Des Moines police say they’ve arrested a suspect in a fatal hit-and-run in the capital city. The weather’s been mild and dry, and Lieutenant Todd Dykstra says on Friday night a woman who’d been visiting friends set out for home riding a bicycle. Forty-six-year-old Tina Brown and her bicycle were struck and she died.

But all they had was a suspicion that the vehicle was maroon in color…no eyewitness, no other clues. Late Sunday night police got a tip about the person who might have been involved in the hit-and-run, and acting on that information they worked all night, went and found the car, a maroon Chevy Monte Carlo with front-end and window damage.

The traffic investigators tracked it down and figured out that 36-year-old John Quincy Adams was the driver of the car at the time of the fatal crash. On Tuesday afternoon Adams turned himself in. He’s now charged with homicide by vehicle while intoxicated, and failure to render aid.
