True Crime Wisconsin, a new weekly podcast from WMTV 15 News, goes beyond the headlines to investigate the state's most haunting unsolved cases. Wisconsin has made national news for some high-profile crimes — but not every case gets that kind of attention. Some stories fade from the spotlight, and some are never solved.
Each week, WMTV 15 News digs into a different case from across Wisconsin, talking with the detectives and investigators still working to find answers, and the people who may hold the missing piece of the puzzle. The goal: bring renewed attention — and maybe new information — to cases that still need closure.
The case may go cold. The questions don't. New episodes drop every week.
The latest episode of "True Crime Wisconsin" investigates the disappearance of 43-year-old Leya Stewart. She was last seen on foot around 2 p.m. on July 4, 2023, on 43rd Street near 19th Avenue in Lemonweir Township, outside New Lisbon in Juneau County. Stewart left her phone, shoes and cigarettes at a friend's house, and her family says no one has heard from her since.
WMTV's Tabitha Bland sat down with Juneau County Sheriff's Office Detective Shaun Goyette, the lead investigator on the case, more than three years after Stewart vanished. Goyette describes the search, says much of the information investigators have received is hearsay and explains why the case remains a missing persons investigation. He asks hunters and visitors to report anything that looks out of place.
The episode also looks at the family's belief that Stewart did not leave the area alive. Anyone with information can call the Juneau County Sheriff's Office at (608) 847-5649.

Missing for nearly 80 years: Georgia Jean Weckler
On May 1, 1947, 8-year-old Georgia Jean Weckler was dropped off after school at the end of her family's half-mile farm driveway in the town of Oakland, near Fort Atkinson. She picked up the mail and has not been seen since. In this episode of True Crime Wisconsin, hosts Tabitha Bland and Mackenzie Davis talk with Jefferson County Sheriff's Office Det. Sgt. Ryan Viney about the search, a black sedan reported on Highway 12 and two ransom letters the FBI confirmed were hoaxes. They also cover a 1947 confession that was later recanted and a 2013 dig that found nothing. Georgia Jean's case is one of the oldest active missing child cases in Wisconsin.
