BIRTH-FATHER SEARCH: Soon after his birth mother contacted him for the first time at the age of 39, adoptee Gary Stewart decided to search for his biological father. While combing through government records and news reports and tracking down relatives and friends, Stewart turns up a host of clues — including forensic evidence — that he says identifies his father as the Zodiac Killer, one of the most notorious and elusive serial murderers in history. He chronicles his search in “The Most Dangerous Animal of All.” The program will be held at 7 p.m., April 23 at the East Bank Regional Library, 4747 W. Napoleon Ave., Metairie.
