Amy Bishop-Anderson made her first appearance in District Judge Ruth Ann Hall's Huntsville courtroom since her Feb. 12 arrest on charges of killing her fellow professors at the University of Alabama, Huntsville, WAAY-TV, Huntsville, reported.
Huntsville Police Department homicide investigator Charles Gray testified at Tuesday's hearing the faculty members who died had been sitting closest to Bishop-Anderson at the meeting and all three were shot in the head at point blank range.
Gray said the 9mm gun had a magazine with 15 rounds, six of which were fired before the weapon jammed. He said police later found a fully loaded 15-round magazine in a bag Bishop-Anderson left in the conference room, WAAY reported.
Three other professors were wounded in the shooting rampage that took place at the end of a faculty meeting. Anderson has been charged with capital murder and three counts of attempted murder.
Gray said investigators -- with help from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives -- traced the weapon to a New Hampshire man who told ATF agents he sold the gun to James Anderson in 1989. Anderson lived in Massachusetts at the time, where gun laws were stricter than in New Hampshire, WAAY reported.
