Teachers witness some of the hardships students face everyday.
It's those hardships, Sgt. Josh May says that can lead some kids down the path of joining a gang.
As the head of the police department's Organized Crime Unit, May works with gangs in Chattanooga on a daily basis.
In fact, he spent the early morning hours on the scene of the city's latest homicide where a gang members was killed before Wednesday's presentation.
He used his knowledge and background to help teachers at Brown Middle School understand what may lead to a child joining a gang and the signs to look out for.
It's all in hopes of helping teachers identify the signs that a child could be headed in that direction, figure out what they may be lacking in their life and help steer them away.
Many were surprised to learn that those affiliated with gangs don't just stay in the inner city.
"With the explosion of social media and just the way the world has become more fluid on the internet, there's opportunities for individuals across the county, across the state. No matter what school or what neighborhood you grow up in to be involved in this type of activity," May said.
May hopes presentations like these help those in the community learn more about gangs and how they operate.
Many teachers were interested in the role girls play in gangs and some of the colors, signs and symbols affiliated with gangs in town.
It's important to note, anything affiliated with gangs are not allowed inside schools.
