A teenager from Massachusetts, identified as Ian Fotheringham, was arrested over allegations of expressing a desire to carry out a school shooting but was later allowed by a judge to post bail and return home.

Fotheringham, 18, was detained on September 11 by the Falmouth Police Department, in collaboration with Massachusetts State Police detectives. Concerns regarding Fotheringham’s actions arose in August when investigators were alerted that he allegedly expressed intentions to “shoot up a school.” Though he did not specify any particular school, it was reported that he spoke of “refurbishing firearms in his room.”

Earlier in the month, elementary school safety monitors reported a “suspicious male” who appeared to be surveying the property. The man was identified as Fotheringham.

Following the tip in August, investigators visited Fotheringham’s home, where he consented to a room search, finding no weapons. However, a second search conducted after the property surveying incident revealed a substantial 3D printer capable of producing firearms.

In a search of Fotheringham’s phone, police discovered photographs related to the Columbine High School shooting. Cape and Islands Assistant District Attorney Tom Flanagan noted in court that these images, allegedly sourced from the dark web, depicted bloody victims and included the Columbine shooters.

Court documents obtained by local CBS affiliate WBZ stated that Fotheringham was also involved with a white supremacist group online.

The teenager faced charges for threatening to use a deadly weapon in a public building. Initially held without bail, he was given the opportunity for bail during his court appearance on Tuesday.

WBZ was in the courtroom for Fotheringham’s hearing, during which more details about his alleged threats and activities were presented by prosecutors and defense attorneys. According to WBZ’s reporting, Fotheringham had allegedly made threats against Falmouth High School, where he used to be a student, in October 2024.

Local ABC affiliate WCVB reported that Fotheringham’s defense attorney Krysten Condon has filed a motion to dismiss the charges. Condon told WCVB that Fotheringham has “not made any threats, nor has he harmed anyone. This is a case of exaggeration and speculation.”

In court, Condon said that Fotheringham was with his mother the day he was allegedly seen “casing” Teaticket Elementary School. She also noted that police “did not find any firearms” during their search, nor did they find clothing that matched what the man seen by school safety monitors was wearing.

A Barnstable District Court judge reduced Fotheringham’s bail to $2,500 on the conditions that he wear a GPS monitoring device and remain on house arrest while receiving mental health treatment. He is allowed to leave the home for legal and medicinal purposes. Fotheringham is scheduled to appear in court again on Oct. 6.
