Trace Laboratory?"

In the office area, Michelle said the news, and Lacey next to her immediately came up and asked:

"Ann, what are you looking for them for?"

"Ask them for help, of course."

Luo An replied casually, walked to the side and picked up his coat and put it on his body, looked at the puzzled eyes of the detectives, and explained with a smile:

"Remember the first serial murder case against street workers?"

"Of course!"

The agents nodded in unison, and Cheniele said:

"I can't find any clues on my mobile phone, and it's impossible to go to the streets and ask about those workers, so our investigation has been stuck."

When Chenille said this, Mona's eyes lit up and she asked:

"Ann, did you think of any clues?"

"I can't think of a clue."

The conversation wasn't long, and Roan wanted Dr. Covard to change the order of the autopsies, leaving the autopsies of the second serial homicide case with a gunshot in the back of the head at the back, and dealing with the bodies of the victims in the first case of serial homicide first.

Thirdly, the economy is in good shape and there is a second means of transport.

"Ladies and gentlemen, in the first serial murder case, there were 12 corpses of women engaged in physical work.

Except for the first five victims, who have been dead for too long and have turned to white bones, there are not many things left, and the remaining seven victims, although their bodies are badly decomposed, still have a lot of things left."

"That's right."

While Mona and Chenelle gave him a thumbs up, Lacey, Winslow, and Michelle said that they would also go to the trace laboratory with Ann.

Luo An shook his head and explained:

"But my thoughts are the same as the second serial murder.

Since we can't find any useful clues from the experiences of the 12 victims, we might as well turn our attention to the murderers themselves."

Lacey's brows furrowed, and she snapped her fingers and said:

"First, a white male, about 4,055 years old.

"No, that's not what Roan said."

"But the murderer himself, we have already found someone to do a profile."

Previously, in the conference room, several paths to the investigation of the first serial murder case were blocked, and when the detectives were at a loss, Luo An set his sights on the victim's body.

Luo An handed Mona a "you know me" look, coughed lightly, and explained solemnly:

Second, they are married or have a girlfriend and are highly educated.

These profiles can help us verify or eliminate suspects during the investigation, but now our investigation is stuck and we can't find any suspects at all."

"We'll go with you."

Fourth, there is a repressed mental or emotional situation......

For the sake of Luo An's face and the specialty coffee beans in his hand, Forensic Doctor Covard agreed without much hesitation.

Chenelle's eyes moved slightly, and Mona quickly remembered something, shook her head at Lacey, then looked at Juan, and asked:

"Do you think that the bodies of those victims may have information left by the murderer?"

Later, Mona and Michelle discovered the post on the Underworld website, and before everyone went to New Jersey to arrest Innis Heller, Roan took the time to go to the trace laboratory and had a brief chat with Dr. Covard.

However, Roan refused everyone's request to go with him, after all, the work at hand was not finished yet, so he only took Lacey and Cheniele into the elevator.

"Good evening, Mr. Covard."

"Good evening, Team Leader Roan."

Luo An and Dr. Covard shook hands and exchanged a few simple pleasantries, and the two quickly turned their words to the point.

Dr. Corade took the three of Roan into the evidence office, took out three packets of transparent evidence bags from a large cardboard box, and said:

"These are us

Clues found on the bodies of the victims of the physical workers."

Chenelle took the transparent evidence bag and found that there were a few tiny hairs inside, and Lacey next to her was immediately refreshed when she saw this scene, and hurriedly asked:

"Mr. Covard, are these the murderer's hairs?"

"I'm not sure, but most likely not."

Dr. Covard shook his head and waved his hand to a white man in a white coat with black-rimmed eyes on the bridge of his nose, who looked to be about thirty years old, and introduced:

"This is my student, Agent Xavier in charge of DNA testing and other things in the Trace Laboratory, you can just ask him about these things."

After the introduction, Doctor Corvad still had something to do and left first, and Luo Ann reached out and shook hands with the Xavier agent and asked:

"What's the matter with these hairs?"

"They were found on the corpses."

Agent Javier lifted his glasses on the bridge of his nose and explained with a smile:

"The bodies of the victims of the plastic workers were not detected with human white genetic material, only the dimethicone used in contraception*.

There were no other people's skin scraps or flesh in their fingernails, and we only found a few hairs that didn't belong to them in the four victims who died in the shortest time since now."

Luo An nodded, and then asked:

"Have you had a DNA test?"

"It's already been done."

Agent Javier nodded, seeing the expectant eyes of Lacey and Chenelle, he showed a helpless smile, took out a few test reports from behind him and handed them to the three of Roan, and said:

"We found a total of 9 hairs, 3 of which came from a woman.

We found out that she was an elderly woman who worked in a community centre, who was closely related to the deceased and had passed away from this world with liver cancer five months ago."

Looking at the report in his hand, Roan's expression remained unchanged, Chenelle's brows were tightly locked, Lacey was silent for a few seconds, then looked up and asked:

"What about the six hairs on the back?"

"The remaining six hairs belong to both sides, but none of them are human."

Agent Javier spread his hands and said:

"Two of the hairs came from dogs, and our internal database has never recorded the DNA of dogs, so we couldn't find it at all.

The other four hairs are not real hairs at all, they are all wigs on the head of a doll."

After Agent Xavier's introduction, Lacey was slightly stunned, and said in a few seconds:

"That's a ...... A surprising discovery."

"Indeed, I didn't expect that either."

Agent Javier looked at Racy's face, smiled and nodded, Luo An put down the document in his hand and asked:

"Anything else?"
