Prior to encountering Lanz at a home on Cameron Glen Drive, Sandy Springs PD said multiple residents in the area called police to report home intrusions.
According to the GBI, when officers made contact with Lanz, "he suddenly attacked one of the officers, stabbing him repeatedly in the back and neck area."
Sandy Springs Police said Friday the officer was "doing well" after treatment for the stabbing wounds.
In the murder of the Hicks, Cobb County Police said earlier this week the couple was believed to be shot to death and that they did not have evidence the suspect had stayed in the area.
Family and friends described the couple as childhood sweethearts who grew up down the street from each other.
"They loved everybody. They would do anything for anybody. And their baby was their world. Oh they loved Jacob. He was their world," Amber's cousin Kristyn Bauer said.
Sandy Springs authorities are asking anyone with additional information on this case to contact Detective Needham at CNeedham@SandySpringsGa.Gov or by calling 770-551-2563. They are also asking residents that live in the vicinity to check their door bell cameras or exterior surveillance cameras for anyone suspicious captured Friday, Nov. 19 between the hours of 6 a.m. and 8 a.m..
Additionally, police confirmed Matthew Lanz is the brother of Austin Lanz, a 27-year-old man who was shot and killed by law enforcement in Washington, D.C. in August after stabbing a Pentagon Police officer to death.
Arrest records showed that in April this year, Austin Lanz was taken into custody on criminal trespass and burglary charges for entering his neighbor's house - the same home the Hicks recently moved into.
The Washington Post reported on Austin Lanz's alleged harassment of the couple that lived in the home before the Hicks.
Prior to being arrested for entering the home, Austin Lanz had been given a warning for allegedly "leaving inappropriate photographs and notes in the mailbox of said victim's residence."
Austin Lanz was later charged with two felony counts of aggravated battery of an officer for allegedly attacking deputies while being processed at the Cobb County Adult Detention Center.
