Authorities said a preliminary exam of the body of Boston College student Franco Garcia shows his death is consistent with an accidental fall into water.
Suffolk County District Attorney Daniel Conley's office said Thursday that the exam showed Garcia didn't suffer broken bones or other significant injury.
Authorities haven't ruled out foul play and will be doing further toxicology tests as part of the autopsy.
Garcia disappeared Feb. 22 after a night of drinking with friends at a bar near campus.
Authorities did several searches of the Chestnut Hill Reservoir before Garcia's body surfaced there Wednesday.
They said they found cash among personal effects on his body.
His family previously said that the student's wallet was found in his pocket, and that police also recovered his eyeglasses.
The 21-year-old was a junior chemistry major who worked full-time as a pharmacy technician and lived with his family.
Garcia played clarinet in Boston College's Symphonic Band, and also sat on the band's executive board.
