We are writing to update you on the investigation regarding the report of a potential threat to Curtis Middle School.

 Based on the police investigation to this point, we have determined that the circumstance surrounding the incident occurred several months ago, not recently as originally conveyed.  Prior to determining whether criminal charges are warranted the police will need to consider additional evidence.

Appropriate steps were taken by police and school personnel given the information that was initially received and erring on the side of caution.  As the investigation progressed, we developed confidence that there is no current threat nor does it appear students, staff or the community were in danger.  The safety of our students, and all Sudbury residents, is of utmost importance.

Please understand that there are confidentiality requirements when juveniles are involved and in also in relation to individual student information. The school administration is in the process of conducting their investigation and will take appropriate actions.   School administration is also working to provide support for all students that may have been impacted by the report.

We take all reports seriously and investigate fully before making determinations.  Please join us in encouraging students to speak up when something does not seem right.  We appreciate your patience, understanding, and support at this time.

We are confident there is no current threat nor were the means to carry out the alleged threat with a firearm. Our investigation continues to gather all information available. As the investigation progresses we will update as we are able but please understand juvenile matters are confidential by law. If anyone has information or knows of someone who may information please contact the police department at (978) 443-1042. We are proud of the student who passed on the threat to an administrator.

During our investigation the parents of the juvenile involved were cooperative and after consultation with detectives it was determined it would be best for the student to remain out of school. Please understand information as such cannot and would not ever be disseminated by school administration.


Thank you for your understanding regarding the report of a potential threat at Curtis middle school.  As communicated last evening, administration at Sudbury Public Schools received a report of a potential threat that was immediately referred to Sudbury police initiating an investigation.  Out of an abundance of caution, although the investigation had just been initiated, we communicated with families last night about the reported threat due to information that some students may be aware of the threat.


In providing an update, we are able to report this morning that the threat was reported to have been made by a student involving a firearm.  Sudbury Police were immediately notified initiating an investigation.  Parents were cooperative allowing us the opportunity to verify there was no access to any firearm.  Given the progress of the investigation at this point, we are confident no threat exists involving said investigation.  Although students and staff are safe, we will have a police presence to reassure students, parents, and staff. 


The Sudbury Public Schools administrative team will focus on reassuring students and will provide support for any student who may have knowledge of the reported threat.  If you would like the administration to check in with your child please be in contact with the administrators or counselors at school.  In addition to the police investigation, school administrators will take appropriate steps aligned with school safety and discipline policy. 


As always, the safety of our students and staff is our top priority.  Sudbury police and the SPS administrative team will continue to work together and will communicate further information if and when warranted.


We thank you for your patience.

Sudbury Police, in cooperation with Sudbury Public School staff, are in the midst of an active investigation surrounding a serious threat involving Curtis Middle School.  The investigation is in the very early stages but Dr. Wilson and I felt it important to notify parents given the seriousness of the threat.  As we learn more, a decision will be made as whether to cancel school but at this point that decision has not been made.  The safety of our students and staff is paramount.  As further information is developed we will update you while relating what steps we feel are appropriate to best ensure everyone’s safety.  We understand frustration regarding the limited information we are able to provide but we do not want to jeopardize the investigation.  Thank you for your patience and understanding.
