Did his bus transfer work on the ambulance?

Could've been the groaning, could've been the bleeding--the article doesn't say.

But passengers on a Metro bus rolling through Kent Monday afternoon somehow noticed that a fellow rider had been stabbed.

The boy had apparently gotten into an argument with his 16-year-old girlfriend shortly before he got on the bus near the intersection of Fourth Avenue and West James Street in downtown Kent. Both teenagers are Kent residents.

Police learned the girl had cuts on her face from when the boy punched her.

While she was on the ground, she drew a small knife and stabbed him. He ran away and she called for help on her cell phone.

Firefighters and King County Medic One paramedics met the bus at a stop on the West Valley Highway near South 190th Street.

A firefighter said the youth's wounds were serious, but not life-threatening. He was treated at the bus stop and then taken to a hospital.

The boy, police say, was the aggressor, and is under investigation for domestic abuse.
