ROCHESTER, Minn. – Police clocked Noah Doherty, 22, at 144 mph on his motorcyclke north of Rochester on Highway 63. When a cop caught up at stop sign, Doherty slammed the squad car door on the office’s elbow. Yes, it hurt, the officer said. But he unholstered his Taser and subdued Doherty. A passerby helped cuff Dougherty. Why didn’t you stop earlier in the chase? “Didn’t hear the siren. Had earbuds.” Why so fast? “The excessive heat.”  Dougherty, of Pine Island, cooled off in jail.
