Officials on Monday released the results of Thibault deSaintPhalle's autopsy. The Washtenaw County Medical Examiner determined the cause of death to be "heroin and cocaine abuse" and the manner of death "accidental," according to a release from U-M police.

Housing Security officers keyed into the student’s room shortly after midnight Nov. 18 and found the deSaintPhalle deceased in his bed. A well-being check had been requested for the student who had reportedly not been seen over the weekend.

DeSaintPhalle, from California, was a student in the School of Music, Theatre and Dance.
