Grand jury to meet March 19 to investigate Duncan murder by Christopher Smart A grand jury has been authorized by Third District Court to investigate the Aug. 4 murder of airline pilot Fred T. Duncan, according to a statement from the office of the Summit County Attorney. The official statement released March 6 said the order for the grand jury is in response to a petition filed by Summit County Attorney Robert Adkins at the request of Park City Police Chief Frank Bell. The petition was analyzed by Third District Court Judge Leonard Russon. The balance of the Third District Court judges unanimously approved Judge Russon' s recommendation recom-mendation to convene the jury. According to the statement, the grand jury will be convened March 19. It will be made up of Summit County voters. The grand jury probe of Duncan's death has been called to investigate the murder itself and any illegal conduct relating to the murder, the Third District Court order states. The county attorney's statement said that by Utah statute no further statements can be made by his office. Also, it states that no other law enforcement authority will comment on the grand jury. Duncan was killed by a single gunshot wound to the head during Art Festival weekend in the home of Park City resident Bryan Oliver at 1147 Woodside Ave. The investigation of the Duncan murder has turned up other felonious activities. Traffic in drugs and firearms may be related to the murder, according to Bell. However, "uncooperative witnesses" have slowed the investigation, Bell said. A grand jury has the power to subpoena testimony from such individuals. At the time of his death, Duncan, a Miami resident, was on leave from Pan Am Airlines. He was recuperating recuper-ating from a head injury received in a skiing accident at the Park City Ski Area in January, 1984. . Duncan was in the living room of the Woodside Avenue house with an unidentified Miami woman at the time of the murder. The woman was not injured in the shooting. Police have not disclosed whether she can identify the assailant. Bell said the prime suspect in the murder is a 26-year-old Miami man. On Aug. 24, a large caliber handgun was found by two juveniles fishing for golf balls in a pond on the Park City Municipal Golf Course. Ballistics tests revealed the gun was the murder weapon. The gun is owned by a Salt Lake City man, who claims to have sold the gun more than a year ago, according to Bell. The man says he does not remember to whom he sold the weapon, he said.
