After hours of searching in the cold for a missing Lancaster County man, officials called off an unsuccessful search around 10:30 p.m. Tuesday.
They were looking for 46-year-old Michael James Urenovitch from West Earl Township.
Fliers hanging around the area say he was wearing a black hat and jacket, blue pants black shoes and glasses.
The flier also indicated that Urenovitch may be confused. Police say there is concern because he suffers from a medical condition.
Officials say he left his home at the Eagleview Estates development around 3 p.m. and did not return. The search began around 4:30 p.m.
Over 100 people, including those from volunteer rescue groups, joined the effort.
First responders were seen using rescue dogs and snowmobiles to search fields off of Tobacco Road, near a housing development.
Officials say low temperatures make time a critical factor.
"Anytime you that someone goes missing you want to be looking for them as soon as you can so that the trail doesn't go cold. Time is of the essence. The colder it gets the harder it gets for the person we are looking for as well as fire department and search team," said Phil Hursh, public information officer for the West Earl Fire Company.
There was no immediate word on whether the search would resume Wednesday.
