The brother of "The Dark Knight" director Christopher Nolan is facing murder and kidnapping charges after being arrested in Chicago.

According to the Chicago Sun-Times, Matthew Francis Nolan, 40, who was arrested in February for the kidnapping and murder of Florida businessman Robert C. Cohen in Costa Rica in 2005, is also being investigated for an unrelated $700,000 bank-fraud scheme.

As for the murder in Central America, Nolan allegedly schemed with accomplice Douglas Mejia to recover $7 million that Cohen owed to another Florida man.

Reports say Nolan met Cohen at the hotel under the pretense of doing business with him. An accomplice kidnapped Cohen and then the schemers tried to extort money from the businessman's family.

Costa Rican authorities then claim that when that didn't work, the men killed Cohen.
