MASSENA -- Another attempted illegal border crossing was foiled by Customs and Border Protection, leading to federal charges for one woman who sought to smuggle four illegal immigrants in the trunk of her car.

According to court documents, Cynthia Thomas, no age or address provided, attempted to illegally transport four Colombian citizens into the U.S. through the Massena port of entry.

Thomas allegedly picked up the five in a Cornwall, Ontario, parking lot before attempting to cross into the U.S. about 30 minutes later, documents state.

While attempting to cross at the port of entry, Thomas appeared nervous and did not make eye contact with officers when answering basic questions, according to documents.

When asked to lower the rear window of her 2002 Cadillac Escalade, Thomas became visibly nervous and began to shake, a CBP officer stated in the documents. 

Officers then inspected the trunk area of the vehicle, observing a blanket spread in the trunk area,  which then began to move when an officer touched it. The officer then removed the blanket and found the illegal migrants hiding in the trunk, documents state.

The individuals in the trunk were identified as Colombian citizens who were attempting to illegally enter the United States.

According to court documents, Thomas picked up the individuals in a parking lot in Cornwall and was to drive back to Cornwall to meet with an unidentified person who coordinated the crossing so she could be paid between $700 to $1,000 for each person transported.

Thomas was being held in federal custody prior to a detention hearing on Tuesday, Jan. 16.

Multiple attempts to reach Border and Customs Protection officials for further information were unsuccessful as of press time.
