A jazz musician found stuffed inside a trunk in his Brooklyn basement had been stabbed to death, the Medical Examiner’s Office said yesterday.

Stanley Wright, 62, had multiple knife wounds to his neck and torso.

His body was found early Tuesday after his son Khalil, 36, went to the Brownsville home, found the door open and called cops.

Wright — a widower who had performed at Lincoln Center — was last seen Friday moving his car, relatives said.

He was beloved by many in his neighborhood, where he taught piano lessons to local kids. Wright was the father of three, including “Blade” actress N’Bushe Wright.
