Tonight, what Police Investigators found. Abcs Ron Claiborne with the details. Reporter the sheriffs report describes the dramatic moments leading up to the cleveland Police Officer fatally shooting tamir rice last november. Several witnesses, including Police Officers and an fbi agent who arrived at the scene just after the shooting, told investigators officer timothy loehmann, who fired the shots, said he had warned tamir, but the boy went for a weapon. Then, he shot him. He gave me no choice, one witness, an offduty Police Officer, said loehmann told him. He reached for the gun and there was nothing i could do. But the report said according to witness interviews, it is unclear whether officer loehmann issued commands from inside the patrol car before discharging his weapon. The video shows loehmann firing at the boy within two seconds of getting out of the patrol car. Tamir lay on the ground for three to four minutes before the fbi agent began to help him. It turned out tamir had a nonlethal pellet gun. Investigators said the boy who had given it to him had cautioned him to be careful because it looked like a real gun. Loehmann and his partner Frank Garmback declined to be interviewed by investigators. And this report comes just two days after a judge ruled there was enough evidence to charge officer loehmann with murder, and his partner with negligent homicide. That was only an advisory ruling, not binding on prosecutors. The Prosecutors Office says it will take the case now to a grand jury in a matter of weeks which, tom will then decide whether to file criminal charges against those Police Officers.
