Columbia police have located items dated close to the time frame the remains of a woman allegedly killed by her husband might have been brought to the city-owned landfill.

Keith Alan Comfort is charged with murder for the death of his wife, Megan Shultz, who disappeared 13 years ago. Comfort confessed to the killing on Aug. 6 and said he put her body in a trash dumpster in the 1700 block of Amelia Street.

The police department and the Solid Waste Utility announced last week they would be conducting an exploratory dig at the landfill to try and pinpoint her remains. Police spokesman Jeff Pitts stated in a press release Wednesday that dated items discovered this week may bring investigators closer to the location.

“There is a need for additional exploration in the 14-acre area for any clues that will help us to more accurately define the correct area or areas which may warrant further investigation,” Assistant Police Chief Jeremiah Hunter said. “We are very thankful for not only the assistance that we have been receiving from the staff of the Solid Waste Utility but the incredible support from Megan’s family.”
