HOUSTON -

A man will spend the next 15 years in prison for causing a crash that killed a 16-year Harris County Sheriff’s Office veteran.

The sheriff’s office says Andres Muños-Muños, 23, was driving drunk when his vehicle hit a truck driven by Sgt. Dwayne Polk on May 19, 2013. Sgt. Polk was driving home from an off-duty job at the time of the crash.

Muños-Muños pleaded guilty to intoxication manslaughter.

During Muños-Muños' sentencing hearing Wednesday, Polk's 11-year-old son read a statement to the judge: "I am asking for justice for my dad, that's why I want the maximum for someone who was driving drunk. I miss my dad very much. He will not be here anymore to take me to school, see me play football, take me on a vacation or attend my graduation. If the man responsible for my dad's death gets what he deserves it will give me some relief. He has stolen my joy forever, I wish my dad was here. I just want justice for my dad."

Sheriff Adrian Garcia was in the courtroom for today's hearing.

Muños-Muños, who had previously been arrested for driving while intoxicated in 2012, was sentenced Wednesday to 15 years in prison.
