A 23-year-old Victoria man is jailed Friday over the March slaying of a Child Protective Services administrator.
The Houston Chronicle reports the suspect is the son of the victim's former boyfriend.
The strangling of 53-year-old Sally Blackwell had sparked concern for the safety of CPS workers around the state.
But the Victoria Advocate reports officials believe Blackwell's death was not job-related.
Jeffrey Frank Grimsinger is held without bond in the Victoria County jail on a capital murder charge.
The Chronicle reports Grimsinger is the son of Blackwell's former boyfriend, 57-year-old Michael Grimsinger.
The older man told the newspaper, quote: "It's my son. I don't get it. I just don't get it."
Sheriff Michael O'Connor says DNA evidence linked the younger Grimsinger to the crime. Further details weren't immediately released.
Jeffrey Grimsinger has misdemeanor convictions for marijuana possession and resisting arrest from unrelated incidents in 2001.
