Are you talking about the 10-80 on the silver Toyota? It was started in Tooele county by a Fish Cop, 1A40, who was in an unmarked with lights and sirens. Guy would not pull over, he called Tooele Dispatch, 40000, and asked for assistance but no units were in position. As the chase continued over in to Utah county Tooele Dispatch asked 1A40 if he had Utah Regional and switched him to that, by that time they were getting on to I-15. UHP units finally got involved about the 263 mile marker southbound and the driver still did not pull over. They were preparing to spike him when he pulled off at Spanish Fork exit.
Was a low speed chase with speeds never exceeding 80mph and at time were as low as 43mph. They went 10-60 @1143hrs and Utah County dispatcher sent all traffic back to their normal channels. There was mention of a medical issue then things got quite.
