Answer:
The last to go to sleep was Nancy and her last entry was about Bobby and how he was liked.
Explanation:
The Clutter family, parents Herb and Bonnie and teens Kenyon and Nancy, were wonderful, church-going and happy family residing on their farm in Holcomb, Kansas. The narrator follows the Clutters through the event pertaining to their last day on earth. Perry Smith and D ick Hickock, also known as the killers, slaughtered them late that night.
Perry and D ick left after the murders and made it to Mexico. Kansas lawman Alvin Dewey and his four special agents led the manhunt for the killer(s).
Truman Capote received first-class service from the KBI and Mr. Dewey, its lead detective on the case. Mr. Dewey gave the author access to the diary of 16-year-old Nancy Clutter which was her final entry logged only moments before the unexpected happened -
two strangers invaded her home in late 1959 and murdered her, her brother and her parents. Mr. Dewey opened the KBI's case file to Mr. Capote. He pressured press-shy locals to cooperate with the author and granted him important access to the killers. Mr. Dewey even helped Mr. Capote, a man from New York with no home in Kansas, obtain a Kansas driver's license.
