Things that solve crimes

Qin Henian thought deeply for a moment and said, "Except for serial murders, the causes of murders are nothing more than love killings, money killings and vendettas."

"In this case, the murderer had nothing to do with the deceased, so love killing can be ruled out. After the murder, the murderer committed suicide directly without touching any property. It was not a murder for money."

"So, there is only the last possibility, vendetta."

"Check to see if any of the murderer's relatives or friends had any accidents."

The three of them suddenly realized. Jiang Buyu immediately called the captain Cao Xuewu and explained the matter in one word.

Cao Xuewu slapped his head after hearing this, feeling annoyed as to why he had forgotten this. He asked Jiang Buyu to hand the phone to Qin Henian and said, "Hello, Medical Doctor Qin."

"Hello, Captain Cao"

After saying hello, Captain Cao said, "Sun Yue had a fiancé, Zhao Qi, who was kidnapped five years ago. The police caught the two kidnappers, and Zhao Qi was pronounced dead."

"Death? How did you die?" Qin Henian asked.

Cao Xuewu replied, "There was a fire and Zhao Qi didn't run out."

"Are you sure there are two kidnappers?"

"You suspect the third kidnapper."

"That's right, otherwise I wouldn't be able to think of the reason why Sun Yue killed someone."

"Looks like I have to make a trip to Jiangcheng."

The next day, Cao Xuewu invited Qin Henian to Jiangcheng, accompanied by a trio.

The five people arrived at the Jiangcheng Public Security Bureau. After being taken into the information room, Qin Henian couldn't wait to turn over the pages. The deputy captain on the side told them about the original case.

Five years ago, Zhao Qi did not return home until night after get off work. Zhao Qi's parents noticed something was wrong and prepared to call the police after searching everywhere but to no avail.

However, the call from the kidnappers came first, demanding a ransom of 100 million. Their son was kidnapped. Zhao Qi's parents decisively chose to call the police.

After receiving the call, the police immediately dispatched police and investigated everywhere. Finally, Zhao Qi was seen on the surveillance camera at a remote intersection being stopped by two men as he passed through an alley.

The two sides had a dispute, and then started fighting. Zhao Qi was taken away without hitting the two men.

The police were very angry and kidnapped people in broad daylight. The kidnappers did not take them seriously at all.

Following the surveillance, they found out the location of the kidnapper, an abandoned warehouse, and the police began to formulate a rescue plan.

However, what the police did not expect was that the warehouse caught fire, only two kidnappers ran out, and Zhao Qi died inside.

"The kidnapper's last confirmed crime, apart from the kidnapping case, why is there also a serial arson case?" Qin Henian asked, pointing to a line in the document.

The deputy captain explained, "There were three serial arson cases that year. After they were arrested, there were no more arson cases."

Qin Henian frowned, "Are there no witnesses or physical evidence?" The Jiangcheng police wouldn't be so casual.

"Yes, why not?" the vice-captain waved his hand, looking like there was no way it was possible.

"In the second arson case, a witness saw one of the kidnappers appear at the scene. The most important thing is that the two kidnappers admitted that they were responsible for the serial arson case."

"Even the warehouse was burned down by them."

Qin Henian's brows slowly relaxed and he asked again, "Are there only two kidnappers? Is there a third person?"

"The kidnappers only admitted that there were only two of them."

"What do the police think?"

The deputy captain grinned, "The police suspected that there was a third person, but there was no evidence. In the end, they could only transfer the two kidnappers to the prosecutor's office."

In fact, the police officers who handled the kidnapping case all believed that there was a third person, and they had been looking for it over the years, but there was no clue.
