(QUINCY)—A Quincy Junior High School student is under arrest after a threatening note was found in a girls restroom earlier this week. The investigation into several earlier threats continues. Quincy Public Schools Superintendant Lonnie Lemon says the district will not be able to discuss the specifics of Thursday’s arrest at this time.  Lemon says administrators would like to thank a parent and a junior high student who provided valuable information that led to the arrests. There is a reward for information leading to a conviction in the threats.
