The Strange Drowning in Shuitian Town

Three bizarre murders occurred in Shuitian Town in a row, and the deceased were all drowned. The police officer in charge of handling the case, Lao Mao, discovered that the three murders were all homicides, and they were all related to a "shipwreck" ten years ago. The dead were all people who survived the ferry from Shuitian Town to the city. Ten years ago, three people drowned in that incident. In addition to Lao Mao's wife, there was also a middle-aged man and his five-year-old child. Lao Mao deduced that the murderer of the three murders was probably the middle-aged man's wife Ye Qian, who was seeking revenge for her husband and son. Lao Mao went to investigate Ye Qian and found that Ye Qian committed suicide several times after the "shipwreck incident" and became insane. She lived in a mental hospital for five years and then disappeared mysteriously. Continuing to investigate the case, Lao Mao discovered that a woman named Song Xianzhen in the town was probably Ye Qian, and immediately launched a comprehensive investigation into her. After many twists and turns, she finally exposed Song Xianzhen's false identity and confirmed that Song Xianzhen was Ye Qian, but she still could not be arrested and brought to justice - there was no evidence that the three murders in the town were related to Song Xianzhen, also known as Ye Qian. Seeing the murderer at large, Lao Mao couldn't bear it and continued to fight with Ye Qian with all his strength to catch Ye Qian and bring him to justice. In addition to cleverly dealing with the police to protect herself, Ye Qian also carefully planned the last step of revenge, killing Lao Mao - Lao Mao was present at the "shipwreck incident" that year. Ye Qian believed that Lao Mao had an unshirkable responsibility for the death of her husband and son. The sky net is vast, sparse but not leaking. After a thrilling battle of wits and courage with Ye Qian, Lao Mao finally found evidence, arrested Ye Qian, and solved the case.
