Police arrest man accused of woman’s shooting death in Baton Rouge

BATON ROUGE, La. (Louisiana First) — A Baton Rouge man was arrested in connection with a deadly shooting in 2024.

According to the Baton Rouge Police Department, David Catherine, 22, was arrested after police believed he was involved in the shooting death of Teressa Calligan, 41.

The shooting occurred at the intersection of Airline Highway and Greenwell Street on Sept. 15, 2024. Calligan was found in a vehicle with multiple gunshot wounds. Investigators learned that a vehicle pulled alongside her and opened fire. Police said after she was struck, her vehicle hit other vehicles, including a deputy’s unit.

Catherine was arrested and booked in the East Baton Rouge Parish Prison on charges of first-degree murder.

BRPD said on investigation is ongoing.

Attorney General Liz Murrill released a statement on Catherine’s arrest.

“Remember when I asked who thought it was a good idea to give him free run at one of our middle schools? Glad that the family of Teressa Calligan finally has some closure. Please continue to keep them in your prayers,” said Murrill.

In March 2025, Catherine, who is alleged to have gang ties, visited a local Baton Rouge middle school.

Murrill criticized the school system after allowing Catherine on school grounds and raising concerns about school safety and privacy violations.

She made posts on social media, stating the behavior is ” absolutely unacceptable,” and the parish allowed a “person with a known gang affiliation to make a video with kids using offensive, racist language and glorifying violence, and basically turns a day at elementary school into a day of recruiting for a gang.”
