A 36-year-old Tucson man has been sentenced to nearly 28 years in prison in a racketeering case, federal prosecutors say.
David Kapone Williams, an admitted Tucson street gang member, was sentenced Sept. 16 after pleading guilty to conspiracy to participate in a pattern of racketeering activity, the U.S. Attorney's Office in Tucson said Monday in a news release.
U.S. District Judge James A. Soto sentenced Williams to 335 months in prison, followed by five years of supervised release.
Prosecutors say Williams was a member of a street gang involved in a pattern of racketeering activity, including narcotics trafficking, possessing firearms, witness intimidation, and committing violent crimes, including murder.
On May 15, 2015, along with other gang members, Williams killed a rival gang member in the parking lot of a hotel near the airport. He also participated in a separate October 2014 homicide, the release said.
