Elden Campbell, a 15-year NBA veteran who played for the 2004 world champion Pistons team, died Monday at the age of 57.

The person who phoned cops to report Elden Campbell’s death told police the former Lakers center’s body appeared to have washed ashore “in a white casket” in Pompano Beach, Fla.

Campbell’s sister, Sandra, told The Post on Wednesday her brother had been out fishing just prior to his passing.
