LINCOLN, Neb. (AP) — A Nebraska man and woman have been sentenced to federal prison for distributing methamphetamine.

43-year-old Jose Ulloa has been sentenced to 21 years and 10 months in prison. Forty-seven-year-old Diane Holbrook has been sentenced to 10 years and 10 months.

Prosecutors say the pair distributed at least 18 ounces of meth in the Lincoln area between January 2012 and February 2014. Ulloa sold meth to an undercover officer in June and July of 2013.

The relationship between Ulloa and Holbrook is unclear.
