The killer's experience is very similar to that of old Ke Rong. Both are identity murders. They have been absconding for many years, but they are doing well.

After ruining other people's lives, they lived a comfortable life.

How did the killer escape for 28 years? How did he get caught?

Ma Jigang, 1966, from Nanjing, Jiangsu. 1On March 20th, 992, Ma Yungang went out for a walk after eating.

His family lives in Shigu Street, which is 10 minutes walk from Nanjing Medical University. That night, as soon as my mother walked past Southern Medical University, the devil walked into the school gate.

At that time, the management of the school was not as strict as it is now, and people outside the school could enter at will.

Ma Jigang walked into Southern Medical University and came to the middle of a teaching building to recite words. Through the window of the classroom, he saw a girl in a red sweater teaching herself.

Lin Ling, 22, is a senior at Southern Medical University. She will graduate in a few months.

Lin Ling comes from an academic family. Her father graduated from Tsinghua University and her mother is an intellectual.

In the 1990s, university was a luxury for many people. Although Lin Ling's family is rich, she still concentrates on her studies. Although there is no one else in the classroom, Lin Ling is still studying hard.

Ma Jigang's education level is very low. After graduating from junior high school, he entered the society very early.

After seeing Lin Ling, he suddenly had a wrong idea. In Ma Jigang's view, a literate person's personality, style and behavior are definitely different, and he wants to experience it.

Ma walked around the teaching building and found no one else, so he boldly walked into Lin Ling's classroom.

Ma Jigang stepped forward and said, "Sister, come out with me."

Lin Ling, who was absorbed in reading, was startled by Ma Jigang's voice. She looked up at Ma Jigang and said, "I don't know you. Leave now. "

Ma Jigang wouldn't give up and wanted to keep pestering, but Lin Ling ignored him and concentrated on reading.

After Ma Gang left the classroom, the more he thought about it, the more unwilling he became. He just found an iron pipe from the outside and walked back to the classroom. Ma Jigang dangling in front of Lin Ling with an iron pipe in his hand, trying to scare her. "Come out with me," he said.

Lin Ling was a little scared to see this situation. She said, "Do whatever you want, don't leave a message, I'll shout." . At the same time, Lin Ling got up to leave.

Without saying anything, Ma Jigang punched his pipe on Lin's head and got it under control. Then Ma Jigang dragged Lin Ling to a remote place outside the teaching building to invade.

In Ma Jigang's violence, Lin Ling strongly resisted. Ma Jigang simply hit Lin Ling on the head with an iron pipe again until Lin Ling stopped resisting.

After Ma Jigang went on the rampage, he saw Lin Ling lying on the ground and left without thinking. Walking on the road, Ma Jigang was a little uneasy and turned to see if Lin Ling got up. Did she call the police?

However, when Ma Jigang returned to the crime scene, he found Lin Ling lying on the ground. He went to check, only to find that Lin Ling had no heartbeat.

Ma Jigang's mind suddenly went blank. To cover up the murder, he opened the manhole cover of the sewer and put Lin Ling in.

Ma Gang was about to leave after all this, but he met two security guards patrolling the school. When the guards saw Ma Jigang, they thought he was a thief.
