Law enforcement personnel exit a helicopter after it dropped them off next to the Arboretum Oaks apartment complex, the scene of a deadly shooting in Austin, Texas, April 18, 2021.

A former Texas deputy wanted in the deaths of three people was arrested Monday after a 20-hour manhunt.

Stephen Nicholas Broderick, 41, was arrested early Monday after deputies tracked him down following two 911 calls about a man walking down a road in an Austin suburb about 32 kilometers from the scene of the weekend attack.

Broderick, who had a pistol in his waistband, was taken into custody without any further complications.

"I'm truly heartbroken that a former Travis County Sheriff's Office Deputy is the suspect in such a horrific incident," Sheriff Sally Hernandez said in a statement.

The shooting happened around noon Sunday at an apartment complex near a popular shopping area called the Arboretum.

Authorities described the shooting as a "domestic situation," and Interim Austin Police Chief Joseph Chacon said that Broderick knew and targeted the victims — two females and a male who were pronounced dead at the scene.

Broderick investigated property crimes with the office until he was arrested in June and charged with sexually assaulting a child, according to Kristen Dark, a spokeswoman for the sheriff's office. Broderick was placed on administrative leave and resigned later.

Prosecutors have said they would pursue capital murder charges against Broderick, who is being held at the Travis County Jail without bail.
