MADISON, Wis. -- The search continues for a missing University of Wisconsin-Whitewater student who vanished from downtown Madison last week.

The family and friends of Kelly Nolan spent the Fourth of July holiday passing out fliers at Elver Park as part of their ongoing effort to get the word out about the missing 22-year-old, WISC-TV reported.

Nolan has been missing since the early-morning hours of Saturday, June 23, when she was last seen in the downtown area. Nolan became separated from a group of friends on Friday, June 22.

On Tuesday, her family announced there would be a reward offered to anyone with more information, but details about the amount and who donated the money aren't being released.

Nolan is described as 5 feet 6 inches tall and weighs about 125 pounds. She has brown eyes and brown hair. Her sister said that on Saturday night, Kelly Nolan was wearing a green, sleeveless top with a scoop neck, a light pair of jeans, sandals with a heel, and carrying a slate gray purse.

Nolan's family and police are continuing to urge people to phone in tips to Crime Stoppers at 608-266-6014.
