Unarmed 19-year-old man fatally shot by police

(CBS/AP) AMES, Iowa -  A 19-year-old man was fatally shot by police on the campus of Iowa State University after his father called authorities to report that the teen had stolen his truck, reports CBS affiliate KCCI. Tyler Comstock, 19, of Boone, was shot dead by Officer Adam McPherson, an 8-year-veteran of the department, at the end of an at-times high-speed pursuit through the city's streets that ended on the college campus, reports the station.
The officer who shot the teen in Ames, Iowa Monday was cleared Thursday of wrongdoing, and the investigation was closed, reports the DeMoines Register.
A state's attorney says the police officer who fatally shot the apparently unarmed man "acted reasonably under very difficult circumstances and....use of deadly force was justified,"  reported KCCI.
Tyler Comstock's father, James Comstock, told the Des Moines Register he refused to buy his son a package of cigarettes, which angered him and started the incident. James Comstock had called police to report the stolen vehicle.

Comstock told the newspaper he's outraged police shot his son. Other family members told the newspaper police should have backed off the pursuit because they knew who they were chasing.
