A variety of electronics were seized from the home of a South Burlington High School student suspected of sending repeated death threats to several students and teachers.

The disclosure comes after Local 22 & Local 44 petitioned the U.S. Attorney’s Office to unseal additional paperwork in the case against 18-year-old Josiah Leach.

Judge Christina Reiss signed off on the search warrant at 4:45 Friday afternoon. It was executed later that day. By Friday night, Leach was in custody.

According to federal documents made public Tuesday, law enforcement seized several items from Leach’s Farrell Street home, including a Dell Latitude laptop, two HP laptops, a Galaxy Note cell phone, a ZTE phone, three SD cards, a thumb drive, an XBox One, and an ICS Infinity computer.

A search warrant application, also made public Tuesday, shows the FBI asked to seize: ‘any and all firearms, explosives, or components thereof, or other weapons including knives; records and information relating to the physical layout of South Burlington High School or any other South Burlington, Vermont school; records and information related to large scale attacks on individuals, planning and executive of such attacks, and/or of the individual recipients of the threat emails of individuals listed on the ‘Murder List.’

Police say Leach, a senior, made a series of threats against specific teachers and students at South Burlington High School. Officials say the threats triggered three lockdowns and canceled classes on Friday. Police say the threats were made via email, telephone and Facebook.

According to a motion for detention filed Monday, Leach admitted to sending at least one of the threatening emails.

“During the interview, moreover, Leach also claimed that he did not intend to hurt anyone,” read the sworn affidavit from Acting U.S. Attorney Eugenia Cowles and Assistant U.S. Attorney Michael Drescher. “The veracity of that claim is dubious, however, in light of other self-serving lies he made during the same interview.”

Leach was arrested at his home in South Burlington Friday evening. He’s been federally charged with knowingly transmitting threatening communications in interstate commerce.

Leach made his initial court appearance at U.S. District Court in Burlington Monday. A federal judge ordered him held until his next court hearing—which is scheduled for Thursday morning.

Leach is being represented by Assistant Federal Public Defender Elizabeth Quinn. On Tuesday, the Federal Public Defender’s Office told Local 22 & Local 44 she would not be making any comments on the case.
