Chapter 1120 Biodiesel Graffiti and the Hangman Gang

"Okay, now we know the murderer has his own car, but it doesn't help to find him. I didn't see any surveillance cameras along the way. I even doubt that even if we get the license plate number, it would be difficult to find the murderer."

Aubrey scratched the back of his head and showed a bitter face. Even when he was in Africa, he didn't feel that handling cases was as difficult as it is now. Although the Tanzanian police were not very capable, they were quite cooperative.

And at that time, there were enthusiastic local people (old Muto and his militia) escorting them all the way. Even if they were dealing with small local armed forces, there was no need to worry about any danger.

In Mexico, it was completely different. Even the police who were supposed to bring a sense of security to the people could not protect themselves. They had to cover their faces when they were in uniform.

If this case was really related to a large-scale drug trafficking group, it would not be something that their wanted criminal team could handle.

Even out of consideration for the safety of the team members, Jubal would apply to evacuate Mexico as soon as possible.

In fact, even Jack was reluctant to confront the Mexican drug cartels in an official capacity. Not only were there too many obstacles in the middle, but it was also time-consuming and laborious.

To plan an operation against a large-scale drug cartel, it might take months or even years to gather intelligence in the early preparations. Sometimes, agents had to be sent to conduct undercover work for years.

"Don't think too much about it. The current clues do not directly lead to the murderer being a member of the drug cartel, and the several large drug cartel active in Tijuana are maintaining superficial peace and there is no sign of war."

Jubal tried to boost morale, but it didn't work. After all, the team has maintained a 100% crime-solving rate since its establishment. Although everyone didn't deliberately publicize it, they were all proud of it in private.

If it really came back empty-handed because of the involvement of a large drug cartel, everyone could understand it, but it would be very unpleasant and embarrassing.

"Did you find anything?" Jack recalled his thoughts and found that Clay had been squatting in front of the two tire tracks, observing something carefully, and occasionally picking up a handful of sand and sniffing it.

Clay looked solemn, "This car is leaking oil. Although it has almost evaporated, I can still smell some smell, but I'm not sure whether it is gasoline, diesel or engine oil."

Hannah immediately became interested, squatted beside him, and also picked up a handful of sand and sniffed it carefully.

Just when Jack was wondering if she was going to lick it with her tongue, the girl showed a smug smile on her face and said with certainty, "This is biodiesel."

"You can smell it?" Jack grabbed her wrist suspiciously and sniffed her fingertips. There was indeed a little diesel smell, but it was smelly and sour.

Biodiesel is a fuel made from the alcoholization of discarded animal and plant oils, which is commonly known as the recycling and reuse of waste oil.

This is a green energy that is highly praised by environmental protection organizations. Of course, anything related to the word environmental protection usually means a high price.

"This is Mexico. Who would use this biodiesel as fuel for their car?" Aubrey felt a little incredible.

"Extreme environmental protection organization? Maybe the murderer is also an American." Hanna guessed.

People who work hard for a living all day will not care about environmental issues. Only rich people who can take a private jet to eat a cake will worry about it.

"OK, another clue. I'll ask Alice to check if there are any extreme environmental protection organizations in Tijuana in California."

Before Jubal finished speaking, he saw Lopez and Jiejie walking through the alley, so he asked, "Did you get anything from the bar owner?"

Jiejie sighed, "We asked the owner, bartender and waitress, but there were too many tourists last night, and many of them were teenagers of the same age as Li and Rosie.

In addition to a lot of complaints and grumbling, we didn't get anything."

"I seem to have seen this mark somewhere." Lopez looked at the blood-spattered earth wall for a long time, and pointed his finger at a black graffiti like a stick figure.

The earthen wall was covered with similar graffiti, but the one he pointed at looked relatively new, probably drawn with charcoal.

Everyone looked in the direction of his finger for a long time, and after a long while Aubrey asked hesitantly, "Is this a gallows?"

Lopez nodded repeatedly, "Yes, that's right, this is the symbol of the Hanged Gang, this logo shows that this is their territory, that's a gang of lawless bastards."

"Do they also sell drugs? Could the bag of cocaine that Li took away in the bathroom be related to this Hanged Gang?" Aubrey asked hurriedly.

"All the gangs here are more or less related to drugs." Lopez always wore a mask. Although he has become a CBP agent now, he often has to travel between San Diego and Tijuana and appear at various crime scenes related to drug cartels.

Although everyone can't see his expression, they can still hear a hint of helplessness in his tone.

"The Hangman Gang? They don't sound like the kind of people who would kill people with sickles, but maybe they're a bunch of Harley riders who believe in environmental protection." Aubrey's expression suddenly relaxed, and he regained his usual optimistic attitude.

Among the several drug cartels active in Tijuana, there is no gang with such a country name, which means that if the murderer is really a member of the Hanging Gang, he is the type that the Most Wanted Criminal Team can deal with.

As expected, according to Lopez's introduction, the Hangman Gang is just a motorcycle gang with a membership of about 20 people. The boss and main backbone are Latino Americans.

Although they also do some drug smuggling, they mainly sell some bulk goods while satisfying their own needs, which is comparable to that small package of low-quality cocaine with low purity.

There is no better suspect at the moment, but since the case happened on the territory of the Hanging Gang, it is only right to inquire about it from local gangsters.

Even if they didn't do it, it's a good way to find out if any suspicious people have been around recently and to learn about local "news".

"They mainly operate near Aquila Beach, but now is not the time. The guys will not gather together to start their party until after 10 p.m."

Lopez made an invitation gesture as he said, "There's still some time until dark. Before that, how about I take you to the best restaurant in the city for a meal?"
