Autopsy unable to determine Jenkins' cause of death

MINNEAPOLIS (AP) -- University of Minnesota senior Chris Jenkins apparently drowned but his cause of death was ruled unknown, the Hennepin County medical examiner's office said Monday.

Jenkins, 21, was last seen alive Halloween night leaving a downtown Minneapolis bar. His body was recovered nearly four months later south of the Horseshoe Dam in the Mississippi River.

An autopsy found Jenkins' manner of death was undetermined, the medical examiner ruled.

Jenkins, who grew up in Eden Prairie, attended the university's Carlson School of Management and was scheduled to graduate this spring. His sister will accept a posthumous degree in his honor Sunday.
