Some stories from Seagoville’s past are hard to revisit, but they are part of our shared history, and they deserve to be remembered with care and respect. This Seagoville Flashback looks back at one of the most painful moments in recent community memory: the murder of Brii Jackson, a Seagoville High School freshman, in October 2017.
According to a report from FOX 7 Austin published on October 11, 2017, Brii was a 15 year old Seagoville High School freshman who was shot and killed in far southeast Dallas County. The Dallas County Sheriff’s Office arrested a 14 year old boy in connection with her death.
The loss hit especially hard because of its timing. Brii had celebrated her fifteenth birthday with family just the day before she was killed. Relatives told FOX 7 Austin that they had a great time celebrating that Friday, and less than 24 hours later, Brii was dying just feet from her front door.
Family members said the boy arrested in her death lived in the same mobile home park and that the two had known each other for years. According to FOX 7 Austin, Brii’s aunt, Tracie Addington, said, “They were friends at one point. They’ve known each other for 6 or 7 years. It’s heartbreaking, and I do not wish this on any other family.”
The outlet reported that the Dallas County Sheriff’s Office did not release the suspect’s identity because he was a juvenile, and it was unclear at the time where he obtained the firearm.
Family members told FOX 7 Austin that Brii had been walking with her 14 year old sister and a 10 year old cousin at the time of the shooting. Her sister held her as she lay bleeding in the street while they waited for help to arrive.
Those who knew Brii described her as smart and popular, a teenager with a bright future ahead of her. In the days after her death, classmates at Seagoville High School grieved together, and the community was left trying to make sense of how one child could take the life of another.
We were not able to locate publicly available information confirming the final legal outcome of this case, which is common in matters involving juvenile defendants, since those proceedings are often sealed under Texas law.

Nearly a decade later, Brii Jackson’s name still belongs to Seagoville. Moments like this remind us why community, connection, and looking out for one another’s children matter so much here at home.
