The Multnomah County District Attorney’s office announced Wednesday morning a grand jury returned a four-count indictment for a driver accused of hitting and killing an 11-year-old boy walking to school.  

The driver, 26-year-old Garrett Bergquist, is accused of running a red light last week and killing Luis Medina, a sixth grader who was walking to Dexter McCarty Middle School in Gresham.  

An Oregon State Police Trooper dispatched to the scene determined Berquist was driving impaired by “central nervous system depressants” and narcotic pain relievers.  

Bergquist is charged with manslaughter in the first and second degree, driving under the influence of intoxicants and reckless driving.  

He will be arraigned in Multnomah County Circuit Court Wednesday.
