Authorities say 17-year-old Jason Montes was found lying face down with a gunshot wound to the back.
Deputies say Montes was partially-clothed and his body looked like it hadn't been there long.
On Thursday, teens were walking home from George Bush High School when they found Montes' body near a retention pond in the Great Oaks neighborhood.
Investigators are working to find out how and why the teen was killed.
