An unarmed college student at University of the Incarnate Word in Texas was killed by a campus police officer last Friday, and now the police are investigating the incident. The officer who fired the gun has been placed on administrative leave, but the family of the victim still has a lot of questions.

The 23-year-old communications arts major Robert Cameron Redus was pulled over for allegedly driving recklessly, according the police. After a “struggle” took place, the officer, Christopher Carter, fired six shots. The incident took place at an apartment complex not far from the school.

“I didn't hear him say anything like, 'Get down on your hands and knees,' you know? I didn't hear him say anything. He just started shooting,” one witness told KSAT.com.

Another witness told the San Antonio Express News that he heard Redus’ last words. “I heard (a man) say, 'Oh, you're gonna shoot me?' like sarcastic almost,” said Mohammad Haidarasl.

The university says that Carter had an extensive law enforcement background and that he worked for the school for a few years. But documents published by the San Antonio Express News show that he worked for the Texas university for two and a half years after holding nine different jobs at eight separate law enforcement agencies.
