More Time Behind Bars for Geovanny Villalba-Aleman

In a dramatic turn of events, Geovanny Villalba-Aleman, convicted for a shocking stabbing spree at the University of Waterloo, will now serve a longer prison sentence. Originally sentenced to 11 years in March for attacking three individuals—including two students and a professor—Villalba-Aleman's time behind bars has been recalibrated due to a judge's mistake.

The Gruesome Attack and Initial Sentencing

Villalba-Aleman was found guilty of two counts of aggravated assault, one count of assault causing bodily harm, and one count of assault with a weapon. His horrific act involved entering a gender studies class and attacking his victims with a knife. While he faced a terrorism charge, it was dismissed by the judge, who stated that his ideologies were too erratic to be classified as an ideology.

A Judicial Error Uncovered

During a recent court proceeding, Justice Frances Brennan acknowledged that she had made an "unintentional" mathematical error when calculating Villalba-Aleman's credit for time served prior to his sentencing. Initially, he was credited for serving 1,254 days when he had actually spent only 627 days in jail.

Calculating Custody Credit: A Closer Look

The judge explained how this significant error effectively gave Villalba-Aleman a 2-to-1 credit for pre-sentence custody instead of the standard 1.5-to-1 ratio. This means he was edged closer to an earlier release than he should have been.

The Implications of the Revision

After the correction, his recalculated time served resulted in a total of 3,074 days—approximately eight years and four months in prison from the date of his original sentencing hearing. The defense argued that this revised judgment felt harsh, while the Crown maintained that the change was necessary to uphold judicial integrity.

Reactions from Legal Experts

Boris Bytensky, president of the Criminal Lawyers’ Association of Ontario, commented on the situation, emphasizing that human errors occur within the criminal justice system. Bytensky supported the judge's decision to amend the sentence, as she had initially made clear her intention on the credit calculation.

Moving Forward: A Lesson Learned

In light of this incident, Justice Brennan stated that she will no longer calculate pre-sentence custody independently but will involve other parties to avoid such errors in the future.
