New clues may be emerging about a man missing from Mazomanie since June 30.
Dane County sheriff's deputies are out in southwest Sauk County near Lone Rock Monday investigating new tips connected with the case.
"Several people from both the Sauk County Sheriff's Office and Dane County Sheriff's Office are out here searching an area. They've set up a perimeter inside this wooded area just by the river, and they're working in hopes that we can find some evidence," said Elise Schaefer, of the Dane County Sheriff's Office.
Matthew J. Graville, 27, of Mazomanie has not had contact with his family in over four months.
Because Matthew has Asperger’s syndrome, he is considered endangered.
The Dane County Sheriff’s Office reported Graville missing in October and has since received tips, including a tip suggesting Graville might be residing with a family in the Madison area.
Detectives have since contacted the owner of the car and confirmed Graville was not with them.
Tips from the public are prompting the Dane County Sheriff’s Office to seek more information about a family who might be caring for a missing Mazomanie man.
