Three Maryland men, identified by police as a members of the Pagans motorcycle gang, have been charged with murdering a soft drink salesman in western Fairfax County, police said yesterday.

A Fairfax police spokeswoman said one of the men was arrested Tuesday at his home in the Mount Rainier section of Prince George's County and the others are being sought on murder warrants in the Saturday night shotgun slaying of John J. Goodwin, a Coca-Cola salesman, who was killed in the Chantilly area. Police initially did not announce the arrest of Michael P. Bourque, 29, of Mount Rainier because they feared the two other men would flee the area, said Officer Connie Curran, the spokeswoman.

The two, Eugene Windsor, 26, of 2819 Randolph Rd. in Montgomery County and Anthony Raffo, 29, a Prince George's County resident, apparently learned of the arrest and eluded officers, Curran said. Both are considered armed and dangerous, she said.

Police said the three men were quarreling with the owner of a house on Lee-Jackson Memorial Highway over custody of a motorcycle when Goodwin, 28, a Fairfax County resident, arrived in a soft drink truck. He was delivering a vending machine to the house for storage.

"Two of the men came out of the house, saw the victim, forced him into the house and shot him," said Fairfax police spokeswoman Judy Dailey. Goodwin was pronounced dead at the scene from a shotgun blast to the upper back.

Police said Goodwin was not involved in the argument over the motorcycle and that they were trying to determine a motive for the slaying.

Goodwin "had nothing to do with the Pagans," Dailey said. "He just happened to be at the wrong place at the wrong time."

Dailey said the owner of the home was an acquaintance of the three men who have been charged in the shooting.

Bourque is being held in the Prince George's County jail, where he is awaiting extradition to Virginia
