The murder trial continues in Cobb County against Matthew Lanz, a Georgia man accused of killing a beloved firefighter and his wife.
As CrimeOnline previously reported, Lanz is accused of fatally shooting his neighbors, Justin and Amber Hicks, in 2021. He’s also facing a cruelty to children charge after fleeing the couple’s Acworth home, leaving their 2-year-old in the residence alone for hours.
On Tuesday, the prosecution played police interviews with the defendant’s parents, Scott and Theresa Lanz. Theresa Lanz said that her son had been seeking mental help, while his father said he had been exhibiting unusual behavior.
“He (Matthew) was hearing things, seeing things, believing things that weren’t true,” Scott Lanz said.
In October, a forensic psychologist told the court that Lanz suffered from schizophrenia, but a judge found him competent to stand trial, Court TV reports.
Both parents told investigators that Lanz and his brother, Austin Lanz, had been obsessed on the Hicks’ home, but appeared stunned when they learned that Matthew Lanz had killed the couple.
In April 2021, Austin Lanz broke into the home before the Hicks bought the property in September 2021. Months later, he took his own life after killing Pentagon police officer George Gonzalez, 37.
Theresa Lanz said that she had “never even met them,” referring to the Hicks family.

The prosecution told the court that DNA evidence and security footage placed Matthew Lanz at the crime scene, along with DNA evidence on a firearm.
Prosecutors showed the court the security footage of Lanz driving around the Hicks’ Acworth property on November 17, 2021, the same night they were murdered. The video also showed him walking around the property.
According to Atlanta’s News First, Justin worked over six years as a Cherokee County firefighter. Amber was an audiology assistant. The couple had a 2-year-old son.
Investigators said they found the toddler inside the home, soaked in blood, crying, and trying to cuddle the bodies of his deceased parents.

A few days later, police arrested Lanz after he allegedly broke into a Sandy Springs residence. When an officer responded to the scene, Lanz reportedly stabbed the officer several times in the neck and back; another officer then shot him.
Matthew Lanz’s defense lawyer has claimed that Lanz thought he was being “set up” by government agencies, such as the CIA and FBI.
Lanz requested a bench trial, meaning a judge will render the verdict.
The trial continues. Check back for updates.
