Ed Colfax was a police officer in Easter, Pennsylvania.
Sam and Dean go to question Ed after his partner and another police officer are killed in strange ways. When they find him, he is in full uniform and calmly scratching the faces off of all the photographs in his home. They question him and learn that the two dead police officers and Ed have something in common: "a kid with no face and a planted gun" named Christopher Birch. Ed believes that they are each suffering divine retribution for their part in Christopher's murder. Before Sam and Dean can learn anything else, Ed collapses, dead. Sam removes Ed's police hat and finds a hole in the top of his head from which locusts emerge.
Ed was killed by Aaron Birch, Christopher's brother, using the Staff of Moses to inflict him with the plague of locusts. His partner was liquified, his meat, bones, and other tissues changed to blood, and the other police officer was so covered in boils, inside and out, that his airway was blocked and he asphyxiated.
Unlike the other officers involved in the murder of Christopher Birch, Colfax was deeply bothered by their actions, contacting Toby Gray after the death of his partner out of fear that they were being targeted for their actions.
After the deaths of his two friends, Colfax went insane, scratching out the faces of every picture in his house and displaying erratic and often distant behavior, at one point staring blankly at a bottle of tipped-over alcohol before coming back to himself and putting it upright like nothing had ever happened. Colfax showed a belief that he and his friends deserved what was coming to them for their actions and didn't notice the locusts eating through his head despite his head being itchy until moments before his death when his bleeding head was pointed out to him. This state of insanity appeared to have been brought on by a combination of guilt, the brutal deaths of his friends and all of the brain damage the locusts were causing before they killed him.
