On a quiet Sunday morning, a 47-year-old tree trimmer with six drunken driving convictions headed out on a circuit of his favorite bars in the West Denver suburbs – downing a beer and three shots of peppermint schnapps at his first stop, a beer and a shot of tequila at his second, and two beers and five whiskeys at his third.Then Todd Grudznske climbed behind the wheel of his 6,000-pound pickup, roared down a city street at 60 mph, and killed a young woman named Angela Wimmer, who was sitting at a red light.
