Federal court convicts Nebraska man of sexually assaulting child on Indian reservation

OMAHA, Neb. (WOWT) – The U.S. Attorney’s Office for the District of Nebraska reported three sentencing updates Friday involving a sex offender, a drug offender and a weapons violation.

U.S. Attorney Jan Sharp’s office in Omaha reminds the public that there is no parole in the federal system.

Warren Lee Mackey, 68, of Niobrara, was sentenced Thursday to 30 years in prison for aggravated child sex abuse and 10 years for child sex abuse on the Santee Sioux Nation Indian Reservation. The penalties must run concurrently. An 11-year-old girl said Mackey touched her in private areas. He claimed he was sleeping when it happened, dreaming of a grown woman and not realizing what he was doing. He was found guilty by a jury in October 2021 and will be on probation for five years after his conviction. The case was investigated by the FBI as part of Project Safe Childhood, the statement said.

Chad Carlson, 44, of Axtell, was sentenced Thursday to 15 years and eight months in federal prison, plus five years of probation, for conspiring to distribute at least 500 grams of methamphetamine. He was convicted of selling methamphetamine to several central Nebraska communities from 2015 to 2019 and was caught selling to a confidential informant in October 2018. The case was the subject of a investigation by the Central Nebraska Drug and Safe Streets Task Force, according to the release.

Kaleb Slayer, 24, of North Platte, was sentenced to 15 months in prison on Wednesday, with three years of probation thereafter, for being a felon in possession of ammunition. Slaymaker has a previous conviction for attempted burglary. Authorities executing a search warrant said they found a small amount of methamphetamine, paraphernalia containing residue, and 90 .22 long shotgun shells in his bedroom dresser. The case was investigated by the North Platte Police Department as part of Project Safe Neighborhoods.
