According to the Rainer Valley KOMO blog:
A 13-year-old girl using her cell phone stepped in front of a moving light rail train at the station at MLK and Othello and was hit on Friday afternoon.
The incident happened at around 3:45 p.m. The girl was not paying attention and didn’t see the train coming as it was pulling into the northbound station. She suffered cuts to the face, but no other serious injuries. She was taken to a hospital for treatment. It isn’t known if she was talking or texting on her phone when the collision happened.
After some delays, service is now restored.
