A 76-year-old man who went into hiding following a 1982 bombing and allegedly assumed the identity of his dead college classmate was arrested this month at his home in New Mexico after a standoff with law enforcement.

Stephen Craig Campbell is accused of using the name of University of Arkansas classmate Walter Lee Coffman, who died in a car accident months after graduating.

Stephen Craig Campbell’s decades as a fugitive ended in a dramatic arrest in which he “allegedly greeted law enforcement armed with a scoped rifle, positioning himself in an elevated, partially concealed spot,” the U.S. Attorney’s Office for the District of New Mexico said in a Feb. 26 news release.
