Barbara and Tom Williams bought a duplex in Sacramento, California in 2010, and it has quite the backstory. Dorothea Puente, a notorious serial killer, owned the home in the 1980s and was accused of killing tenants so she could steal their Social Security checks. Police found seven bodies buried on the property. The room Puente used to store her victims’ bodies in before burying them is now the master bedroom. The couple says they couldn't pass up the price of the duplex, which sold for $215,000.
