A teenager was shot and killed late Tuesday at a gas station in Berkeley, Mo., according to St. Louis Post-Dispatch. According to Addicting Info, the victim was another black teen gunned down by police.

The police have issued this statement, according to the Post-Dispatch:

"The St. Louis County Police Department is conducting an investigation into a shooting death involving a Berkeley, Missouri police officer.

"At approximately 11:15 p.m. on Dec. 23, 2014, a police officer with the City of Berkeley was conducting a routine business check at the Mobile Gas Station located at 6800 N. Hanley when he observed two male subjects on the side of the building.

"The Berkeley Police Officer exited his vehicle and approached the subjects when one of the men pulled a handgun and pointed it at the officer. Fearing for his life, the Berkeley Officer fired several shots, striking the subject, fatally wounding him. The second subject fled the scene.

"The Berkeley Police Department requested the St. Louis County Police Department's Crimes Against Persons Unit to handle the investigation. St. Louis County Police Detectives have recovered the deceased subject's handgun at the scene.

"At this time, we cannot confirm the identity of the deceased subject. The investigation is on-going and further details will be provided as the investigation proceeds."

The victim was identified as 18-year-old Antonio Martin, by Toni Martin, the victim's mother. Her son's body remained on the ground until 1 a.m., flanked by police cars, according to the Post-Dispatch. According to the victim's mother, Antonio was hanging out with his girlfriend. The girlfriend has not made a comment to reporters yet.

A crowd of 60 have gathered at the scene, including ministers and protesters active since the fatal shooting of black teen Michael Brown by a white police officer in August.

The shooting occurred at a Mobil gas station on North Hanley Road in Berkeley, southeast of the intersection of Interstates 170 and 270, two miles from Ferguson, Mo.

According to the Post-Dispatch, protesters "grew rowdy." Explosive flashes were set off, but it is unclear by whom. Vandals also damaged a QuikTrip store near the Mobil station before police had a chance to close access to the store.
