Friends and family said their final goodbyes Saturday at the funeral for District Attorney Ken Thompson.

Mayor Bill de Blasio, Governor Andrew Cuomo and U.S. Attorney General Loretta Lynch attended the service at the Christian Cultural Center in East New York.

Thompson died Sunday at the age of 50, days after announcing he had cancer and would be taking time off for treatment. Mourners say Thompson, Brooklyn's first African-American DA, was a champion of justice.

"He was never looking for the limelight or anything," said Graham Weatherspoon, retired NYPD officer and board member on the Amadou Diallo Foundation. "He just wanted to do what he could do to help people. Whether it was as a defense attorney or prosecutor, he just wanted to help people he was adjoined with. And this is what public service is."

During his time as DA, Thompson focused on exonerating the wrongfully convicted, and refrained from prosecuting people for low-level offenses such as possession of small amounts of marijuana.
