What is the author's perspective in the book, The Other Wes Moore: One Name, Two Fates?

The book is told from the point of view of the author, even when he is telling about the events that happened in Wes’ life. When he writes about his own life, he writes “I” and “me.” When he writes about Wes’ life, it is third person. But, it is not a detached third person. It is not omniscient, either. Most of his information comes from one-on-one interviews, so he is able to tell the story as if he is there. He is able to describe the characters’ thoughts because the reader is led to believe that the author has interviewed this person. However, the final chapter describes the attack that left Prothero dead. In this case, the perspective changes. It is a distant third person, without any knowledge of the characters’ thoughts or specifics about actions. This information, presumably, came from court documents. Therefore, the jewelry store robbery reads as if it is a re-enactment.
