UPDATE: After a more than 5-hour standoff police locate the man inside his home.

At 8:06 p.m., the suspect was found dead in the main level room of the home. Police say it appears it was self inflicted gun shot wound.

Officers say around 5:09 p.m. they heard several gun shots go off inside the home. That’s the last they heard of anything coming from inside the home.

Before they found the man dead, officers opened the main door with a bearcat to breach the front door, that’s when they say a strong odor of gas came out of the home. Police used cameras, and a robot to attempt to locate the man.

Officers say they broke several windows in an attempt to find the man. Police say every time they broke a window, the smell got stronger.

They called MDU to the scene because of the constant flow of natural gas.

After locating the man, police used a gas meter to test the gas levels and shut off the valve in the basement.
