Missing CDC researcher found dead in river

A body pulled from the Chattahoochee River in Atlanta has been identified as Timothy Cunningham, a researcher from the Centers for Disease Control and Prevention who mysteriously disappeared in February, Atlanta police confirmed Thursday.

Police and the medical examiner identified drowning as the preliminary cause of death during a press conference Thursday. Though they reported that they did not see any evidence of foul play, they added they were waiting for additional evaluations to make a final determination, including whether the death might have been a suicide or homicide.
