SEARSPORT, Maine — One week after the horrific school shooting in Uvalde, Texas, a student at Searsport District Middle School was accused of pulling a fire alarm and making a series of threats that shook school officials and led to criminal charges being levied against him.The student, whose name has not been released, was charged with terrorizing and false public alarm after the May 31 incident. It’s at least the second time that Waldo County school districts have reacted to threats since the Texas shooting of 19 children and two teachers caused communities around the country to go on high alert.
