To see if detained immigrants are being locked up unlawfully for long periods of time, a civil rights group is seeking to get the Vermilion Parish sheriff to turn over documents on immigrants who've been jailed since 2009.
The Southern Poverty Law Center filed a lawsuit against Sheriff Mike Couvillon Wednesday. The group says the sheriff has refused to hand over the documents, citing privacy concerns.
The group charges sheriff's offices may be holding immigrants longer than federal law permits.
