A woman who fired a rifle inside a Houston megachurch Sunday and was killed by law enforcement had a history of mental illness, a string of arrests spanning nearly two decades and family who had previously sought help from authorities to prevent her from accessing weapons, according to interviews and court documents.
Investigators are still trying to decipher what motivated a 36-year-old mother to open fire with a semi-automatic rifle in a popular Houston megachurch Sunday in an incident that left two people injured, including her 7-year-old son, before she was killed by law enforcement.
