The Virginia medical examiner's office says it is withholding the cause of death for a University of Virginia student.

The agency said Tuesday that the Charlottesville Police Department requested that 18-year-old Hannah Graham's cause or manner of death not be released yet.

Her remains were found Oct. 18 near Charlottesville. Graham disappeared Sept. 13 after a night out with friends.

Charlottesville and Albemarle County police referred questions to the county prosecutor's office, which declined to comment.

The man Graham was last seen with, 32-year-old Jesse Leroy Matthew Jr., is charged with abduction with intent to defile Graham. Authorities said DNA evidence linked Matthew to a 2005 sexual assault case in Fairfax. DNA evidence in the Fairfax case has been linked to the 2009 disappearance and death of Virginia Tech student Morgan Harrington.
