With no progress finding Stacy Polenske, police searched the area where her car was found on Thursday morning.

Polenske’s car was found early in the week on the east side of town, just outside of the city limits, near a swampy area.

Police conducted a search on foot and by motor vehicle on Thursday morning — south of U.S. Highway 30 and north of I-80.

Sheriff’s deputies, Union Pacific police officers and Nebraska state troopers assisted. A helicopter will also fly over the area, Police Chief Dan Hudson said. The chopper was initially grounded due to weather.

Hudson said no evidence was found during the morning search.

Polenske, 51, is a white female with blond/brown hair and blue eyes.

She was last seen in North Platte on Sept. 30. She has a medical issue that causes her to be disorientated and she experiences blackouts. She has no immediate family, just a roommate, police said.

Polenske’s vehicle was found Monday, Oct. 1, according to an endangered and missing person alert issued by the Nebraska State Patrol. She does not have her cellphone or medications, police said.
