Tyler Mailloux sentenced for fatal hit-and-run in Berlin

Tyler Mailloux has been sentenced to 10 years for a hit-and-run crash that killed 14-year-old Gavin Knupp. However, he will only serve 18 months in prison, with the rest of his sentence suspended. The incident took place on July 11, 2022, in Berlin, Maryland. On March 19, 2025, Mailloux, who is 24 years old, was sentenced by retired Judge Brett R. Wilson. Mailloux was found guilty of not stopping his vehicle after the accident, which resulted in Knupp's death. Following his release, he will be on supervised probation for three years. The prosecution had asked for a longer sentence, suggesting that it was crucial to deter future hit-and-run incidents. State’s Attorney Kris Heiser expressed disappointment with the shorter sentence but acknowledged the importance of the proceedings for Knupp's family and friends. While Mailloux has been in custody since pleading guilty on February 25, 2025, he is required to complete a driver improvement program, attend a victim impact panel, and perform 400 hours of community service as part of his probation conditions.
