BOULDER, Mont. (AP) _ ''Dallas'' star Patrick Duffy thanked his fans Thursday for their concern and love but asked for privacy as he and relatives mourn his slain parents.

A statement from the actor, who plays Bobby Ewing on the popular CBS television series, was read to reporters outside the sheriff's office in Boulder on Thursday, a few blocks from the bar where Terrence and Marie Duffy were gunned down Tuesday night.

''Up until now, I never fully appreciated the loyalty and depth of concern my fans all over the world had for me and the character I portray,'' Duffy said in the statement.

''To those who have voiced this concern, I want to thank them for their love and for understanding my family's need for privacy at this time,'' he said.

He remained in seclusion with his wife, Carlyn, and sister, Seattle Police Lt. Joanne Hunt, frustrating photographers from as far away as West Germany who roamed the main street of the town of 1,500 looking for him.

In the statement read by Bob Crutchfield, a spokesman for the producers of ''Dallas,'' Duffy and his sister said:

''One of the most difficult things has been our inability - due to the tremendous media coverage - to personally be with those people who loved our parents and whom we love,'' they said. ''Hopefully, as time passes, we will be able to contact these friends.''

At the request of his parents, no funeral or memorial service will be held, and their bodies will be cremated, said Crutchfield, a spokesman for Lorimar- Telepictures.

Crutchfield said he did not know how long Duffy would remain in Boulder, but probably not much more than a couple of days. Lorimar has been able to shoot around Duffy's character during his absence.

The Lorimar spokesman, flanked by Jefferson County Sheriff Tom Dawson at the news conference, declined to comment on the crime. Dawson did not speak.

Earlier, Dawson met with the actor and members of his family, the sheriff's office said.

Duffy's parents were shot in the chest Tuesday night at The Lounge, a quiet bar decorated with pictures of their son, in what Jefferson County authorities said was an apparent robbery.

Sean A. Wentz and Kenneth A. Miller, both 19, were charged with two counts each of deliberate homicide Wednesday in Helena and were ordered held lin lieu of $500,000 bond each.

Law enforcement officers declined to give additional details about the case Thursday, citing a gag order imposed by state District Judge Frank Davis Wednesday.

Vern Sutherlin, co-publisher of the weekly Boulder Monitor, said he was told by a patron in the bar Tuesday night that two men matching the descriptions of the Helena men were seen in the bar Tuesday night.

Bartender Rex Davison estimated there was $750 to $775 in the till when he left about four hours before the shootings.

Friends said the couple had been thinking of retirement.

Boulder residents had expressed shock at the shooting Wednesday, but by Thursday many said they were angry and afraid that justice would not be served.

Doug Kettle, 36, a gold miner, was typical of those calling for strong action.

''I say paint them red and turn them loose,'' he said Thursday. ''It's hunting season, ain't it?''
