MANSFIELD, Ohio -- Police in Mansfield say the standoff has ended with a man who authorities described as a "survivalist."
Police say the end of confrontation came when David Parker opened fire on snipers positioned on a perimeter around his house, and a sniper from the State Highway Patrol returned fire, striking Parker. He died.
WCMH says authorities flooded the basement of Parker and believed he was in a bunker. His gas and electricity were turned off.
He lives in a residential neighborhood on the south side of the city and is described by police and neighbors as a "survivalist" and a "doomsday prepper."
He reportedly shot at officers and SWAT team members throughout the day Monday with bullets that pierced through bullet proof shields.
The standoff started when a gas company employee arrived at his home, reportedly to turn off the gas. Parker then pulled a gun on the worker and the standoff soon began at around 8:30 a.m.
Monday night, robots were sent up to the house, but he continued to open fire on authorities.
Police say it's not clear if Parker's home was booby-trapped, but they believe he has a bunker in his basement. It's not clear what types of weapons he may have.
