A $25,000 reward is being offered for a pair of fugitives linked to the violent abduction of a North Carolina man who was brought to Atlanta.

And a McDonald's meal receipt is what led federal authorities to the new suspects.

The FBI is leading a manhunt in the metro Atlanta area for Jakym Camel Tibbs, 21, and Quantavious "Kirkwood Quan" Thompson, who is either 18 or 19 years old.

Both have been charged with kidnapping in connection with the abduction of Frank Arthur Janssen, according to federal prosecutors with U.S. Attorney's Eastern District of North Carolina office.

Six other people, including a North Carolina inmate serving a life sentence, have been accused of planning Janssen's kidnapping.

Kelvin Melton, who was sentenced to life in prison for orchestrating a 2011 murder plot, is said to be the mastermind of the Janssen kidnapping. Prosecutors said he gave instructions from his jail cell using a contraband mobile phone.

Janssen's daughter, Collen Janssen prosecuted Melton's 2011 murder plot case.

Tiana Maynard, Jenna Paulin Martin, Michael Montreal Gooden, Jevante Price and Clfton James Roberts were all arrested and charged with kidnapping after Janssen was rescued by a special FBI kidnapping task force on April 10 from a southeast Atlanta apartment.

Prosecutors say Tibbs and Thompson drove a rental car to Wake Forest on April 5 along with two women, stopping along the way to eat at a McDonald's in Lexington, S.C.

Both Thompson and Tibbs were seen in video captured inside the restaurant, according to federal criminal complaints obtained by The Atlanta Journal-Constitution.

Later that morning Janssen was taken from his Wake Forest home, authorities said, after encountering a pair of women at his front door who attacked him with an electronic stun gun.

The suspects contacted Janssen's wife and threatened to chop him up and send his body parts back to her, among other things, and made demands regarding Melton, prosecutors said.

Investigators found the meal receipt from the Lexington McDonald's that apparently had been dropped during the kidnapping, prosecutors said.

A judge on Tuesday denied bond to the five Georgia suspects, and they remain in federal custody.

Thompson and Tibbs remain at large, U.S. Attorney's officials said, and are considered armed and dangerous.

Anyone with information on their whereabouts is asked to call the FBI at 1-800-225-5324.
