Search resumes for Ransom woman
12/11/2010
With a slight temperature warmup Friday, the search for Tanya Shannon of Ransom, who’s been missing since Sunday, resumed on the ground, in the air, and by additional K-9 units from as far away as Wisconsin.
More than 40 people — 10 from the La Salle County Ground Search and Rescue team returned to retrace their snowy steps over the area near the Exelon Nuclear facility in Brookfield Township Friday. The area was previously examined Sunday, Monday and Tuesday by a total of more than 170 trained volunteers and professionals. Shannon, the mother of four daughters, has been missing since a Sunday morning single-car crash that killed her husband, Dale.
As of press time Friday night, no trace of Tanya had been discovered.
Sheriff Tom Templeton confirmed to The Times Dale Shannon was not wearing a seat belt at the time of the crash, in which a county deputy found him dead behind the wheel of a 2001 Dodge Neon at 1:45 a.m. Sunday. Templeton said the vehicle’s airbags did not deploy despite a hard rear end collision with an electrical pole.
Dale, 41, died instantly in the accident from a severe neck injury, according to the coroner’s office.
Templeton said the passenger side door was ajar, but snow piled up against it prevented it opening much further and so, it is presumed by authorities that Tanya crawled out of the Neon over the stick shift, her deceased husband and out the driver’s side door before she disappeared into the dark frozen farmlands. Her working cell phone was found in the car. Dale’s cell phone has not been recovered.
La Salle County Ground Search and Rescue Chief Steve Smith said seven K-9 units from various North Central Illinois locations were on the targeted scene in Brookfield Township Friday, including one unit from Wisconsin.
Smith confirmed some of the canines were cadaver dogs trained to seek out decomposing bodies opposed to search dogs, which are skilled in following a scent taken from personal items (clothes, etc.) of a person living or dead.
Templeton said he appreciated the numerous offers during the last few days by local residents wanting to volunteer for the massive search, but he insisted it was best to leave the efforts to the trained people on the scene who have experience in such operations.
It was not revealed if the search will continue through the weekend, as a blast of cold weather is predicted to descend on the area.
