A Rice County, KS, undersheriff was shot in the neck and critically wounded Monday and the sheriff was shot in the leg in a related incident. The suspect was found dead of a reported self-inflicted gun shot after a standoff with law enforcement. The suspect's father was also found dead at the scene.

The Kansas Bureau of Investigation says that when suspect David L. Madden shot the Undersheriff Chad Murphy, a woman and a child accompanied him in the vehicle near the Sonic in Sterling. Madden then fled the area and drove to his home in Alden to retrieve guns and ammunition. He then went to his father's home, where it is believed he fatally shot Thomas Madden prior to the sheriff and deputy arriving. Then, it is believed the woman left the scene. A short time later, Sheriff Bryant Evans arrived. He was shot at 5:40 p.m. in the leg.

After Sheriff Evans was shot, Madden reportedly exchanged gunfire with additional responding law enforcement officers. Over the next several hours, the Kansas Highway Patrol's Special Response Team, and the KBI, the Barton County Sheriff's Office, the Reno County Sheriff's Office, the Wichita Police Department, the Rice County Sheriff's Office, the Sterling Police Department, the Lyons Police Department, and many other area law enforcement agencies, attempted to safely determine the suspect's location in the home.

They first located the body of Thomas Madden. Then, at approximately 12:10 a.m., authorities located the body of David Madden, which ended the standoff.

"We know that he (David Madden) had warrants for his arrest, and he was more than likely trying to avoid the arrest, when the deputy approached him, when the undersheriff approached him. But again, a lot of that is still being determined, we'll never know what his true motive was now," said Steve Roseborough, Special KBI agent in charge. 

Undersheriff Chad Murphy is reportedly in critical but stable condition. Sheriff Bryant Evans was treated and released.
