A former Colorado sheriff’s deputy convicted of killing a 22-year-old man in distress who called 911 for help has been sentenced to three years in prison, the maximum sentence allowed.

In February, jurors found Andrew Buen guilty of criminally negligent homicide in the 2022 death of Christian Glass. Prosecutors alleged that Buen needlessly escalated a standoff with Glass, who showed signs of a mental health crisis and refused orders to get out of his SUV near Silver Plume, a small, former mining town along Interstate 70 in the Rocky Mountains west of Denver.

His parents and the agencies involved reached a $19 million settlement that also made changes to how officers are trained to respond to people in mental health crises.
