KESHENA, Wisc. (SPECTRUM NEWS) — Robert Lyons was last seen riding a white ATV near Keshena more than three years ago.

He went missing that day and hasn’t been seen since.

But his mother, Doreen Nahwahquaw, thinks about him daily.

“It’s been three years, one month and two weeks,” she says. “He was a really good family man. It’s been really hard.”

Police haven’t forgotten about him either. 

Lyons’ one of three missing persons cases that Menominee Tribal Police continue to investigate.

The department — and others — continue to look for answers of what happened to Lyons as well as Katelyn Kelley who disappeared in June and Lisa Ninham who vanished in 1980.  

They also continue to pursue leads in the 1986 murder of Rae Elaine Tourtillott.

“Someone knows something out there,” says interim police chief Richard Nicotee. “We would like them to come forward so the family can have peace.”

The cases were highlighted at a press conference Wednesday that included Wisconsin Attorney General Josh Kaul, who discussed the recent formation of a state task force focused on missing and murdered Indigenous women.

“This is an issue that is nationwide. It is impacting tribal communities across the United States, and Wisconsin, unfortunately, is no exception to that,” he says. “There have been murdered and missing Indigenous women in tribes across the state of Wisconsin, and we need to something about that.”

The tribe also announced a pair of $5,000 rewards for information in the Lyons and Kelley disappearances. The Federal Bureau of Investigation is also offering a reward in the Tourtillott case.

People with information on any of the cases can call Menominee Tribal Police at 715-799-3881.
