MILWAUKEE (CBS 58) -- The latest reward in the Nancy Guthrie case doesn't come from Arizona, but right here in Milwaukee. 

Attorney Michael Hupy, who is also the president of Milwaukee Crime Stoppers, says he's putting up a $100,000 reward for information in the case. 

It comes as the search for Nancy Guthrie reaches its third week. 

Savannah Guthrie posted an emotional message on social media Sunday, asking for her mother to be brought home. 

"Whoever has her, or knows where she is, it's never too late to do the right thing," Guthrie said. 

Eighty-four-year-old Nancy Guthrie was last seen on Jan. 31
