On the evening of September 15, 2024, 41-year-old Teressa Calligan was shot and killed while stopped at a traffic light on Airline Highway in Baton Rouge, Louisiana. A respected community educator, cybersecurity specialist, and minister, she had just left a campaign event for a relative running for a local judgeship. Someone in a vehicle that pulled alongside her SUV opened fire, striking her multiple times; her vehicle then rolled into the intersection and struck several other cars, including a sheriff’s office cruiser. Two deputies in the cruiser were hospitalized with non-life-threatening injuries; Calligan was pronounced dead at the scene.

Calligan, a mother of two and the Dean of Coding at the Walls Project, was remembered for mentoring teens and her devotion to helping others. Family members said they were bewildered and suggested she may have been mistaken for someone else. In June 2025 authorities arrested three men they identified as local gang members: David Catherine, Roger Parker, and Robert Lewis. All three were later indicted on first-degree murder and obstruction of justice charges. Catherine pleaded not guilty and filed a notice of alibi; at a bond hearing a witness said he had been with her that night, but a judge denied bond and the case remained pending a jury trial as of August 2026.

Does anyone in Baton Rouge have information about Teressa Calligan, her movements that night, or the people involved?
