BUFFALO, N.Y. (AP) - A person familiar with the investigation tells The Associated Press that police in Buffalo, N.Y., are looking for a trauma surgeon in connection with the fatal shooting of a 33-year-old woman. The person says police are looking for Timothy Jorden Jr. The person spoke on condition of anonymity because the investigation is continuing. Police haven't identified any suspect in the shooting Wednesday morning at the Erie County Medical Center. The slain woman has not been identified by police.

The hospital was locked down for more than four hours. (Copyright 2012 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.)
