Edward Furlong -- Released from Jail ... Looking Like Death

Edward Furlong was released from an L.A. jail last night following his domestic violence arrest -- and he looked like a harbinger of death on his way out, wearing a Halloween-appropriate skull t-shirt.

The troubled "Terminator 2" star was released around 6:30 PM on $50,000 bail.

TMZ broke the story, Furlong was busted early yesterday morning at LAX for allegedly getting physical with his girlfriend during an argument.

Law enforcement sources tell us, police observed marks on Furlong's GF's arm ... and that's why they placed him under arrest.
