A fight broke out in the parking lot of Trinity Episcopal Church just before 5:00 p.m. Tuesday.  Apparently Patrick McKinley Mills, 20, of Bend and several other men began arguing while waiting to be served food at the church.  They began physically fighting. At one point one person drew a knife. Mills and another man began struggling over possession of the knife. Another man then head-butted Mills, causing an injury to him, but not from the knife.  The assailant fled the scene. When Bend Police and Bend Fire arrive on the scene, they bandaged Mills head and took him to St. Charles for further evaluation.  There were no charges or arrests at this point in the investigation. If you have any information, contact Bend Police.
