A Miami University student has died, three weeks after falling from his loft-style bed.

The Montgomery County coroner's office says 20-year-old Aaron Miller of Bellbrook died this weekend from injuries he received when he tumbled nearly six feet from his elevated bed in the Pi Kappa Phi fraternity house at the school in Oxford.

Investigators still aren't sure how Miller fell.

He had been hospitalized since the accident and died Saturday at Hospice of Dayton.
