Not based off of what the wiki article shows as being Crimean Gothic. The only definitive examples it shows are those that follow closely to Gothic and have minor German influences. It merely states that as a possibility, Crimean Gothic could not be a direct descendant, but instead an adopted and adapted language.
I tend to be leary of wiki articles on minor languages, especially in this case, given it was for along time a very short article.
That said the article states that the primary documenter was Flemish and that their might have been some influence in his documentation (like finishing a word you don't have the full spelling of using your own similar language); as to Biblical Gothic, it simply states that they had some similarities but it's widely accepted they were unrelated.
While I don't have the research myself, I do know a fair bit about it since my boyfriend is really interested in the Crimean Goths.
