Skateboarding star Terry Kennedy has just been charged with first degree murder ... TMZ Sports has learned.
A spokesperson for the DuPage County State's Attorney's Office tells us the charge was formally filed Monday afternoon ... after the man Kennedy allegedly attacked at an Illinois motel last week died over the weekend.
We're told Kennedy appeared in court for a bond hearing after the filing ... though the proceedings were continued until Tuesday morning.
Kennedy is now facing up to life behind bars if convicted.
