Police seek public's help in identifying pedestrian injured in hit-and-run near 16th Avenue and A Street in Anchorage, Alaska

"The pedestrian was unconscious in this case, and we have not been able to speak with him," Castro said. "The other part of this is that we don't know who he is."

Castro urged citizens with word on the pedestrian's identity, or anyone who knows someone who was walking last night in the area of the collision but hasn't returned, to call police at 907-786-8900.
