Luke called to notify the forensic and technical teams to rush to the scene.

Later, he returned to Apartment 611, the scene of the crime.

The two scenes, the two deceased persons, and the murder weapons were also different, but the police found the second scene by tracking the gunman, indicating that the two cases were related to a certain extent, and the two deceased persons were probably killed by the same murderer.

At present, Luke is still unable to determine the murderer's motive.

"Raymond, what do you think of this case?"

Raymond looked out the window, "It's at least four to five hundred meters from here to the scene of the car accident. It's difficult to hit a high-speed moving target at such a long distance.

I guessed that the other party might be a professional killer, but there is one detail that makes me a little suspicious."

"What details?"

"Bullet casings.

If they are well-trained professional killers, they will take away the bullet casings after performing their tasks, but this gunman left the bullet casings at the shooting scene, which is very unprofessional."

Luke also walked to the window to check the scene of the car accident. If he was the gunman, there was a high probability that he would not be able to hit the target.

The person who can hit the target at such a distance is probably a professional killer. Even if he is not a professional killer, he has received professional military training.

Just like what Raymond said, if you have been professionally trained, you would probably have taken away the bullet casings. Why didn’t the gunman do this?

Luke turned his head and looked at the corpse aside, probably having an inference in his mind.

"Raymon, if you were the shooter, what would you do?"

Raymond replied, "Shoot, pack your equipment, collect bullet casings, clean up traces, and leave the scene."

Luke said, "What would you do if someone suddenly broke into the room while you were packing your firearm after you fired?"

Raymond said, "Kill the opponent."

"If there is not one person but two people who break in, after you kill the first person, the second person screams and runs away.

what will you do?"

"I'll try to hunt them down."

"What if you don't catch the other person?"

Raymond thought for a while, "In order to prevent the other party from calling the police or attracting more people, I will flee the scene as soon as possible."

"Yes, the reason why the gunman did not pick up the bullet casing was probably because he was disturbed by the intruder.

There is no perfect case in this world. No matter how rigorous the planning is in advance, unexpected situations may occur when the crime is actually committed."

Luke also leans towards the gunman being a professional killer.

It's important to determine this.

If it is a professional killer, then it is most likely a hired killing, and the investigation method and inquiry content will be different from ordinary homicide cases.

For example, alibi.

If it is an ordinary homicide case and the murderer kills the person himself, if the suspect has alibi, the possibility of the other party committing the crime can be ruled out.

But murder for hire is different. He only has to pay the money and does not need to kill the person himself.

"Dong dong."

Jenny knocked on the apartment door and said, "Captain, no blood was found, and no female suspected of being a witness was found."

"Good news, that means the witness is still alive." After Luke finished speaking, another doubt arose in his mind. If the witness escaped, why didn't she call the police?

"Jenny, have you found any other abnormal signs?"

Jenny thought for a while and asked, "For example?"

Luke said, "If you were a witness, what would you do after you escaped successfully?"

“Call the police.” Jenny blurted out and frowned, “But we did not receive any alarm information from this apartment, which means that the witness did not call the police, or in other words, she does not have the ability to call the police now.

Either dead, injured, or possibly held hostage by gunmen!"

Jenny suddenly thought of the quarreling couple in Apartment 707, "Captain, do you remember the injured woman in 707?

She had bruises on her face and was panicked.

Before, I always thought she had been subjected to domestic violence, and her reaction was somewhat different from domestic violence.

Could she be the female witness, and the man in the house was not her husband, but the murderer who held her hostage?"

Luke thought for a moment, "She was already standing at the door and knew we were the police. Why didn't she call the police?"

Jenny guessed, “Would the gunman be threatening her from behind and shoot her if she dared to call the police?

She had just experienced the 611 apartment shooting incident and was probably frightened, which is consistent with her panic expression."

Raymond said, "Your idea is very bold, but if I were the gunman, I would kill the woman directly without giving her a chance to contact the police."

Jenny said, "Is it possible that the gunman is also injured and needs this woman to help him cover?"

Raymond said, "This reason is not sufficient, the gunman will still kill people."

Luke looked at the dead man on the ground, "There is another possibility. The dead man was not an intruder, but a gunman."

After two intruders entered the room, one of the intruders exchanged gunfire with the gunman. The female intruder was frightened and ran away screaming.

Afterwards, the male intruder killed the gunman, processed the scene, and found the female intruder.

Because the two knew each other, the female intruder did not call the police, but the two also had a dispute over the incident, and the male intruder beat the female intruder."

Luke's speculation completely overturned everyone's previous guesses.

Raymond was a little confused, "Captain, do you have any evidence?"

"No, this is just speculation." Luke shook his head slightly, maybe it was the sequelae of being a detective.

Jenny said, "I agree with the captain's speculation, this is very possible.

And even if the captain’s guess is wrong, the woman may have suffered domestic violence, and we need to investigate.”

Luke said, "Raymond, please contact the company's real estate agency and investigate the situation of apartments 611 and 707.

Jenny, come with me to the 7th floor of the apartment to set up control."

"yes, sir."

…

The seventh floor of Pattu Apartment.

Luke climbed up the stairs. He carefully checked each step and found nothing suspicious.

Arriving on the seventh floor, Jenny looked at the door of apartment 707 and asked the two patrol policemen watching, "Is there anything unusual?"

A black patrolman said, "No one came out."

Jenny asked, "Captain, what should we do?"

Luke didn't answer, he was waiting for news from Raymond.

Jenny looked at her watch, "How about I call the door and bring that woman out."

Luke objected, "No, if the gunman inside the 707 is really a gunman, they might not suspect it if they call the door for the first time.

The second time he calls the door, he will definitely be alert, and you will be in danger by then."

Jenny said, "But the longer time passes, the more dangerous that woman will be. I'm worried..."

Luke interrupted the other party, "Calm down, it was just our speculation before. There is no evidence that the people in Apartment 707 are related to the shooting. We will wait until Raymond has verified it clearly before taking any action."

"Creak..."

After Luke finished speaking, the door of Apartment 707 opened without warning.

All the police officers present looked nervous.

A tall white man walked out of the room.

Jenny held a gun in both hands and shouted, "Los Angeles Police, don't move!"

"Put your hands up!"

Other police officers were also on guard with guns drawn.

The white man was startled and quickly raised his hands, "Hey, don't shoot, I don't have a weapon."

A patrol officer ordered, "Place your hands on the wall, slow down, and don't make any unnecessary movements."

A patrol officer walked over and searched the white man, "He has no weapons."

The white man said, "Sir, I am a good person and I have not done anything illegal."

Jenny asked, "What's your name?"

"Rudeg Yarolim."

"Where was the lady just now?"

"She's still in the room."
