I’m not sure what this is about but use these for at least the first part of the sentence(s).
2) Ronnie Bigs did not commit fraud, (You write the rest)
3) Bigs didn’t steal 2.6 million dollars, he (You write the rest)
4) He didn’t run away to Madrid, he (You write the rest)
4) A police officer didn’t recognized him in Australia. (You write the rest)
Of course you have to add more things, as I don’t know much of the story, and I’m not sure if the teacher wants more than one sentence.
Hope this helps!
