KANSAS CITY, KS—A Kansas City man was sentenced Thursday to life in prison in a federal drug trafficking case, U.S. Attorney Barry Grissom said.

Christopher Craig, 32, Kansas City, Mo., pleaded guilty to one count of conspiracy to distribute cocaine, crack cocaine and marijuana, and two counts of using a phone in furtherance of drug trafficking. He admitted that he was part of a drug trafficking ring that operated from January 2006 to December 2012 in Kansas City, Kan.

Prosecutors argued for a longer sentence on the grounds that Craig planned and participated in an attempted robbery on Aug. 14, 2012, that resulted in the shooting death of one of the robbers. Officers were called to Research Medical Center when a shooting victim was dropped off at the emergency room entrance. The victim died of three gunshot wounds to his upper body.

Investigators learned that Craig had planned the robbery. He had taken the victim and another man to a south Kansas City location where a large sum of money and drugs were kept. During the robbery, the target of the robbery shot the victim. Craig was a member of the MOB street gang.

Grissom commended the Kansas City, Kan., Police Department, the Kansas City, Mo., Career Criminal Squad, the FBI, Assistant U.S. Attorney Sheri McCracken and Special Assistant U.S. Attorney Trent Krug for their work on the case.
