A Texas Tech
University police officer was fatally shot Monday night, and a student has been arrested for the killing. The student, Hollis A. Daniels, is 19 years old and did not have his firearm registered with Texas Tech
, which the university requires under the state's campus carry law. Daniels was also likely running afoul of the law since he isn't 21 years old, another requirement, although there are exceptions for veterans and members of the military.
