Mandan police responded to gunshots early Thursday morning, but say the shots are unrelated to a recent quadruple homicide.
In a press release, Mandan police said an officer was on patrol when he heard two gunshots at 1:42 a.m. Thursday. He found two people who also heard the shots and also saw a vehicle leave the area.
The officer found a bullet hole in the front door of a home on the 1000 block of Fourth Street Southwest in Mandan, according to police.
No one answered the door on Thursday afternoon at the house with a bullet hole.
Neighbors said they’re concerned about a lot of police activity they’ve observed at that house, which is one block west of Mary Stark Elementary School.
“It used to be such a safe neighborhood,” said one neighbor who declined to give her name, citing concerns for her safety.
Police reported no signs of injuries nor located any suspects.
"This case does not appear to be related in any way to Monday’s homicides," the police statement said.
Four people were found killed Monday morning at RJR Maintenance & Management, just off Memorial Highway in Mandan. Mandan Police Chief Jason Ziegler said their deaths are a "multiple homicide."
Ziegler identified the deceased as RJR owner Robert Fakler and employees Adam Fuehrer and William and Lois Cobb.
Authorities on Thursday night arrested Chad Isaak, 44, of Washburn, on suspicion of four Class AA felony counts of murder in connection with the homicides.
The gunshots are under investigation.
Mandan Police Deputy Chief Lori Flaten said police don't believe the gunshots are related to recent shots fired in Bismarck during the week of March 18.
