CENTER CITY, Minn. (AP) — A Minnesota man has been sentenced to just over 13 years in prison for providing the cocaine that killed his on-again, off-again girlfriend.

Aaron Schnagl was sentenced Friday in Chisago County District Court. He was convicted in February of third-degree murder but acquitted of concealing the body of Danielle Jelinek.

Jelinek was missing for five months before her body was found in a slough near Schnagl's home in Chisago Lake Township in May 2013. She disappeared in December 2012. Authorities soon named Schnagl as a person of interest.

Prosecutors say the 27-year-old Oakdale woman died after a night of drinking, drugs and sex at Schnagl's house.

Schnagl admitted at trial that he was a drug dealer. When he was convicted, he was already serving time on a previous drug conviction.
