The Nova Scotia Court of Appeal has acquitted Brandon Klayme after an overlooked underscore in a Kik username was found to have directed investigators to the wrong person, according to Ars Technica. Klayme had already served an 18-month prison term.

The case began with a 2018 investigation in Wisconsin. A forensic examination of a 12-year-old girl’s phone found 125 Kik messages with an adult using the name `fus__ro_dah`, with two underscores after “fus.” When the Dane County Sheriff’s Department sought subscriber information from Kik, however, its subpoena named `fus_ro_dah`, using only one underscore.

Kik’s response to that different username supplied an email address belonging to Klayme. Google records connected the email to an internet address in Canada, and the investigation was passed to Halifax Regional Police. The local provider Bell Aliant then associated the internet address with Klayme’s residence.

Police searched phones and laptops taken from his bedroom, but Ars reported that the devices produced no evidence related to the alleged offence. Nothing on them connected Klayme to the girl, no intimate images were found, and investigators could not establish that he had accessed Kik during the relevant period. He was nevertheless arrested in 2020 and faced three child-sex-abuse charges.

Klayme was convicted after a 2023 trial and sentenced the following year. The discrepancy between the two usernames was not identified at trial. It emerged only during later work on his appeal, despite the relevant information having been available earlier. Prosecutors reviewed the issue and agreed that the appeal should be allowed.

The Court of Appeal overturned the conviction and vacated the remaining probation, stating that Klayme was factually innocent and should not have been charged. The court also said a correct investigation would have pointed toward an individual named Jay whose internet address appeared to be in California, Ars reported.

The record described by Ars shows how the initial data request shaped every later step. A request tied the wrong username to an email account; that account led to an internet address; and that address led Canadian officers to Klayme’s home. The complete absence of incriminating material on his devices did not stop the case from proceeding through trial and imprisonment.

The appeal decision resolves Klayme’s criminal case, but the report said there was no confirmed explanation for why the username mismatch escaped detection by investigators, prosecutors and the defence. The outcome leaves a documented example of how a one-character identifier error can persist across borders and through multiple stages of a justice system.
