DJ STEPHEN ‘TWITCH’ BOSS ELLEN’S DJ DEAD AT 40

Stephen “tWitch” Boss, the famed DJ on Ellen Degeneres’ talk show, is dead … and TMZ has learned it appears to be a suicide.

Law enforcement sources tell us Stephen’s wife Allison Holker ran into an LAPD station Tuesday, and she was frantic because she said Stephen had left home without his car — something that was not like him at all.

We’re told, a short time later police got a call for a shooting at an L.A. hotel … and they found Stephen there, dead from an apparent self-inflicted gunshot wound.

Holker tells People, “Stephen lit up every room he stepped into. He valued family, friends and community above all else and leading with love and light was everything to him. He was the backbone of our family, the best husband and father, and an inspiration to his fans.”

She continues, “Stephen, we love you, we miss you, and I will always save the last dance for you.”
