Trevor Micheal Dorion, 24, was arrested at the Stanislaus County Jail, where he had been held on a separate robbery charge, the Modesto Police Department reported.
John Parodi, 69, and his 59-year-old sister were found dead June 5 in the home they shared in the Coralwood mobile home park, east of McHenry Avenue and south of Claratina Avenue.
Dorion remained in jail Wednesday night without bail on the two new murder charges.
