Colleagues and family members joined together Friday to say goodbye to a Mount Vernon officer who committed suicide this week.

More than 500 relatives, friends and fellow police officers from every department in Westchester County filed into St. Elizabeth Ann Seton Church in Shrub Oak to pay their respects to 23-year-old Daniel Vize.

The mourners stood in silence before Vize?s coffin, with only the sound of a bell tolling mingled with quiet sobs filling the air.

"He always had a good word for anybody, he was a wonderful human being," says Vize's friend, Dr. Gary Simon.

The young officer was found dead inside his car on the top floor of a parking garage near the Mount Vernon police station after he failed to report for work on Labor Day. Detectives say he used his own service weapon to shoot himself.

The Mount Vernon police commissioner and Vize?s colleagues are heartbroken over his death.

?We certainly don't know what led to this tragedy, we have to stand by this family and be as supportive as we possibly can be,? says Mayor Clinton Young.

Vize comes from a family of police officers. His father, John Vize, is a New Castle police lieutenant. At the funeral, he was clutching his son's hat in a state of disbelief before giving a final farewell salute together with his fellow officers.

Following the service, Vize?s body was buried at Rose Hill Cemetery in Putnam Valley.
