The body of a teenager was found Wednesday afternoon behind Allenbrook Elementary School in northwest Charlotte, and CMPD has launched a homicide investigation.

Authorities identified the teen as 18-year-old Tyshaud Nikese Brown. His body was found lying near a baseball field behind Allenbrook Elementary, in the 1400 block of Allenbrook Drive. Police believe he had been shot.

Detectives said they do not believe the incident was related to any of the students or staff at the school, which has more than 500 students in grade K-5. As detectives were still at the scene investigating the case, parents picking up their children were asked to go to the front door of the school.

According to a police report, Brown was reported missing at 6:26 a.m. Wednesday morning. Officers search the area but didn’t find him, according to the report.

Brown’s mother told WBTV that her son left home Tuesday evening and didn’t return. She reported him missing the next morning.
