The killing of a U.S. diplomat in Grenada Wednesday did not appear to be politically motivated, and the State Department said there was no indication he was the deliberate target of the crime.

John Butler, a political officer with the U.S. Embassy at St. George's, was shot at point-blank range when he tried to subdue the gunman, a police officer who apparently went berserk and opened fire at police headquarters before he was shot down himself.A senior Grenadian official identified the gunman as Grafton Bascomb, a senior official of the police force of the neighboring Caribbean island of St. Vincent. Bascomb was on loan to Grenada, the official said.

Albert Xavier, adviser to Grenada Prime Minister Herbert Blaize, told reporters that Bascomb was in charge of funds used for Operation Trade Winds - the recently completed U.S-financed military exercise in the Eastern Caribbean.
