Anderson was last seen leaving a QuikTrip in North Kansas City early January 15 while driving a black 2014 Ford Focus, according to Kansas City police.
Her boyfriend, Pete Sanchez, told CNN that Anderson was driving home from work at a local club and was pulled over by police.
Anderson's disappearance sparked weeks of searching until last week, when that vehicle was pulled from the Missouri River in Parkville, Missouri. The body inside was identified as that of Anderson.
Police said there is no indication of foul play.
The window was down and her seat belt was off, KCTV reports.
