She said she feared he was going to murder their entire family - months before he shot dead their daughter, her boyfriend and one another while on bail for rape.

The wife of a killer Austin police who killed his daughter, daughter's boyfriend and another woman on Sunday begged a judge not to let him be free last year, saying she thought he was going to hurt their family.

Stephen Broderick was arrested on Monday walking along U.S. 290 after two people phoned police. He was taken into custody without incident but had a pistol in his waistband.

On Sunday, Broderick shot dead Alyssa and Alyssa's boyfriend, Willie Simmons, then went on the run.

A third woman was also killed. She has been identified as his estranged wife Amanda by friends on social media and one reporter, citing Austin Police sources.

Austin Police Department would not confirm the victims' identifies on Monday morning when contacted by DailyMail.com.

Alyssa and Willie were both named by their school district. Another child, believed to be Broderick's son, was not harmed. Amanda was named by a friend on social media.

Broderick was a cop until June 2020, when he was arrested on suspicion of sexually assaulting a 16-year-old girl. The Statesman reports that the victim was a family member.

He was released from custody after posting a $50,000 bond and was told not to go within 200ft of his daughter, Alyssa. In November, a judge agreed to remove his ankle monitor after his lawyer pleaded that he'd proved he could be trusted not to wear it.

His wife Amanda had pleaded with the judge not to, saying she feared for her life.

'I'm afraid he will try to hurt me or my children, because these allegations have come out and he may lose his career.

'Stephen has prior military experience and is SWAT trained. If he wanted to hurt someone, he would know how,' she said.

State District Judge Karen Sage agreed to remove the monitor despite Amanda's pleas.

She told The Statesman on Sunday that it was a 'pretty common thing to do'.

'He had been on GPS for (five) months with no violations. It's a pretty common thing for me to do, frankly,' she said.

'We are heartbroken by the news of this senseless tragedy, and we extend our deepest condolences to the families of Willie Simmons III and Alyssa Broderick.

'Willie was a senior at Elgin High School.

'He was an exceptional young man and leader among his peers. Strong, both academically and athletically, he represented the very best of Elgin ISD.

'He was the Captain of our football team; a friend to everyone he met; and most recently, recruited to play football for the University of North Texas,' Elgin School District said in a statement.

Broderick and his wife were in the midst of a bitter custody battle and divorce.

When he was released on bond, she pleaded with the courts not to remove his ankle monitor, saying: 'I'm afraid he will try to hurt me or my children, because these allegations have come out and he may lose his career.
