The woman who opened fire at Joel Osteen’s Houston-area mega-church on Sunday has been named as Genessee Ivonne Moreno, 36, according to the Houston Chronicle, as authorities revealed she had ‘Free Palestine’ written on her weapon.

Moreno entered Osteen’s Lakewood Church just before 2 p.m. with a boy, believed to be about 4 or 5 years old, and opened fire into the church.

Two off-duty officers working security at the church — a Houston cop and an agent with the Texas Alcoholic Beverage Commission — returned fire and fatally shot the woman, Houston Police Chief Troy Finner said Sunday.

The boy was also shot and has been hospitalized in critical condition. It’s unclear who shot the boy and what his relationship was with Moreno.

One 57-year-old civilian bystander was also shot in the leg, according to ABC News.

While law enforcement told ABC about Moreno’s gun’s being daubed with “Free Palestine” a motive in the shooting remains unclear, and police are still investigating.
