Manor Police Department released this footage on Monday, showing the man being taken into custody.
The Austin Police Department said the suspect, Stephen Nicholas Broderick, was the ex-husband of one of the victims. The 41-year-old is reported to be a former detective with the Travis County Sheriff’s Office who resigned after he was arrested last year on child sex assault charges.
Police responded to reports of a shooter at Great Hills Trail and Rain Creek Parkway in northwest Austin on Sunday. The three victims were pronounced dead at the scene.
Broderick faces charges for capital murder, police said. Credit: Manor Police Department via Storyful
