2:10 p.m. UPDATE: in Malibu has been identified as Joshua A. Feinberg, 21, of Agoura Hills.
The cause of death is expected to be revealed on Thursday after further examination, said Craig Harvey, spokesman for the Los Angeles County Department of Coroner.
A 21-year-old college student whose body was found Tuesday at the bottom of the Rindge Dam in Malibu apparently committed suicide, Sgt. Vivian May of the Malibu/Lost Hills Sheriff's Station told Malibu Patch on Wednesday.
The circumstances surrounding the death were under investigation, May said. She said the student, whose name has not been released, apparently jumped to his death.
"There was a text message to a friend and a note left in his car," May said. "He was upset about his grades."
The recipient of the text, whose name also was not released, went looking for his friend, May said. He got lost, and was later found uninjured on a ledge by the Malibu/Lost Hills search and rescue team, May said.
Malibu Patch will have more information on this story when it becomes available.
