Original (12:24 p.m. Sunday): Three adults are dead and an armed suspect is still at large in Northwest Austin following a shooting, according to Austin police.

The incident began at 11:42 a.m., Sunday, in the 9600 block of Great Hills Trail and Rain Creek Parkway, in the Arboretum area.

Officers were first notified with a report of a shooting or stabbing in the area, which is the department’s highest priority call, according to police. The first officer arrived on scene at 11:46 a.m.

Moments later, a “reverse 911 activation” was sent out for all residents in the area to know that a shooting happened and that they all needed to shelter in place, according to police.

Three adults -- two women and one man -- were found injured at the scene with gunshot wounds, police said. They were later pronounced dead on scene, according to officials.

The suspect and the victims did know one another, and the shooting is deemed as a domestic incident, police added.

A child was also involved in the incident but details are limited at this time. Officials said the child is now in police custody.

The suspect was identified as Stephen Nicholas Broderick, 41. He’s still at large, is considered armed and dangerous and is described as 5,’7″ with an average build, police said.

Broderick, at one-time, was a deputy for the Travis County Sheriff’s Office, according to police.

Broderick was last seen wearing a gray hoodie, sunglasses and a baseball cap. His whereabouts are still unknown and he is considered armed and dangerous.

Authorities said they are concerned that Broderick could take a hostage, shelter somewhere and wait for police to leave. That’s why residents in the area were asked to shelter in place and to call 911 if they have any more information on his whereabouts.

As of Sunday evening, officials lifted the shelter in place order for area businesses and residents, though they are asked to still remain vigilant.

Those assisting in the search efforts include Austin police, air support, K9 teams, several SWAT teams, 75 FBI agents, the US Marshals and officers from other police departments. The search efforts will continue until Broderick is located.

Any 911 calls for medical response in the area will be handled by Austin-Travis County EMS Medics in an “alternate response model” other than an ambulance, due to the active situation, officials said. Delays may also occur.

This is a developing story and we’ll bring more details as they become available.
