A single witness, a BU affiliate saw Daverio leaving his office March 16, said BU Police Captain Robert E. Molloy.

Surveillance camera records shows him leaving the building with a white plastic bag.

After leaving his office, police officials said Daverio walked east toward the BU Bridge. Daverio’s wallet was found in his office, Molloy said.

His body was found near the DeWolfe BU Boathouse on Memorial Drive by a local crew team at around 7:30 p.m. Monday.

Molloy said that Daverio was wearing the same clothes when found that he had had on when last seen.

Colleagues doubt the possibility that Daverio committed suicide.

Schumann, the composer Daverio studied and wrote about extensively, attempted to kill himself by throwing himself in the Rhine in 1854. He died two years later.

Molloy told the Associated Press that investigators were aware of the coincidence, but didn’t think it played a role in Daverio’s death.
