Cameron D'Ambrosio, 18, an amateur rapper and Methuen High School student, admitted Wednesday to having written a post on his Facebook page that said, "[Expletive] a boston bominb wait till u see the [expletive] I do, I'ma be famous rapping, and beat every murder charge that comes across me!" [sic], according to court documents, the Boston Herald reported.
Police learned of the threats after a student alerted a school official, the Herald writes.
School Superintendant Judith Scannell said D'Ambrosio's threats weren't made against a specific person or the school, but alluded to general violence, according to the North Jefferson News.
"When we're just recovering from what occurred in Boston, to make a threat and use what occurred in Boston to enhance your threat, is extremely alarming for us," Methuen Police Chief Joseph Solomon said at a press conference after D'Ambrosio was apprehended.
D'Ambrosio pleaded not guilty in court on Thursday and could face 20 years in prison if convicted on one terrorism charge of making a bomb threat, the Herald notes.
Police seized a computer tower and an XBox 360 with a hard drive from D'Ambrosio's home as evidence in the case, according to the Boston Globe.
"I don't think he was intending to do anything," a neighbor of D'Ambrosio's told local NBC affiliate WHDH-TV. "He was just full of hatred at the time. I don't think he's smart enough to build a bomb, you know?"
A probable cause hearing on the terrorism charge will be held May 9, the North Jefferson News reported.
Two homemade bombs that went off at the Boston Marathon on April 15 killed three people and wounded more than 250. Boston Police recently announced they had arrested three more men who allegedly helped suspect Dzokhar Tsarnaev after the bombings occurred.
