Two men, including one whose life sentence was commuted by then-South Dakota Gov. Kristi Noem, have been charged in the death of a 14-year-old girl whose body was found in a rural area five days after she went missing in March.

McKenna Wendel was reported missing March 13 and last seen alive in her hometown of Sioux Falls early on March 14. Her body was found outside Brookings, an hour’s drive north of Sioux Falls, on March 19.

Wendel’s uncle, Mark Milk, 51, also of Sioux Falls, now faces five counts related to her death. Milk was almost three decades into a life term on a manslaughter conviction when Noem commuted his sentence in 2023.

Wendel was raised by her grandparents, loved animals and had a “vibrant personality and a zest for life,” according to her obituary. She and her grandparents were Rosebud Sioux Tribe members and attended powwows often.

“She loved the singing and the beautiful sounds of the drums,” her obituary read.

Details about Wendel’s death remained thin as authorities who announced the charges in a Sioux City, Iowa, news conference Thursday kept close what they knew to protect their investigation.

Authorities have said an autopsy was done, but the findings have not been released. The cause and manner of Wendel’s death would not be released yet per Justice Department policy, said Leif Olson, U.S. attorney for northern Iowa.

Milk faces five counts including possession with intent to deliver cocaine that caused Wendel’s death. He is also charged with transportation of a minor with the intent to engage in criminal sexual activity, according to court documents.

Jon Rogness, 38, of Brookings faces conspiracy and accessory charges in an alleged attempt to cover up the crimes. The counts against the men were the “most serious, readily provable” charges and all originated in Iowa, Olson said.

“This is a horrific case,” FBI special agent Gene Kowel said. “There are no cases that we investigate that are more heart-wrenching and more tragic than the ones that involve children or the death of a child.”

Court records showed no lawyers listed for Milk and Rogness, and no relatives could immediately be located through phone records and social media to speak on their behalf.

In February 2023, Noem commuted Milk’s life sentence for a manslaughter conviction in an October 1993 stabbing death. Milk, then 19, had been involved in several altercations in the city of Winner that ended with the death of Shawn Peneaux, according to records.
