HOULTON — A Maine judge expects to rule next month on a motion by attorneys seeking to suppress a young man’s confession to killing two men and a 10-year-old boy in Amity.

Thayne Ormsby’s attorneys made their case during a hearing Thursday in Aroostook County Superior Court. Attorneys will submit written materials before Justice E. Allen Hunter rules.

Ormsby is charged with killing 55-year-old Jeffrey Ryan, his 10-year-old son Jesse and 30-year-old Jason Dehahn at Ryan’s home on June 22, 2010. Ormsby, who was 20 at the time, is being held without bail.

Police, who say Ormsby gave his statements voluntarily, revealed during Thursday’s hearing that the three were killed with a combat-style knife. The Bangor Daily News says police had not previously revealed the weapon or whether it had been recovered.
