TIMELINE: What led up to double murder of Cherokee County firefighter, wife?

COBB COUNTY, Ga. — An Acworth man is facing 43 charges across two counties after a bizarre crime spree in which police say he shot couple who lived next door to death and stabbed a Sandy Springs police officer.

Matthew Lanz, 22, was arrested on multiple charges in Fulton County and faces murder charges in Cobb County.

Police said Lanz shot and killed Cherokee County firefighter Justin Hicks and his wife, Amber, in their home in Acworth before breaking into a home in Sandy Springs a few days later. When police responded, Lanz stabbed the officer and was subsequently shot by another officer.

Lanz was taken to jail and the officer has since been released from the hospital.

Channel 2 Action News learned over the weekend that the Lanz family lived directly next to and shared a backyard fence with the home on Verbena Drive where the Hicks family lived.
