NORFOLK, Neb. -- A Norfolk woman, the fourth person in a drug conspiracy, was sentenced to 10 years in prison on Thursday. 

The U.S. Attorney said that 51-year-old Karina Rae Dieter of Norfolk was sentenced on Thursday in federal court in Omaha to 120 months in prison for her participation in a methamphetamine conspiracy.

The Chief U.S. District Judge sentenced Dieter to 10 years in prison, and after her release, she will begin a four-year term of supervised release. There is no parole in the federal system. 

Court documents said that in May 2020, the Holt County Sheriff's Office, Nebraska State Patrol and the United States Postal Inspection Service began investigating a meth drug trafficking organization based out of the Norfolk area. 

As part of the investigation, it was found that Katherine Tacheira was sending packages from California to recipients in Norfolk.

Dieter was found to have received 198 grams of meth from the packages. When she was arrested on the federal warrant, Dieter was in possession of 93 grams of pure meth.

In addition to Dieter, Dallas Rhinehart, and Lindsey Rokahr were also found to have received packages of meth from Tacheira.

Tacheira was sentenced on May 17, 2023, to 120 months in prison.

Rhinehart was sentenced on March 13, 2023, to 130 months in prison.

Rokahr has entered a guilty plea to the conspiracy and is set for sentencing on Aug. 4, 2023.
