"My brother wasn't innocent in the whole thing. He was fighting on a city bus," Robert Rodgers, Bishop's half brother, said.
Rodgers says he and his brother decided to go to McCarthy's Sports Bar and Grill in Aurora to play pool. They hopped on an RTD bus, walked to the back of the bus and opened the windows.
"At one of the lights the bus driver stopped the bus, walked to the back and closed the window saying the A/C was on and they didn't needed to be open. We totally understood that," Rodgers said.
That's when Rodgers says another man on the bus starting calling them derogatory names.
"We didn't attack him. He was provoking us the entire time. My brother was killed for opening windows," Rodgers said. "This guy had been yelling at my brother the whole time. He saw me ring the bell. That's when he stood up and said 'I'll stab you.' I said, 'You are going to have to go through me first.'"
Rodgers says the three of them all started exchanging words. When the bus got to Chambers and Smoky Hill roads, all three got off the bus.
"They were still yelling at each other and I looked down and saw my hand ... my thumb was barely hanging on," Rodgers said.
Rodgers says he must have been stabbed on the bus and didn't realize it because everything was moving so fast.
Rodgers then ran into McCarthy's to get help not realizing at the time that his brother had been stabbed.
"Next thing I know, I am at the police station and they said the guy killed my brother," Rodgers said.
The third person involved, the man who had the knife, has not been charged.
According to Aurora Police Department, investigators are still looking at the bus surveillance tape and will determine if any charges will follow.
"He's was my only family in this town. He pushed me out of the way and he died defending me. I feel empty. He was my whole world. I'm going miss everything about him," Rodgers said.
The victim, Aaron Bishop, leaves behind a 10-year-old daughter. A memorial fund was set up in his name at all Wells Fargo banks.
