Authorities in Imperial Beach, California, arrested 18-year-old Kristoffer Von Hassel on Tuesday in connection with multiple incidents of antisemitic graffiti targeting local homes, according to the San Diego County Sheriff’s Office.
Core developments
- Arrest confirmed: Von Hassel was taken into custody around 3 a.m. near an alley where vandalism had occurred, following surveillance footage that identified him as a suspect.
- Charges filed: He faces vandalism and civil rights violation charges, with authorities alleging the graffiti was motivated by hate.
Incident timeline and evidence
On September 13, deputies responded to reports of antisemitic graffiti—including swastikas and other symbols—drawn in black permanent marker on two homes in Imperial Beach. A second incident occurred at one of the same properties on September 19, prompting increased patrols and a review of nearby surveillance footage.
Investigators located Von Hassel in the alley behind one of the vandalized homes, where they also found a handheld electronic device capable of analyzing wireless signals, which could interact with garage doors and other systems. The device was recovered as evidence, though its specific role in the investigation has not been disclosed.
Impact on victims
Residents, including Sandy Brillhart, whose home was targeted, reported feeling unsafe following the incidents. Brillhart stated she no longer feels secure in her home or at the beach, adding that the vandalism initially appeared to be typical mischief before the antisemitic symbols were recognized.
Background on the suspect
Von Hassel gained attention in 2014 at age 5 after exposing a security flaw in his father’s Xbox console, earning media labels such as the “world’s youngest hacker.” Microsoft subsequently added him to its list of security researchers. His parents, in a statement to ABC10 News, denied any knowledge of the alleged vandalism and stated the family does not hold hateful beliefs.
