NEW YORK – Police said the lone gunman who killed Minnesota insurance executive Brian Thompson on a Midtown Manhattan street took off on an electric bike into Central Park and disappeared. Surveillance showed a hooded man with a gun equipped with silencer. He was in a hoody and in some video was masked. On the street, police said, they found three shell casings. The words “deny,” “defend” and “depose” were written on the casings. The words suggest a link to a growing movement against the giant insurance industry. The movement has picked up traction since a 2010 book by legal scholar Jay Feinman — “Delay, Deny, Defend: Why Insurance Companies Don’t Pay Claims and What You Can Do About It.” Feinman calls for consumers and lawmakers to fight back.
