Suspect has just emerged naked from the sewer.
I just wonder why it is "naked" instead of "nakedly". Normally it's the adverb that modifies a verb. Such as: "I went there happily." It would be wrong if you say "I went there happy."
Is it just because it's colloquial, and couldn't be used in formal English? But the quoted sentence seems right to me.
