(CBS/AP) MOBILE, Ala. - Students are planning a demonstration to protest a deadly police shooting of a freshman at the University of South Alabama.
Organizers of the Wednesday protest say a campus police officer who shot and killed 18-year-old Gil Collar of Wetumpka early Saturday shouldn't have used deadly force.
Authorities say Collar had taken LSD and was threatening the officer. Critics including organizer Jonathan Ark say the officer should have done something else to stop the 5-foot-7 freshman.
Mobile County Sheriff Sam Cochran says the officer who shot Collar was armed only with a gun - and not a stun gun, pepper spray or baton.
A prosecutor says grand jurors will review the shooting and alleged drug involvement for possible charges, although it's unclear when.
Investigators are still trying to determine who provided Collar with LSD and could charge that person in Collar's death, said Mobile County Sheriff Sam Cochran.
"If a death results from an illegal action that you take then that person could have illegal charges against them," Cochran said, according to CBS affiliate WKRG.
