samuel Wiggins Jr., of Diamond Bar. He disappeared on May 1.

Montenegro was arrested on Sunday after she was seen pushing a trash can containing body parts on an Ontario street. Authorities say an additional search this week turned up additional parts buried in two flower pots at a Bell Gardens home.
