OXFORD – With the arrest of four students and two parents in the last few weeks, the Oxford Academy School District has seen a sharp increase in the number of crimes taking place on school property.

Between March 20 and April 3, two of the students, a 16 and 17-year-old, were charged with harassment over fighting. Another 16-year-old was charged with harassment for allegedly bullying another student, and a 13-year-old middle school student was charged with unlawful possession of marijuana.

In the unconnected incidents, each student was also suspended from class for five days, according to a statement released by the Oxford Police Department.

Two parents were also arrested, 51-year-old Susan J. Mackney and 55-year-old Alexis A. Kaminski, both of Oxford. Kaminski was charged with second degree harassment after he allegedly threatened a teacher with physical violence. Mackney was arrested for making threats to a teacher and charged with second degree harassment and second degree aggravated harassment. Mackney allegedly exchanged numerous e-mails with a teacher since February which initially began as a dialogue over a complaint with the school but became increasingly confrontational.

The alleged threats took place on April 3, the same day that the nationally reported shooting rampage in Binghamton left 14 people dead.

Police said that neither parent made direct threats against a single teacher, but claimed that the two had alluded to the use firearms.
