A Virginia man has been sentenced to more than eight years in prison for his role in a violent, multi-million dollar jewelry theft ring.

Federal prosecutors say 34-year-old Luis Carlos Muchado was sentenced Friday in U.S. District Court in Norfolk for the ring that operated out of Richmond.

According to court documents, co-defendant 37-year-old Alexander Cuadros-Garcia of Colombia led the group that stole more than $4.6 million in jewelry from victims in Virginia and at least four other states including New York, New Jersey, North Carolina and Maryland.

Most of the robberies involved damaging car windows and threatening victims at knife-point.

Cuadros-Garcia and Muchado were charged along with six other members of ring in March 2012.

Prosecutors say Muchado pleaded guilty in April to racketeering charges. Cuadros-Garcia previously pleaded guilty for his role and will be sentenced in October.
