The 40th anniversary of the arrest of David Berkowitz, who killed six people and wounded seven in a1976 spree, brings another documentary, “Son of Sam: The Hunt for a Killer” (Investigation Discovery, 9 p.m.).
The New York serial killer was deceptive, Dr. Scott Bonn, who interviewed him in prison four years ago, told reporters at the TV Critics Association summer press tour recently.
“This transpired after two years of lengthy correspondence with him, and I felt I got to know him pretty well through the mail,” Bonn said. “And then meeting him was it was shocking. The images that I had were this sullen young man, brooding young man who was terrorizing New York, and the David Berkowitz today looks almost like an elf, like a gnome like character with bulging red cheeks, and he came bounding in. He gave me a huge hug. He insisted that we pray together because he now calls himself Son of Hope. That’s his new moniker.”
Berkowitz didn’t participate in the documentary, which runs two hours.
