A man was shot to death at a Midtown MARTA station Sunday night, officials said.

A MARTA security officer heard gunshots around 9 p.m. at the Arts Center station, less than a mile west of Piedmont Park. The guard found Demarco Mathis, 45, with a gunshot wound on the bus loop, according to MARTA officials.

Mathis later died at the hospital.

MARTA’s security officers ride buses and trains to assist people and alert officers to dangerous situations. They work alongside MARTA police, but they are not sworn officers.

Police have not released any additional details about the case. They did not provide a suspect description but said they are working to identify the shooter.

This shooting is not the first to happen on MARTA property this year. According to agency data, there were five homicides on MARTA property in 2023 and 11 since 2018. However, it is unclear where on MARTA property these incidents took place or by what means the deaths occurred.

The Atlanta Journal-Constitution previously reported that two shootings occurred days apart in May, leaving one person dead and another injured.

Jah-Malik Marcano, 23, was shot and killed while riding an eastbound train May 9, authorities said. Five days later, one person was arrested after allegedly shooting another at MARTA’s East Point station, officials said.

Just a few months earlier, two serious stabbing incidents occurred weeks apart at the Five Points station. A non-fatal shooting also took place there in March.
