A domestic dispute in the Austin’s Colony area turned fatal on the morning of March 3, 2026. Deputies responding to a 911 call just before 11:30 a.m. found 63-year-old Cynthia Rios Juarez of Round Rock with a severe gunshot wound at a home in the 4500 block of Secure Lane. Life-saving efforts including CPR were attempted, but she was pronounced dead at 12:01 p.m.

Also at the scene was her 49-year-old brother, Courtney Leander Nation of Austin, who had non-life-threatening gunshot wounds and was taken to a local hospital. Investigators believe Nation shot his sister during a family dispute and was then shot by another brother who was present. Nation has been charged with Cynthia’s murder; the brother who shot Nation is not currently facing charges as detectives continue to investigate motive and the sequence of events.
