A troubled Davenport teenager was arrested for speeding Thursday, on the first day of class, but he wasn’t headed for school. Police say 17-year-old Jeremy Canady sped through a 25 mph school zone at 60. Police say they had already clocked him going 35 in a school zone and he was trying to flee. Police Captain David Struckman says Canady is a student himself at an alternative school. But he skipped the first day of classes. Now he’s being held at a juvenile detention facility. Police say Canady was just released from an 8-month stay in the State Training School in Eldora. They say he has scores of license revocations and suspensions and 46 traffic convictions during 2001 alone.
