Today marks exactly 6 months since Nancy Guthrie was last seen alive, after her son-in-law dropped her off at her Tucson home on January 31st.  This, as Sheriff Nanos revealed the hair sample found in Nancy’s home, turned up no identifiable leads. There is just one piece of forensic DNA left to test and Nanos acknowledged technology might not be in place to sort out the mixed DNA in the sample.  Meantime, the man arrested and detained for several hours during the early days of the investigation, is now suing Pima County along with two family members, demanding a total of $3.25 million dollars for their ordeal.
