Portland State University student Kat Caputo was talking to a friend by the light-rail station when she heard a commotion and turned around.

She says she saw two women lying on the sidewalk and another leaning against a brick wall.

Others were shouting that a car had jumped the curb, struck the women and sped away. Caputo says one of the women had a huge bruise on her back and screamed when the paramedics touched it.

Caputo says she was shaken because she was running late and might have been hit herself otherwise.

More than an hour after the incident, a green sweater, a pair of sneakers, a pink slipper and one black bike glove lay scattered on the sidewalk near a small splash of blood.
