MASON CITY, Iowa - Codie Matz, wanted in connection to a homicide investigation of his grandparents in Mason City, is facing a double murder charge after an alleged crime that stunned a neighborhood.
Matz, initially listed as a material witness, was taken into custody Nov. 7 near Bondurant, Iowa, and was taken back to Cerro Gordo County and is accused of killing 61-year-old Kenneth Hackbart and his wife, 64-year-old Kathleen Hackbart.
Police were looking for the 25-year-old Matz in connection to a homicide investigation at 327 27th St. SW in Mason City where two bodies were found.

Letha Markwardt, who lives in the neighborhood, was shaken by the news.
“I was just sitting here and I heard all this noise and it made me curious to see what's going on, and then I saw the police cars. I was very upset, wondering what in the world is going on,” Markwardt said.
She's lived on 27th street SW for more than 50 years, raising her kids in this neighborhood. She never thought police would come knocking at her door like this.
“It’s just kind of makes you sick to your stomach. You don't think that will happen around you, it upset me,” Markwardt said.
Kenneth and Kathleen Hackbart own the home and were later identified as the victims.

“It’s disturbing to think this sort of thing goes on, it just disturbs a person,” Markwardt said.

Area schools were contacted by Mason City Police after they found the bodies and described the witness might be armed and dangerous.
An email was sent to teachers by Mason City Schools that they were under a soft lockdown, meaning no students were allowed out of the building until dismissal. Mason City Police did not advise the lockdown and the email stresses authorities did not believe students were in danger.
“You never know what the person may do, where they may go, who they are friends with or may contact, etc,” captain Mike McKelvey said.
Police initially cautioned that Matz may be armed and suicidal.

The investigation began when police conducted a welfare check at the residence in Mason City's southwest side. Upon making entry, officers found two bodies.
