BOGOTA, Colombia (AP) - Colombian police say the son of a warlord extradited to the U.S. on drug charges has been murdered.

Authorities say unidentified assailants shot and killed 32-year-old Vladimir Vanoy on Sunday at the gate to his condominium outside Bogota.

Ramiro "Cuco" Vanoy is Validmir’s father. He was extradited to the United States in May with 13 other far-right warlords. A Miami judge earlier this month sentenced him to 24 years in prison on drug-trafficking charges.

After the sentencing, the newspaper El Tiempo quoted one of his lawyers as saying he would no longer cooperate with investigations into crimes associated with far-right militias.
