TOWN OF GENESEE, Wis. - Waukesha County authorities have found the bicycle of a missing girl but say there are still no signs of the 15-year-old who was last heard from Tuesday.

Kathryn J. Stalbaum missed her school bus Tuesday morning and texted a friend she'd ride her bike to Kettle Moraine High School instead. She never arrived.

Sheriff's Inspector Eric Severson said Thursday her teal bicycle had been found across the street from a hospital in Waukesha. He said there were no immediate signs of foul play.

Authorities searched a nearby retention pond for evidence but found nothing. The search continued Friday.

Severson says the girl's disappearance is out of character for her.

Investigators have reached out-of-state family members and have contacted local hotels, bus and cab companies. Right now there is a $1,000 reward for information that leads to finding Stalbaum. Authorities have received about 150 phone calls, but they're not getting the sort of leads they hoped for.

Police are also asking people to download the teen's picture on their cell phones, and to send it to friends to keep her case top of mind.
