WINONA, Minn. - Authorities believe there might be foul play in the disappearance of 26-year-old Madeline Jane Kingsbury, who was last seen on Friday.
In anews conference Wednesday morning, Winona Police Chief Tom Williams called Kingsbury's disappearance "involuntary" and "suspicious."
"We are all concerned for her safety," Williams said.
Kingsbury's family is offering a $50,000 reward for information leading to her whereabouts.
Police say Kingsbury was last seen Friday morning dropping her children off at day care shortly after 8 a.m., with the father of her children in her dark blue 2014 Chrysler Town and Country van.
She didn't show up for work at Mayo Clinic in Rochester or pick up her children later in the day.
Williams said the father of Kingsbury's children told police he left Kingsbury's home driving her van around 10 a.m., but didn't see her when he returned later that day.
Police searched the van and Kingsbury's home, where they found her phone, wallet, ID and a jacket she had worn earlier in the day.
