Cynthia Lightsey, 63, of Houston, Texas, was killed on April 17, 2015. Police say her son, 37-year-old Joseph Lightsey, walked into a medical center and confessed to shooting his mother; he was arrested and held on a murder charge with bail set at $100,000. Court listings at the time did not show an attorney for Joseph Lightsey.

The case centers on a familial killing whose key detail is the suspect’s on-the-record confession at a medical facility.

Did anyone know Cynthia or Joseph Lightsey, or have information about what led up to April 17, 2015?
