The case is 8 months old and going cold.  Both law enforcement and the victim’s family are pinning their hope for new leads on a billboard campaign that is scheduled to start this week.  The family is hoping that the East Atlanta billboard will spread the word about a $25,000 reward that may motivate anyone with information on the May 2013 murder of Patrick Cotrona to come forward.  Cotrona was killed in East Atlanta while walking to a restaurant from his home.  Police say they have exhausted all the leads that have come in since the crime occurred and are hoping that the billboard will give them some new information about the killer.  To read a letter from the victim’s family, click here.
