A 19-year-old man has pleaded guilty to threatening to bomb a place of assembly after admitting he posted a string of violent messages targeting high schools in Loudoun County, Arlington and beyond. Alexander Blake Berg, who was living in a group home at the time, entered the plea as part of a deal in which prosecutors dropped a separate charge against him, according to court proceedings.
The case traces back to social media posts Berg made under the name Mr. Pimp, according to Loudoun Now. Among the messages attributed to him were the lines “I can’t wait to bomb this stupid high school,” “I am going to bomb this school ok,” “Man I am really going to have fun bombing this high school,” and “F—k I hope everyone dies at that high school I might kill everyone myself.” Loudoun Now reports detectives linked the posts to Berg and that the Loudoun County Sheriff's Office was told he had made Twitter posts threatening several Virginia schools, including Broad Run High School and Woodgrove High School. Berg also threatened a school in Virginia Beach, per the same outlet.
Separately, according to court records cited by ARLnow.com, Berg made a bomb threat against Yorktown High School in Arlington on the social platform X in response to a post from Arlington's GOP that complained about school flag protocols. Criminal complaint documents cited by the outlet indicate Berg later admitted to law enforcement officers that he posted the bomb threats against the two Loudoun County schools because he was bored and knew his actions amounted to a felony.
An Overnight Search and a Multi-County Arrest
Bomb squad personnel checked the threatened schools as a precaution and responded to each one named in the posts, per Loudoun Now. In Arlington, police officers inspected Yorktown High School around 3 a.m. on September 18, 2025, ultimately determining the online threat was non-credible and allowing school to start on schedule with extra police presence on campus, ARLnow.com's report on the court records notes.
Berg, now 19, was arrested in September 2025 following the investigation. He was charged in Arlington County with two felonies — making a bomb threat and threatening death on school property — exposing him to as much as 15 years in prison in that jurisdiction alone, according to the same court records reviewed by ARLnow.com. Proceedings against him remain ongoing in Arlington County even as the Loudoun case moves toward sentencing.
Felony Exposure Tied to His Age
Threatening to bomb a place of assembly is a Class 5 felony under Virginia law, carrying a sentence of one to 10 years in prison, according to Loudoun Now's account of the plea. Under Virginia Code § 18.2-83, that same conduct by someone under 18 is instead classified as a Class 1 misdemeanor — meaning Berg's status as an adult at the time of the posts is central to the felony exposure he now faces, per the Virginia General Assembly Legislative Information System. Separately, Virginia Code § 18.2-60 makes it a Class 6 felony, punishable by up to five years, to knowingly communicate an electronic or written threat to kill or harm someone on school grounds, per state law.
Virginia's venue statute also explains why Berg could be prosecuted in more than one jurisdiction at once. Code § 18.2-83 permits bomb threat offenses to be prosecuted either where the communication originated or where it was received, allowing both Loudoun and Arlington counties to pursue charges against him independently even though he resided in Henrico County.
Background and What Comes Next
Berg received psychiatric treatment throughout his childhood, according to Loudoun Now's reporting. He is scheduled to be sentenced in November 2026, with a courtroom image from the case credited to Douglas Graham depicting the jury box inside a Loudoun County courtroom.
Virginia has required public school divisions to run dedicated threat assessment teams since 2013, when it became the first state in the nation to mandate the practice, according to the Virginia Department of Criminal Justice Services. The agency's 2024 School Safety Survey found that 76 percent of surveyed public schools statewide reported receiving at least one threatening communication, such as a bomb threat, during the school year. Even so, a multi-school evaluation conducted by University of Virginia researchers found that only 5 percent of student threat assessments result in criminal charges and just 1 percent lead to arrest, according to the Comprehensive School Threat Assessment Guidelines — a statistic that underscores how unusual Berg's felony prosecution is compared with the vast majority of school threat cases nationwide.
