STERLING, Kan. — In taking his own life, David Madden may leave many questions unanswered. Authorities are still questioning witnesses about the shooting of two law enforcement officers in Rice County. Additionally, there are many unknowns about Madden’s connection to the disappearance of an Oneida, Illinois, woman more than three years ago.

Madden was a person of interest and even a suspect in the disappearance of Megan Foglesong, who was last seen in December of 2015 in Alden, Kansas. On Tuesday, the KBI stated that the active warrant against Madden that triggered Monday’s shooting was not connected to the young woman’s case.

A Facebook page called “Bring Megan Home” that was started by friends and family of Foglesong had postings about the shooting and press conferences connected to the case. Many on the page have long believed Madden was connected to the woman’s disappearance, but no arrests were ever made. However, the KBI did execute a search warrant at Madden’s home in 2017.

According to the missing person’s web site “The Charley Project,” Madden and Foglesong dated off and on.  They had broken up several times but kept reconciling. Foglesong told two friends that if she ever disappeared, Madden was probably the one responsible.

The website says that on November 30, the day of Foglesong’s last Facebook activity, she replied to a message from a friend and said she was at Madden’s house. On December 1, Madden told the local sheriff that he had caught Foglesong stealing from him and they got into an argument and she left.

On December 7, Foglesong’s phone sent a text to a friend, saying “I’m fine.” Her friend is not sure whether she sent the message herself. One of Foglesong’s friends said she got a call from her, asking if she could come pick her up. Foglesong said she was walking along a rural road in the rain. Her friend was unable to help her.

The site also says Madden had previously dated Foglesong’s mother, Pam Lewis. Lewis later stated she’d been told Foglesong left for Colorado with one of Madden’s friends. She said she doesn’t believe Madden was involved in her case and thinks that the friend Foglesong supposedly went to Colorado with was responsible.

Calls made to the KBI for an update on the investigation into Foglesong’s case were not returned as of Tuesday evening.
