It began in the 1970s. A serial killer was roaming among us. The so-called Golden State Killer took the lives of 12 people, committed 51 rapes and burglarized dozens of homes across California.  Now, after all this time, there's an arrest and charges have been filed against a 72-year-old former police officer.  Also on today's show... we all buy things based on reviews we see online, especially on Amazon... but many of those are fake... and paid for!   And... the long awaited Marvel movie "Avengers: Infinity War" opens Friday. How big of a box office bang will it make?
