The personnel file of a South Carolina police officer who shot and killed a teen during an attempted drug bust shows no disciplinary problems.

The city released Lt. Mark Tiller's file Monday to media outlets. The documents show one performance review from June 29 in which the officer received ratings of "excellent" in five of six categories and was rated "good" in job knowledge. Tiller was hired by Seneca in 2010.

Tiller says he shot 19-year-old Zachary Hammond during the bust last month because the teen drove his car at him.

Hammond's family says autopsy results show Hammond was shot through the driver's side window from behind, indicating there was no danger to the officer.

Both the officer and the teen are white.
