Reviews

I was fortunate to work with Detective Gary Sweet at the Garland Police Department when I was a Forensic Investigator.
If we had a major case, we always wanted Det. Sweet to be primary because we knew he was going to do such a great job. Sweet has the ability to make everyone involved in a case feel important and their input valued. I witnessed Det. Sweet get confessions from individuals that wouldn’t talk to anyone else. One of the most amazing things about Det. Sweet is that he was able to get 2 murder convictions on cold cases where the evidence had been destroyed.
If you are able to attend any of Det. Sweet’s classes there is no doubt that it will benefit your career.

I have had the privilege of personally working with Detective Gary Sweet while I worked in the Garland Police Department Forensic Investigations Unit.
I was recently able to attend a forensic symposium where he presented a cold case that he worked. Sweet presented the case in such a way that he was able to capture my attention from the beginning until the very end. I learned how he became involved in the homicide cases and how he was able to link the suspect to the cases.
Sweet is a wealth of knowledge. I highly recommend anyone in law enforcement to attend his training classes. Any helpful tips that you can learn from Sweet will benefit you and your agency
