A spokesman for the Cheyenne Police Department says tickets are still available for the "Why Teens Kill" seminar May 21 at the Cheyenne Civic Center.

Officer Dan Long says the event will feature Phil Chalmers, who Long says is the nation's leading authority on juvenile homicide and juvenile  mass murder. Chalmers has interviewed over 200 teen killers and school shooters and has been studying the subject for over 25 years. Chalmers will be joined in Cheyenne by Joe Schillaci from the A&E television network series "The First 48".

The seminar is scheduled for 8am until 4pm on May 21 at the Cheyenne Civic Center. Tickets are available by calling the Civic Center Box office at (307) 637-6363.
