Almost always sentence fragments are caused by the writer using a period in a sentence where all that was really needed was a comma. Example fragment: He always felt at home in the city. Having spent so much of his childhood there. ("Having spent so much of his childhood there." is the "fragment," because it has been "broken off of" the sentence it belongs to.) The sentence should have been, "He always felt at home in the city, having spent so much of his childhood there."
