What caused Lin Ling to be killed and where did the murderer escape? Please follow Bian Xiao into the rape and murder case of South Medical University and explore the truth behind the case together.
On March 24, when the body was found, it was pressed face down in the sewer. Autopsy results show that Lin Ling died on March 20th, and was sexually assaulted by the murderer before his death. Semen was extracted from Lin Ling's body. Due to the limited testing conditions at that time, the DNA sample did not play a substantial role in the detection of the case, so the sample was retained.
According to the place and time of death, the police visited the campus to look for witnesses. On the night of the murder, two patrolmen found a strange man. Seeing that he stamped his foot while washing his hands by the pool, the security guard wanted to ask, and the vigilant suspect immediately climbed over the wall and left.
According to the description of the security guard, the police copied the portrait of the suspect and publicly offered a reward of 1000 yuan for the arrest of the suspect. Mobilize a lot of manpower and material resources to form a task force to conduct interviews and investigations. The number of people is as high as 1.5 million. Due to backward technology and limited investigation conditions, the murderer has never been found.
The mother of Lin Ling, the deceased, calls the public security organ every year on March 24th to inquire about the progress of case detection. As early as 2065438+June 2008, the Nanjing Public Security Bureau set up a leading group for the investigation of the "March 24th" homicide case, and deployed police forces to work in a centralized way to put into a new round of case investigation.
It is always the goal of Nanjing public security organs to solve the "March 24" case as soon as possible, safeguard legal dignity, give an account to the families of the deceased and safeguard social justice. The personnel of the task force have changed several times, but they have never given up the investigation of the case.
Twenty-eight years later, in 2020, the police in Peixian County, Xuzhou City, Jiangsu Province arrested a criminal and collected his DNA samples. By comparing the DNA in the database, it is found that the sample is highly similar to the biological sample information of the "medical record".
Nanjing police immediately went to Xuzhou to interrogate the criminal and investigate his activities. The criminal's criminal conditions directly ruled out the possibility of his crime that year.
The police focused on the criminal and investigated his family. After investigation 1 1 family, it was found that a man had been a soldier and settled in Nanjing. According to the age of the crime, his son is suspected of committing a crime.
Fall into the French open
The police locked the suspect's residence and arranged the arrest plan. In the early morning of February 23, 2020, the police arrested the suspect Ma Mogang at his home in Nanjing. After comparing the DNA samples, it was confirmed that it was consistent with the rape and murder case of Nanjing Medical University.
Ma Mogang seems to have predicted his fate long ago. After his arrest, he was very calm. He has been hiding in Tibet for 28 years and is a driver led by a state-owned enterprise. Colleagues and neighbors who live together day and night have a good reputation for him, but he turned out to be a murderer wanted by the police, which makes people afraid.
Never be manipulated by evil thoughts, let alone take chances. After years of old cases, the police rely on advanced investigation methods to investigate one by one. In the near future, more dead people can rest in peace, and criminals will eventually be punished.
