On the morning of May 15, 2013, Aunt Liu was busy in the kitchen early. This morning, her son and daughter-in-law had an appointment to go home for breakfast. After waiting for a long time and seeing no one, Aunt Liu called the couple. As a result, both phones were turned off. Aunt Liu waited until more than ten o'clock. When the food was cold, she did not say anything about her son and daughter-in-law. Aunt Liu was a little panicked and hurried to her son's house. She pushed her son's door and found that the door was left unlocked. When she approached the door, she found no one in the living room. "What's the matter with you? Your cell phone is turned off!" Aunt Liu shouted loudly, but no one answered. She could only continue to walk to the bedroom. "What did I say you were doing?" Aunt Liu knocked on the bedroom door and asked, but no one answered. She pushed open the bedroom door and saw that the bed was clean and the couple was not at home. In addition, she did not find anything unusual at home. However, when she turned around and came out, the scene in the yard frightened her to disgrace. In the yard, the son's dog fell into a pool of blood. A blood hole was cut out of his head and thrown into the corner of the wall. The bricks beside him were covered with blood. Seeing that the ground was covered with blood, Aunt Liu collapsed with fear and called 110 to call the police.
