Kansas City, Mo. ? A man who said he was “hanging out with the wrong crowd” has been sentenced to 30 years in prison for a murder that was caught on surveillance tape outside a liquor store.

Rubin Turner, 61, was shot in the head and killed in November 1999 in the liquor store parking lot. The grainy surveillance tape played in Jackson County Circuit Court on Friday showed the gunman coolly walk away after the shooting.

“It was murder conducted as a matter of business,” Judge John Torrence said in sentencing David W. Bates on his convictions for second-degree murder and armed criminal action. “Planned, intentional murder.”

Bates, who pleaded guilty to the charges in October, was a member of a Los Angeles gang involved in drug sales in the Kansas City area. After his arrest in Los Angeles, he told Kansas City police that a drug boss ordered the murder because police had caught Turner at the airport with more than $80,000 in drug money.

But two Kansas City police officers testified at the sentencing that Bates never received an order to kill Turner – doing it, rather, to curry favor with his boss.

Defense attorney Todd Schultz said Bates was raised without a father and “filled that void with the wrong people.” Schultz, who asked for a sentence of no more than 15 years, said Bates killed because he feared that otherwise the drug boss would kill him.

Bates, saying he was sorry, said, “My life was in danger. I was hanging out with the wrong crowd.”
