OMAHA, Neb. (AP) — The Nebraska Supreme Court has upheld the manslaughter, pandering and weapons convictions of a man serving time for killing a woman in Omaha, but has ordered he be resentenced.

The high court on Friday said a Douglas County district judge erred when he sentenced Reginald Briggs to 20 years for manslaughter and 10 years for possession of a weapon by a prohibited person. The high court says state law requires a sentenced that encompasses a minimum and maximum range for those counts. The high court also ruled that Briggs was not entitled to more than two years’ credit for time served on a separate pandering conviction, because he was already serving prison time for the manslaughter case while awaiting trial on the pandering charge.

Police say Briggs shot 31-year-old Teresa Longo to death in September 2015. Investigators say Longo was homeless when Briggs offered her a place to stay in exchange for working for him as a prostitute.
