The famous casino in Las Vegas, Nevada, the United States, on the evening of October 1, 2017, the worst shooting in the United States in 25 years occurred, which caused more than 100 innocent people to be injured. The incident occurred at a country concert near Mandalay Bay Hotel. This incident became a hot topic for everyone. I used newspapers, cardboard, second-hand books and sewing tools as inspiration for this incident to do some collage creation. The name of this book is as mysterious as the murderer ’s motive. I hope that through this book, we can call on all sectors of society to pay more attention to social violence and reduce such unnecessary tragedies.
