PRAGUE — An American man accused of killing a family of four in the Czech Republic has been arrested in the United States, police said Friday.
Leos Trzil, regional police chief in Brno, said Kevin Dahlgren was arrested after the Czechs issued an international warrant.
Dahlgren was arrested by FBI agents at Washington Dulles International Airport, about 26 miles west of Washington, said FBI spokeswoman Lindsay Godwin.
The suspect fled to the United States after the victims — identified by neighbors as a married couple and their two sons — were found by firefighters who responded to a fire Wednesday in a house in Brno.
Police investigator Antonin Hrdlicka said the pilots and crew of the flight from Vienna were informed that the suspect was onboard.
Czech police said Dahlgren was born in 1992 and released his photograph. A Facebook page showing the same photograph says that Dahlgren is from Palo Alto, Calif.
Police spokeswoman Petra Vedrova said that all four victims were related.
A Czech public television station reported that Dahlgren was the nephew of the slain parents, but that was not confirmed by police.
A local band, Ukulele Orchestra jako Brno, said that two of its members were among the victims.
The band declined to comment further.
