In the early morning, the sun is faint.

At the mouth of Heliu Alley, several police cars were parked and blocked the alley.

The whole alley is tightly surrounded.

When He Yang and his party arrived, Forensic Doctor Zhang was already examining the body.

"Who called the police?" He Yang asked as he put on medical disposable gloves.

"Captain Hui, a sanitation worker."

"Su Ran, you go and ask the sanitation worker about the specific situation." He Yang raised his chin towards Su Ran.

"Roger!" With that, Su Ran walked towards the sanitation workers.

Su Ran is notoriously bold and careful, able to grasp details, sometimes she can interrogate things that others can't ask, and she can also pay attention to things that others don't pay attention to.

The uncle in the orange sanitation costume was in shock, sitting on the stone road and drinking water and patting his chest.

"Uncle." Su Ran politely called out to the sanitation uncle who was sitting on the ground.

When the uncle saw that it was a policeman, he quickly got up from the ground.

Su Ran gently pressed his shoulder, "It's okay, you just sit, I'll ask you a few questions." ”

"Oh, okay, okay, ask a few questions."

"Uncle, when did you find the body?"

"Oops, I was cleaning the street at four o'clock in the morning today, and I saw a big black bag next to the garbage can, so I opened it to see what kind of garbage was inside, and it turned out that when I opened it, it was a female corpse, it was too scary, I haven't encountered such a thing in so long life!"

It is estimated that this corpse will leave a shadow in the old man's heart for a long time.

On the other side, Forensic Doctor Zhang preliminarily examined the corpse, "Judging from the stiffness of the corpse, the time of death should be around ten to ten and a half past last night, the same mechanical asphyxiation, which also dug out the heart of the deceased, but this time it was not left-handed." ”

He Yang smacked his mouth, looking guilty and painful.

Another person died, and he felt more pressure than ever.

"I'll rub!" Fang Jinan, who was standing on the side, was relatively not so calm, and kicked the trash can next to him.

The murderer's crime is fast, and there is no time to follow, and there are few clues left, which is undoubtedly a psychological and time game for them who want to bring the criminals to justice.

Fang Jin'an's kick was not light, the black bag next to the trash can fell out, and at the same time, a cigarette butt fell out.

"Tweezers!" He Yang squatted on the ground, staring at the cigarette butt with his eyes dead and shouting.

The police quickly took the tweezers and the physical evidence bag, and He Yang picked up the cigarette butt, put it in the bag, and handed it to Forensic Doctor Zhang, "Extract saliva and test DNA." ”

There was silence in the police station, and Director Xu Zhangde Xu had a serious face.

"These two murder cases have an extremely bad impact! I was put under a lot of pressure from above, and we were given five days to solve these two cases! I hope you all cheer up! Race against the murderer! ”

The public opinion of these two cases made everyone in Ningjiang District panic, and the neighbors began to demonize the murderer, saying that the perpetrator was not a person at all, but a devil who ate hearts, and specially used this set of rhetoric to scare naughty children.

He Yang also knows that time is pressing, and if the murderer is not caught one day, someone will be in danger at any time.

The sky panics, the earth panics.

The heart-eating devil is on the street.

Don't get in the way,

Neither underworld nor heaven.

At midnight, the song reverberated on the empty streets, and it was particularly infiltrating.

A woman who had just finished her night shift heard this oozing song from a distance.

Thinking of the heart-eating devil incident that has been in a uproar in the past two days, she couldn't help but shiver and stepped up her steps.

As he was turning a corner, he bumped into a dark shadow head-on.

Wearing a large black hooded cape, the scalpel in his hand reflected a cold cold light in the moonlight.

She was stunned, her heart tightened suddenly, her pupils dilated suddenly, and before she could shout, she was covered with her mouth and nose.

The woman struggled desperately, biting the thin layer of medical rubber gloves on the murderer's hand.

The shadow raised the scalpel and stabbed the woman in the chest until she breathed, her teeth still clenching at her glove.

There was no way, the black shadow could only take off his gloves and hurriedly disappear into the thick night.

He Yang, who received the call to the police, was stunned.

It was less than 24 hours before the murderer committed the crime again.

At the scene of the crime, a woman collapsed in a pool of blood, and unlike the previous two cases, her heart was not lost, and she was holding a disposable glove in her mouth.

After receiving He Yang's notice, Forensic Doctor Zhang hurriedly came to the scene of the crime, "He died between twelve and one o'clock last night, he was stabbed in the heart, and died of excessive blood loss." ”

He Yang carefully took out the gloves in the deceased's mouth and handed them to Forensic Doctor Zhang, "This is estimated to be the murderer's, see if you can extract fingerprint information from the inside." ”

Fang Jinan asked around, and said that he didn't hear any screams in the early hours of last night, only a strange ballad.

Su Ran searched the neighborhood and found a bloody murder weapon in a flower bed not far away—a small round-headed scalpel.
