FBI spokeswoman Laura Eimiller confirmed Thursday that warrants were served in the cities of Corona and Ontario. She says it's an investigation stemming from the San Bernardino attack, but she declined to elaborate.
Eimiller says the U.S. attorney's office is expected to issue a statement.
The December attack on a gathering of San Bernardino County environmental health workers was carried out by a co-worker and his wife. In addition to those killed, 22 were wounded.
The shooters died in a gunbattle with police.
