At 58:50 in the entire gang is getting into the van trying to get away from a pimp that they owe money to. The person your looking for is Linus, the first person you see getting into the back of the van. He is clearly seen sitting behind the driver Hutch at 58:54. At 59:00 it is clearly shown that the van side door is completely closed meaning it would have to be opened from the inside since the pimp is on the hood of the car and can't reach the handle. 10 sec. later it shows Linus nowhere to be found in the van. 15 sec. after that it shows an empty seat and the van side door is completely open and Linus is laying on the ground supposedly where the van took the hard turn left.
