Now it is basically determined that there are no clues from Lan Keer. Because she has no external injuries or bruises, even if she has it in her body. Essence. DNA materials such as liquid, soaked in water for nearly 20 days, have long been diluted by water to the point that they cannot be verified.

The Los Angeles police have also checked the call records of Lan Keer's mobile phone, most of them are talking to family members, and some others are classmates and friends, which have been ruled out.

Coleman and Nathan found themselves in the same frame of mind as they had when they first approached the case a few months ago – looking around in a daze. In fact, many of the things that Wang Lei analyzed in the past two days were also thought of and discussed at the beginning, except that they did not conclude that Lan Keer died of murder at first sight like Wang Lei.

Julie Mo sat aside, and she also wanted to know where Wang Lei would start. I can't just say that Lan Keer is not a suicide and it's over, there has to be a next step.

Wang Lei picked up a transcript report from the coffee table: "Isn't this transcript not attracting your attention?" This time, even Julie lifted herself to see that it was a questioning of a suspect by the Los Angeles police.

On February 19, the police found Lan Keer's body in the roof tank of the Cecil Hotel. Because the hotel confirmed that the roof access was locked and the other door was connected to the alarm system, it would be difficult to get to the roof unless it was a hotel employee.

At that time, the Los Angeles police deduced that Lan Keer should have died of murder, and the murderer should be someone familiar with the hotel environment, most likely the hotel staff and guests.

On February 23, after interviewing most of the employees of the Cecil Hotel, the police identified a Cecil hotel employee named Eric as a major suspect in the case.

In the eyes of the Los Angeles police officers, Eric theoretically has the possibility of entering and exiting Lan Kear's room at any time to commit a crime.

And, because he is also an internal staff member of the hotel, it will not be difficult for Eric to get the key to the roof of the hotel.

But after investigating Eric's alibi, police released Eric.

According to subsequent revelations in the media, Eric was not at the hotel at all that night, but returned to his home. Eric's whereabouts that night were witnessed not only by family members, but also by several people in the neighborhood.

Nathan shrugged: "Wang Lei, we know this, our FBI has also re-investigated Eric's whereabouts, this person is innocent, although he has the key." ”

"I have a habit." Wang Lei smiled: "I never preset any position for myself, even if there is a lot of information in front of me. I like to speak with evidence. ”

Julie also nodded and agreed with Wang Lei's opinion. As a qualified police officer, whether the deceased or the murderer is Chinese or American, everyone should not take a preconceived position.

In fact, Coleman and Nathan had already made this mistake, and they had already decided in their hearts that Eric was not guilty. But this time, since the investigation is restarted, all positions must be put aside.

Coleman and Nathan, who understood it, rethought Eric's question, and Coleman asked: "Even if Eric was investigated by the police at the time, there were some rumors on the Internet that he was not good, and he did not make a move. ”

Resignation can be expressed as anger and avoidance of rumors; It can also be expressed as fear, timidity towards what happens. Then, if you don't resign, it can also be understood that you are not stubborn to prevent the police from seeing the flaws, or that you have a clear conscience and are bright.

"Why don't we go and ask Eric about it?" Nathan tentatively made a suggestion.

"There's no rush yet." Wang Lei rejected this seemingly good idea. All things are foreseen, and those who are not prepared are wasted. According to Wang Lei's habit, without a certain degree of certainty and indestructible evidence, a blind attack foreshadows the end of self-inflicted humiliation.

Especially now in the United States, a place where the police and the FBI can be sued in court at any time, they are only a mere consultant, and it is estimated that there is still no official consultant.

There is another very important reason why Wang Lei disagrees and did not say it, the Los Angeles police and the FBI's investigation of Eric at the beginning would not be false, and he just felt that this person was suspicious, but it was only suspicious.

Wang Lei asked another question: "On the morning of February 19, the first British tourist who complained to the hotel about the low water pressure and the strange smell in the water, Sha Bona, did you not make a record of what you were doing?" ”

Coleman looked back for a long time and suddenly realized, "Oh, you mean Stephen, the English man in his 40s with messy hair, rosacea, and a big belly." Why do you want to ask him? He just complained to the hotel, if it weren't for him, we wouldn't have found Lan Keer's body! ”

Coleman slammed his mouth shut, and Nathan's eyes widened, "You, you, what do you mean?" ”

"Yes." Wang Lei rolled up a stack of files and knocked on the table: "That's what I meant, you think right." ”

Wang Lei suspects that this is a serial killer or a serial killer imitator. As for who he wants to imitate, it is still unknown.

Serial killers have one thing in common, they are lonely and proud at the same time. In their own eyes, murder is not a crime, but art or "love".

They usually kill strangers, so there is no clue to be found from the victim's social circle. They will choose a very hidden or unknown place to do it, and then, they will stay on the scene, watch the police clumsily busy, and get pleasure, accomplishment and high through the discussion and fear of the surrounding crowd. Tide.

"Actually, the Los Angeles police initially thought that the murderer was still in the hotel, and I thought it was right, but the direction behind them was wrong." Shrugging his shoulders, Wang Lei turned to Julie, who could listen attentively, and raised the empty coffee cup.

Julie, who has always regarded herself as calm and strong, blushed rarely, stood up and hurriedly ran out of the house to bring in a pot of coffee. She had already left Yang Qian and Wang Shui'er behind, and just wanted to hear Wang Lei continue to explain.

Coleman and Nathan looked at Wang Lei like children eager to get candy, and the cigarette in Coleman's hand had unconsciously left only the filter.

"So, I think, here's the thing......" Wang Lei lit a cigarette for himself, took a puff, and the smoke covered his little eyes full of longing.

Lan Keer left home for Los Angeles and stayed at the Cecil Hotel. The security environment around the hotel is relatively poor, perhaps, when Lan Keer went out to play, he was teased by some people.

This can be seen from Lan Kerr's Facebook, on January 27, Lan Koil posted on his Facebook that "I'm going to go out tonight, I hope those Italian and Mexican stalkers don't come close, I feel like they're taking me as a prey and want to capture." ”

When he said this, Wang Lei diverted the topic and explained to them a question that he had called several medical schools in Los Angeles a few days ago to consult, and it was also helpful for the three of them to understand the next story.

According to the report issued by the Los Angeles Prosecutor's Office and information obtained by the Burnaby Hospital where Lan Keer went to the hospital when he was in Canada, it was indicated that Lan Keer suffered from "bipolar disorder"

Bipolar disorder, also known as manic-depressive disorder, is characterized by the constant experience of two opposite extreme emotional states: mania and depression.

That is to say, in Lan Keer, mania and depression will often recur, and the intensity and duration of this emotion exceed the usual emotional ups and downs of ordinary people.

To be specific, that is, Lan Keer will appear in the first half hour of the mood of happiness, excitement, energy, talkative, sex. Desire. Insomnia – This is not insomnia in the usual sense, where sleep is shortened, but there is still a lot of energy, and there is a decrease in self-control and a sense of crisis.

In the second half hour, Lan Keer will feel melancholy, including sullenness, sadness, inability to do anything, grief, and self-loathing...... Wait a minute. If you enter into severe depression, you may also feel that you have lost the motivation to survive, give up on yourself, and have suicidal thoughts.

Moreover, according to Wang Lei's own information and the answers given by several medical research institutes, until now, bipolar disorder cannot be cured, and the intensity of emotional ups and downs can only be controlled through drug treatment.

"In fact, the best treatment for Lan Keer is to learn to face her own emotions that change too quickly and violently through conversation therapy with a psychologist." Wang Lei sighed.

Julie thoughtfully refilled Wang Lei with a cup of coffee: "It is her own choice to travel alone, and this is not your responsibility." If you can find her killer, I think she will pray for you in heaven. ”

The conversation was short and intense, so intense that Wang Lei had lit a third cigarette in a row. Taking advantage of this gap, both Coleman and Nathan, who were strongly stimulated, seized the time to smoke a cigarette to relieve the shock in their hearts.

These things included Lan Kerr's illness, and the FBI and Los Angeles police first learned that no one would have linked it to Lan Kerr's death at the time.

In addition to the report issued by the Los Angeles Forensic Laboratory that determined that Lan Keer died of suicide, the word bipolar disorder was borrowed, but it was only lightly mentioned and not elaborated.

"In this case, Lan Keer's bipolar disorder is extremely easy to be considered as a trigger for suicide, especially when there is no trace and evidence of the murderer, this reason is easier to borrow." Pressing the half of the cigarette in his hand in the ashtray, the corners of Wang Lei's mouth turned up slightly. Isn't it? The Los Angeles police did exactly that.

Yang Qian and Wang Shui'er happily jumped and jumped in the living room below, and Wang Shui'er's voice was the loudest: "Wang Lei, come down quickly, come and see what I bought?" ”

The four of them glanced at each other, Coleman and Nathan were extremely dissatisfied, the matter was at the most critical juncture, why did these two women come back from shopping, how good it would be to continue shopping! Julie laughed and ran downstairs.
