Brno/New York, Aug 25 (CTK) – A U.S. court rejected an appeal of Kevin Dahlgren against the decision on his extradition to the Czech Republic where he is suspected of a four-fold murder, Irena Valentova, from the Czech Foreign Ministry’s press section, told CTK Tuesday.

However, U.S. citizen Dahlgren may turn to a higher level court, asking it to suspend his extradition.

A court in the United States previously decided that all extradition conditions had been met.

However, Dahlgren filed a complaint questioning the legitimacy of his custody in the United States. He has been in custody since May 2013.

Though the complaint was turned down, Dahlgren appealed the verdict and the court keeps dealing with his appeal.

Dahlgren supposed that he cannot be extradited before the decision of the legal character of his custody was made.

However, according to Tuesday’s verdict, he can be extradited to the Czech Republic without waiting for the verdict about his U.S. custody.

The U.S. Department of State will make the final decision on Dahlgren’s extradition since it must give consent to it.

The Czech police suspect Dahlgren of having killed his cousin, her husband and their two sons in Brno in May 2013. The motive of the murder is unknown. He pleads not guilty.

After the murder, Dahlgren took taxi to reach Vienna, from where he left for the United States. During the flight, the Czech authorities issued a warrant for his arrest, based on which he was detained by the FBI on his arrival at the Washington airport on May 23.

If extradited and found guilty by Czech courts, Dahlgren would face life imprisonment. If the United States refused to extradite him, he would escape punishment.
