GREAT FALLS (AP) -- An organization that says inmate Barry Beach was wrongly convicted of murder plans a public-relations campaign to press for his release.

Montanans for Justice, formed Nov. 28, is raising money for what the group hopes will be a $190,000 campaign.

Beach was convicted of murder in 1983 for the 1979 bludgeoning of Kimberly Nees, 17, whose body was found in the Poplar River on the Fort Peck Indian Reservation.

Centurion Ministries, which has worked successfully to free a number of men convicted of murder elsewhere in the United States, lost an attempt to win release of Beach this year. The Montana Board of Pardons and Parole decided he will remain in the Montana State Prison, where he is serving a 100-year sentence.

Helena businessman Bob Kolar signed the papers, on the file with the secretary of state, to establish Montanans for Justice. Kolar told the Great Falls Tribune that the group's Web site, to be unveiled in about two weeks, will list ''six key facts of innocence'' in the Beach case.

''We are deeply disturbed by the fact an innocent man is in prison,'' said Kolar, present at Beach's May hearing before the Board of Pardons and Parole. ''This case isn't closed as far as we're concerned.''

Kolar said Montanans for Justice will consider billboards, television advertising and any other ''form of getting the word out to people.''

''I'm sympathetic to the Nees family,'' he said. ''But we need to give people the raw data and facts.''

The plan for a public-relations campaign comes on the heels of plans to enter the legal system, again, with efforts to free Beach.

Centurion Ministries said it will file a District Court motion, in January, seeking a new trial for Beach, 45. Centurion executive James McCloskey said evidence gathered in the past year was not properly considered by the Board of Pardons and Parole before it denied Beach's request for clemency.

It was the board's second clemency denial in the Beach case. In addition, his conviction has been upheld through several appeals in state and federal courts.

Beach maintains that a confession he gave was coerced.

The Montana attorney general will respond to new motions if they are filed, spokeswoman Lynn Solomon said, but for now considers the Beach case ''finished.''
