A man is facing capital murder charges after allegedly shooting and killing three individuals, including a 4-year-old girl, during a carjacking incident at a Target store in Austin, Texas on Monday.

The Austin Police Department reported that 32-year-old Ethan Nieneker was taken into custody on Monday and is now charged with two counts of capital murder along with one count of first-degree felony murder.

Police identified the victims who were killed as Hector Leopoldo Martinez Machuca, Adam Chow and Chow’s 4-year-old granddaughter.

Police stated that officers were dispatched in response to multiple shooting reports at the Target parking lot near Research Boulevard around 2:15 p.m. Upon their arrival, they discovered Machuca in the parking area.

Police said Nieneker also attempted to break into a Waymo vehicle, but after failing to do so, he drove off in the Volkswagen.

A little before 3 p.m., authorities received a call reporting a naked man walking through a backyard on La Casa Drive and entering a portable toilet before running away. This happened after an acquaintance of Nieneker informed police that Nieneker had thrown a brick through his window on the same street.

Upon reaching the scene, officers witnessed Nieneker walking naked on Montclaire Street. After he did not comply with orders, they used a taser on him and detained him.

The officers also reported that they found matching clothing that was seen on the suspect inside the “porta potty.”

“We have three people that are deceased. This is a very sad day for Austin,” stated Austin Police Department Chief Lisa Davis on Monday. “It’s a terrible day for everyone, and my sympathies are with the families.”

A preliminary investigation found the suspect has a history of mental health issues, the chief said. 

Davies told reporters the suspect has a rap sheet as well as emergency detention holds.

Target employees directed shoppers out of the back of the store, a source tells FOX Business.

“We are devastated by the violence that occurred today at our store in Austin, Texas. Our hearts are with the families and loved ones of those who lost their lives, our team in Austin and all those impacted by this tragedy,” Target said. “We are working with law enforcement as they conduct their investigation and are grateful to the first responders who acted quickly at the scene. In the days ahead, we will continue partnering with law enforcement and will be providing support resources, including grief counseling, to our team.”
