A person is in custody following the possible abduction of an Illinois couple from a home about 140 miles west of Chicago in rural Erie. 

Early Thursday, the FBI announced it had taken a person into custody. The couple was found alive and in good health. 

Late Wednesday, federal agents, along with the Whiteside County sheriff's office, asked for the public's help in the investigation of the possible abduction of a man and a woman. They did not release details about what happened, but they believed whoever possibly abducted the couple did so for financial reasons, according to a news release. 

Agents were searching for a two-tone silver Chevrolet Caprice that could have possibly been involved in the incident, according to the release.
