Police in Georgia say they are taking a second look at the 2013 heroin overdose death of a man connected to the woman charged in the overdose death of a Google executive.  Police say Alix Tichelman called 9-1-1 to report that Dean Riopelle had overdosed on heroin in September of last year. McCarty says a medical examiner concluded Riopelle did in fact die of an overdose.  However, he says investigators want to take a second look to make sure they did not miss anything.  Tichelman is charged with manslaughter in the November death of Google executive Forrest Hayes.
