ARLINGTON (CBSDFW.COM)A 16-year-old boy gunned down near a North Texas high school on February 6 has been identified.

Investigators quickly identified a suspect and four hours after the shooting announced they had the boy in custody. Police did not release a lot of information about the alleged shooter because he is underage.

Arlington Police Chief Will Johnson expressed his frustration about the crime on social media, saying, “This senseless act of gun violence has no place in society and our hometown community.”

Johnson said as the department gathers more information about the young suspect they will pay particular attention to how the boy got his hands on the “firearm used in the offense.”

Police say the suspect and the victim knew each other.

Grief counselors are at Arlington High this morning to offer assistance to students, teachers and staff. Administrators with the Arlington Independent School District say they will remain on the campus as long as needed.

Before classes began Friday JROTC students at the school made the decision to fly the school flag at half staff in memory of Reynolds. Students told CBS 11 News the teenager was a sophomore.

“I’m really sad about him,” said Reynolds friend, Christian Vasquez. “When I found out about it I was gonna cry. Because I… he was one of my favorite friends actually.”
