A 23-year-old South Korean man was sentenced from 12 to 30 years in prison for driving drunk and causing a high-speed crash that killed two teen girls.

Seong Lee pleaded guilty in February to causing the crash that killed 17-year-old Kamesha J’Nyah Gilmore and 18-year-old Gabriell Rene Thomas in March 2015.

Family members of the two girls gave emotional testimony.

“Losing Gabrielle has basically destroyed me inside,” said Emma Woods, Gabrielle’s grandmother.  “I think about her daily. I carry her picture; I talk to her, I try to talk to her on her cell phone just to hear her voice, but it’s not there. He took her away from us.”

Lee cried during the sentencing as his attorney asked for leniency saying that Lee accepted responsibility and needed substance abuse treatment.

Police said Lee’s blood-alcohol level was twice the legal limit when the Mercedes he was driving slammed at 117 mph into a Nissan Versa making a U-turn on Boulder Highway.

Lee was awaiting trial at the time on a misdemeanor drunk driving charge stemming from a July 2014 arrest.
