The arrest comes after the MU Police Department (MUPD) was called to a welfare check at Hudson Hall, a dorm building on the university's campus, Tuesday around 5:30 p.m.MU spokesperson Christian Basi said the welfare check was for a male student, and court documents say the mother of the student made the request.She gave officers consent to search the home and backyard, where they found human remains in a fire pit, court documents said, noting the body was "smoldering" and the "odor of burning flesh was present."Adams told police the victim was "beating" her, so she stabbed him with a knife in self defense, according to court documents.A bloody pocket knife and a broken cell phone matching the victim's cell phone were found in the kitchen, court documents said.Police said investigators have a "good idea" of who the victim is, but more definitive information is needed and next of kin needs to be notified."
