The Harris County Institute of Forensic Sciences determined Thy Mitchell, along with children Maxwell and Maya, died by homicide. All three had a gunshot wound to the head.
Authorities have not detailed the circumstances surrounding the deaths. Houston police reported finding the family of four inside their River Oaks-area home Monday evening, describing the incident as a possible murder-suicide.
The case has also renewed conversations online around domestic violence, mental health and the ripple effects these tragedies leave behind for families and communities.
This is a developing story.
