The chidren belong to Fort Colville Elementary school in northeast Washington.
Authorities discovered the plan when a fourth-grader saw one of the boys playing with a knife aboard a school bus and told a school employee what he had seen.
A search of the 10-year-old's backpack found a knife, a .45-caliber semi-automatic pistol and a full ammunition magazine, court records showed.
School counselor Debbie Rogers testified Friday about her interview with the 11-year-old the day the gun and knife were discovered. The boy said he was planning to stab the girl to death because she was “really annoying” and the second boy was to point the gun at anyone who tried to intervene, Rogers said.
