    No evidence escapes the fish forensics team.

    Just hours after the U.S. Supreme Court declined to force Illinois to increase its anti-carp efforts, the Army Corps of Engineers says they've found two samples of carp DNA in Lake Michigan.

    The finding indicates the invasive fish has already breached the lake.

    The two samples, according to the Chicago Tribune, were found in Calumet Harbor a half-mile north of the Calumet River and in the Calumet River north of the O'Brien Lock.

    The samples were collected Dec. 8, and the Corps says two earlier tests didn't report positive results for carp DNA.

    Just last week the Corps said that carp DNA was found in the Chicago River near the Wilmette pumping station north of Chicago.

    According to a release from the eDNA project at Notre Dame, which performed the sampling, there's no known correlation between the number of positive samples and the quantity of carp.
