Four young men have entered guilty pleas at their arraignment in 6th District Court on charges of having bombed a Mt. Pleasant home. They will appear before Judge Don V. Tibbs at the Sanpete County courthouse on Feb. 14 for sentencing.

Heath Cook, 18, Moroni; Jon L. Cook, 18, Fountain Green; Thomas M. Davis, 19, Wales; and Ricky R. Goble, 20, Mt. Pleasant, acting on the advice of their counsel, entered the guilty pleas to charges of having placed an acetylene bomb at the Mark Bezzant residence on the night of Oct. 31.The explosion blew out a basement window, damaged a chain-link fence and frightened the Bezzant family, who had been the objects of previous vandalism and harassment apparently directed at Mr. Bezzant, in his second year as principal of North Sanpete High School.

An investigation by city and federal officers resulted in the arrest and charge of the four with a third-degree felony and a class A misdemeanor.

Following the Oct. 31 incident, Bezzant submitted his resignation to the North Sanpete School District board of education. The board accepted the resignation "with regret" because of the circumstances under which it had been tendered and offered a $500 reward for the arrest and conviction of the bombers.

The board has not yet determined what disposition to make of the reward money, because several people were involved in the months-long investigation.

The Bezzant family is now living in Utah County.

Sentences could involve jail terms, fines or both, court officials said.
