"Since it exists, the traces cannot be easily covered up. We will know if we investigate."

Tang Ze took out his cell phone, edited the information and sent it to Takagi and the other man. Then he thought about it and opened the ashtray in the car.

"Cigarette butt?" Naoki Kamii was surprised when he saw the cigarette butt in the ashtray. "Senior, why do I remember that Mr. Kanbayashi doesn't smoke?"

"I have the same impression. It could be that woman's fault, or it could be that Mr. Shenlin has learned to smoke. After all, people change."

It is not easy to develop good habits, but it is very easy to develop bad habits.

In his previous life, Tang Ze had met a colleague who had never smoked before he was fifty years old. However, because of the pressure of promotion, he learned to smoke.

However, Tang Zhe and his team are not specifically researching this, so there is no need to worry about it.

He simply put the cigarette butts in the ashtray into an evidence bag, intending to send it to Saito Hiroshi for testing later, intending to use scientific methods to explore the results.

Just as Karasawa and others were investigating Professor Kambayashi's accident car, Takagi and Sato Miwako also came to Professor Kambayashi's house.

Because the other party had lived here for a long time, it didn't take much effort for the two of them to get to know each other.

I heard from the neighbors that there has always been a young woman in the other family who comes to Professor Shenlin's house from time to time.

Of course, it wasn't the gossip about a lover that people criticized, but about a caregiver.

The man's wife fell seriously ill four years ago and was bedridden at home. The caregiver has been taking care of his wife since then.

After his wife passed away, although he no longer came frequently, he continued to take care of Professor Shenlin.

After all, an elderly person living alone will inevitably have some inconveniences in his life, so the other party has always helped on time.

Combining with Tang Ze's previous information, Takagi and the others hurriedly asked about each other's whereabouts, and then drove to the "Boai" nursing home.
