A Holiday man with an outstanding DUI manslaughter warrant turned himself in during a traffic stop Wednesday.
Largo police say they pulled over Brian Winthrop about 8:30 a.m. after clocking his motorcycle traveling 48 mph in a 30 mph zone near 5100 150th Ave. in Clearwater.
He was not wearing a helmet, and police said they discovered he did not have a motorcycle endorsement on his license.
During the stop, Winthrop informed the officer of the warrant stemming from a fatal crash that happened about 3:30 a.m. Nov. 15.
According to court papers, Winthrop, 33, was traveling north on U.S. 19 at Bryan Dairy Road in Pinellas Park when he struck motorcyclist Michael Burton with his blue Dodge Intrepid.
Winthrop, who authorities said smelled mildly of alcohol and had bloodshot, watery eyes, told officers the motorcycle swerved into him as he changed from the median lane to the middle lane.
Authorities said he told them he'd had one beer roughly four hours earlier at a party.
However, blood drawn about 90 minutes after the crash revealed an alcohol level of 0.112; about three hours after the crash the level was 0.092.
The level at which a driver is considered impaired is 0.08.
Officers determined Winthrop had failed to yield while changing lanes and rear-ended Burton's motorcycle.
Burton was pronounced dead at the scene.
Jail records show Winthrop was released Wednesday afternoon on $50,000 bail.
