Man accused of shooting Kansas officers a 'person of interest' in woman's disappearance

Posted: Updated:

The man accused of shooting the Rice County sheriff and undersheriff on Monday has been investigated as a person of interest in the disappearance of a Kansas woman in 2015. 

The Kansas Bureau of Investigation says Rice County Undersheriff Chad Murphy was shot and critically wounded around 5 p.m. Monday after attempting to stop a car driven by 37-year-old David L. Madden north of Sterling. Sheriff Bryan Evans and a deputy then pursued the suspect to a home in a nearby town, where the sheriff was shot in the leg in an exchange of gunfire.

Madden and his father were found dead early Tuesday morning following a standoff at a home in Raymond. 

A court document filed in February says that a KBI special agent indicated to an ATF agent that David Madden "was a person of interest in the disappearance" of Megan Foglesong. But that's where mention of Foglesong ends, leaving more questions. 

KAKE's Missing in Kansas Investigator Annette Lawless reports Madden had been in a relationship with Foglesong. 

The criminal complaint charges Madden with possession of an AK-47 machine gun, not Foglesong's case. 

The document, referencing a February 2017 investigation, says ATF agent Neal Tierney "is involved in an investigation regarding a missing person being conducted by the Kansas Bureau of Investigation (KBI) for a Megan Fogelsong [sic]."

KBI Special Agent Jeff Newson had contacted Tierney on several occasions to report that the KBI had received in formation on Madden, who was suspected to be involved with explosives and/or explosive materials. 

"SA Newson further indicated to SA Tierney that Madden was a person of interest in the disappearance of Ms. Fogelsong [sic]," the affidavit says.

Foglesong has been missing from her home in Alden since late November or early December 2015. 

The affidavit says that on February 22, 2017, Madden led authorities on a high-speed chase in Rice and Barton counties. He was later arrested after a standoff at his home in Alden.

The KBI and local law enforcement executed a search warrant at the home three days later, during which they found two wooden crates that contained two dozen pipe bombs. Another 24 pipe bombs, two military ordinance projectiles and other bomb making materials were found the next day. 

The KBI secured and retained custody of the home, "which is consistent with KBI investigations into missing persons and homicides," the document says.

Newson and another KBI agent returned to the home on March 9, 2017 and found an AK-47, a semiautomatic pistol and a regulated explosive item. 

While being interviewed by Special Agent Tierney, Madden admitted to making and lighting off pipe bombs and had been doing it since he was a kid. The affidavit states he also admitted to finding the AK-47 in Iraq when he was deployed with the Marines, and bringing it back knowing it was a machine gun. 

The affidavit obtained by KAKE News was signed on February 27, 2019. Kansas Department of Corrections records list Madden as an absconder as of February 11.
