Czechs seek American in slaying of 4

BRNO, Czech Republic — An American man is suspected of killing a family of four and is on the run in the Czech Republic and probably armed, officials said Thursday.

The bodies of the victims, identified by neighbors as a married couple and their two sons, were found by firefighters as they battled a blaze in a house in Brno, the country’s second-largest city.

Jaroslav Mikoska, a spokesman for the fire department, said rescuers immediately realized that ‘‘a violent crime had likely been committed there.’’ The fire did not badly damage the house.

Brno police spokeswoman Petra Vedrova identified the suspect as Kevin Dahlgren, born in 1992, and released his photograph. A Facebook page showing the same photograph says that Dahlgren is from Palo Alto, Calif., and lives in Brno.

Czech public television reported that Dahlgren was the nephew of the parents. Police did not immediately confirm that relationship.

A local band, Ukulele Orchestra jako Brno, confirmed that two of its members were among the victims but declined to comment further.

Dahlgren’s Facebook page contained a link to the band.
