The world of American TV series: Starting with the L.A. Patrol

"So there's another question." Jack pointed to the corpses on the ground, "Where did the blood on them go?"

The total blood volume in an adult's body accounts for about 7%-8% of his body weight, which is about 5-6 liters.

Although the blood stains left by the two victims at the murder scene were obvious arterial splatters, they were far from sufficient in terms of quantity.

"The oblique religious sacrifices usually require the use of a large amount of blood, which is called a blood sacrifice. The posture of the first deceased has religious connotations, and the cigars and beer in the mouth of the second deceased can also be regarded as sacrifices."

Jack said and looked at Lopez, "Can you help investigate the local religious groups involved in black magic and witchcraft, and ask if there are any similar sacrifices.

The murderer may have used animal sacrifices at first. For example, Voodoo has a tradition of using cow heads, but living people and blood are usually advanced behaviors. "

Lopez nodded, "I don't know much about the situation in Tijuana, but I know who to go to. Give me one night and I should have the results tomorrow."

At this time, Jubal also thought of another clue, "Did Hannah find oil leaking tire marks at the scene?"

"Yes." Hannah's answer came from outside the video screen. "We arrived earlier this time, and the biodiesel has not completely evaporated. I have already taken samples and will send them back to the domestic laboratory later."

European countries that pay attention to so-called environmental protection and carbon emissions are the main consumers of biodiesel. Among South American countries, only Brazil, which is rich in soybeans, is promoting this expensive environmentally friendly fuel.

Of course, a large country in the East that uses kitchen waste oil, also known as gutter oil, to process biodiesel is an alternative.

The poverty-stricken population in Mexico accounts for more than 40% of the total population. The problem of food is obviously far greater than the problem of environmental protection. The murderer can afford the more expensive biodiesel, but he can't even repair the leaking fuel tank or oil pipe. This is a rather contradictory suspicion.

Using a flashlight, Jack followed the tire tracks around the body and found a puddle of oil more than twenty meters away. It seemed that the murderer had been using the same car from beginning to end.

Thinking about the war-damaged pickup trucks and cars running on the streets of Mexico, he sighed with regret.

If he is in China, he can ask the CSI laboratory to analyze the tire marks, maybe he can find out the vehicle model, and then combine the biodiesel clues to report to the local police. Even in big cities like Los Angeles or New York, it only takes two or three days. There can be results.

Unfortunately, we are in Mexico right now, and technical detection methods are almost impossible to rely on. But since the murderer may be a serial killer, BAU's behavioral analysis theory may come in handy.

By the time everyone returned to the hotel, it was already dark, Alice was still busy in front of the computer, and Aubrey was making coffee at the bar.

Jubal walked in and asked, "Is there any connection between the two victims?"

"Not yet." Alice took the coffee from Aubrey, brought it to her nose and smelled it, showed a satisfied smile, and then got down to business.

"The two had almost nothing in common except that they were both Americans. Lee Kern was an ordinary high school senior from San Diego and Robert Mueller came from a small town in Arizona.

He used to be an engineer for Mexico's BTL oil company, but left the job nine months ago.

But the strange thing is that although Miller's wife and two children live in Arizona, he has been traveling back and forth between the two countries for most of the year. "

"Looking for a job, or addicted to gambling?" Jack thought of the parking lot below the dog racing track where Robert Miller was killed.

Aubrey looked at Jack with a half-smile, "Probably not. Although Robert Miller lost his job, some of the stocks and businesses he had invested in had brought him good returns.

Gambling on greyhound racing seems to be his only interest, and the amount of each bet is not large. "

Feeling that this guy's expression was rather malicious, Jack asked curiously, "So?"

"So we traced some of his bills and discovered that some of them were not sent to his residence in the United States, but to Navado, a small town outside Tijuana."

Aubrey handed the tablet in his hand to Jack. On it was a photo of a family of three. The husband was still Robert Miller. The wife in her early twenties and the son who was only five or six years old had typical Latino looks.

"This guy has a family in the United States and a family in Mexico?" Jack was stunned, and then glared at this guy fiercely, finally understanding why he had a teasing expression on his face.

"Scum, a role model for all men, what a shame, unforgivable." Before someone could finish his thoughts, a car key flew towards him.

Jiejie took Hannah's arm with disdain and said, "Go and drive. Let's go visit this bigamist's wife in Mexico now."

"It's a very nice town. The surrounding environment doesn't look any worse than at home." Clay, who was called along by Jack, sat in the passenger seat and observed the situation outside the car.

"It's like the quiet countryside in the country." Jack nodded in agreement, "Since we left the city limits of Tijuana, we haven't heard gunshots and sirens for a while."

Hannah, who had been playing with her tablet in the back seat, showed her screen, "This is a wealthy area on the outskirts of Tijuana. It is said online that many wealthy Americans will buy properties here to support their lovers."

"What a wicked rich man." Someone chimed in casually, without any awareness of being worth billions.

The property here looks similar to that in the United States, a two-story building with a wooden structure, a small garden behind the front lawn, and the four people did not rush to knock on the door, but walked around the house cautiously.

"The surrounding area is safe, nothing unusual." Clay still carried a Noveske N4 assault rifle and a bulletproof vest with the FBI letters printed on it, and the other three people were also equipped with similar equipment.

Although Tijuana is not like Juarez, the entire city is like a battlefield at night, but they also passed through several tense and dangerous neighborhoods along the way.

And considering that they are about to face a hysterical Mexican housewife who is a major suspect of murder, it doesn't seem to be a very excessive move to come to the door with a long gun.

The four people stood on both sides of the door, Jack reached out and knocked on the door, and soon there was a sound of footsteps.

The young Latino woman and her young son appeared at the open door. The smile on her face disappeared instantly after seeing the four fully armed men, and turned into a terrified expression.
