North Texas linebacker signee Willie Simmons is one of three victims of a mass shooting in Northwest Austin. 

While Austin Police have not confirmed the names of the victims, Elgin ISD confirmed that current student Simmons and former student Alyssa Broderick were among the three victims. The third victim has not been named as yet, but multiple reports claim it was the Alyssa's mother, Amanda Broderick. 

Simmons was captain of the Elgin High School football team and a member of the National Honor Society. He earned all-district honors twice and was set to become a member of the Mean Green this summer. Multiple reports say he and Alyssa Broderick were dating. 

"He was an exceptional young man and a leader among his peers," Elgin superintendent Dr. Jodi Duron told KXAN. "He represented the very best of Elgin ISD...The Elgin ISD community grieves the loss of these two young, promising souls." 

North Texas coach Seth Littrell Tweeted about the tragedy on Monday.

Simmons is just the latest tragic story in Texas high school football over the last several days. The same day, former Riesel football player Sabion Kubitza and Mart standout Jacob Ybarra were murdered, allegedly by former Houston linebacker Zamar Kirven.

A week earlier, Wyoming signee and former Lancaster standout Tony Evans was shot and killed at a hotel party in Dallas. Additionally, Utah running back Ty Jordan – a West Mesquite product – was killed in an accidental shooting on Christmas Day. 

Former Travis County Sheriff's Office detective Stephen Broderick, 41, was arrested on Monday morning in Manor in connection to the mass shooting after a 24-hour manhunt. Broderick served as a detective until June 2020, when he resigned after being charged with sexual assault of a child. He was released on $50,000 bail after spending 16 days in jail. 

After Broderick was arrested in June 2020, Amanda Broderick filed for divorce and a protective order that prevented him from going within 200 yards of their daughter, Alyssa Broderick, according to USA Today. 

"I'm afraid he will try to hurt me or my children because these allegations have come out and he may lose his career," Amanda Broderick wrote in a statement at the time. "Stephen has prior military experience and is SWAT trained. If he wanted to hurt someone, he would know how."
