What Happened to Tamir Rice?

Tamir Rice was a happy 12 year old simply playing with a toy gun in a park. He was reported through a 911 call in which the caller noted that he was most likely a juvenile and the gun was probably fake. However, after just a 2 second encounter Tamir Rice was dead after being shot twice by police. The man who killed Tamir ,Timothy Loehmann, was not convicted of any charges. Say his name.
