On her 18th birthday in March 1976, Jones gained control of saved earnings from her work in Family Affair, about USD 180,000 (roughly equal to $700,000 in 2009) which was being held in a trust fund and U.S. Savings Bonds. Jones and her brother Paul then rented an apartment together not far from their mother. Five and a half months later, in the early morning hours of August 28, 1976 after partying all night in the beach town of Oceanside, California with her new boyfriend Allan (Butch) Koven and others, Jones was found dead in the bedroom of a house belonging to the parents of a 14-year-old friend named Helen Hennessey. The coroner 's report listed her death as an accidental drug overdose.
