U.S. authorities have arrested a man wanted in the murder of four members of a family in the Czech Republic, Czech police said on Friday.
The man, identified by police as Kevin Dahlgren, has been searched for since four bodies were found in a family house in the city of Brno, the nation's second-largest city about 120 miles southeast of Prague, on Wednesday evening.
"Kevin Dahlgren, charged with quadruple murder, was arrested last night," after landing in Washington D.C.'s Dulles International Airport, regional police chief Leos Trzil said on Czech Television.
Police investigator Antonin Hrdlicka said the pilots and crew of the flight from Vienna were informed that the suspect was onboard, the Associated Press reported.
Czech Television reported Dahlgren was a relative of the victims, a married couple and their two sons.
The Facebook page in his name, set up only earlier this month, says he was from Palo Alto, Calif., and was offering English lessons in Brno.
