The man behind the DNA discovery in the Dana Ireland case said Hawaii County police had enough to arrest the suspect on July 19. Instead, Albert Lauro, Jr., was released and committed suicide four days later. Stephen Kramer, a former federal prosecutor and the man who co-founded the FBI’s forensic genealogy team, said a DNA match from the national database CODIS was enough probable cause to arrest Lauro for Ireland’s 1991 murder.
