Social media users posted photos and videos of the victim’s emotional mother bursting into tears the moment she learns her son is dead.

“They started shooting,” Toni Martin, the teen’s mother told reporters.

She added that her son was with his girlfriend at the time of the incident. The girlfriend remains at the scene, but won’t speak to reporters.

"That’s my baby,” Toni Martin was crying over and over again.

Photos reportedly showing Antonio’s girlfriend with him at the time of the shooting were released by the St. Louis Post-Dispatch.



Martin attended Jennings Senior High School in St. Louis, Missouri, according to Twitter users.

Antonio’s mother later told the St. Louis Post-Dispatch that her son was expelled from school, but was trying to gain employment via Jobs Corps, a US program offering free-of-charge education and vocational training to young people.

Dozens of Twitter users claim Martin was unarmed when he was shot. People gathered at the scene, demanding police explain what happened.

They are shouting “Innocent people!” and “What is that?”

“You drop four bodies, I'm giving you four seasons of protest," a woman was heard shouting at a police officer.

Some angry witnesses have managed to break through police tape and are now at the scene.

Twitter users report the body of Antonio has been blocked from view. According to bystanders, the teen was alive for about 30 minutes after being shot.

The incident occurred as US police are being widely criticized for their brutal tactics against suspects, especially African Americans. Over the past weeks tens of thousands of Americans across the country have taken part in massive marches protesting the slaying of unarmed black men by police.
