It took them five months but authorities have finally concluded that elderly twin sisters found dead at their South Lake Tahoe home in February passed away from natural causes.
Police launched an investigation into the deaths of 73-year-old sisters Joan and Patricia Miller after welfare officers discovered their decomposed bodies in the house several weeks after they died.
But only yesterday did El Dorado County sheriff's deputies announce that Joan Miller died of hypothermia after her sister and best friend, Patricia, passed away from coronary artery disease.
The women - former television stars - died within a short time of each other at the California property they shared for 40 years but authorities were perplexed as to what killed them.
Lt. Tim Becker yesterday ruled out foul play, stating that a window was open at the home, and Joan Miller died from hypothermia.
The woman was heavily dependent on her sister so when Patricia succumbed to heart disease, Joan was unable to care for herself and died shortly after.
