Autopsy room.

Emma pulled off the cover, the poor body so charred that it wasn't clear whether it was a woman or a man. The bones were almost visible with blackened flesh like overcooked steak. A preliminary check showed it was female.

Her whole body was blackened, some bones were even visible between the flesh that had almost turned to charcoal. Her eyes widened as if they were about to fall from the socket. The eyelids were burnt out, the poor eye screamed as if it witnessed the second her life ripped from her body.

Her hands were still in the initial position, both in a tied position over her head. That's what Emma and other coroners were trying to fix at least to make its position back to normal before the follow-up autopsy was carried out.

Smoke was still slightly rising from between the bones as if it was overcooked meat.

Sam entered with Dakota.

Emma approached with her note sheet with the data she had collected.

"This is the report result about the body from Rina before she goes out. A woman, twenty-eight years old, single, works as a tax consultant in a well-known company. Last night she just celebrated her anniversary after working for five years at the company. Her friends said the last time they saw her was around eleven o'clock past thirty from the karaoke club, they went home and nothing strange happened after that. The victim's boyfriend contacted her before midnight asking if she wanted to be picked up or not, and when he picked her up at the specified location, he couldn't find her anywhere."

Sam frowned, besides as an experienced painstaking coroner, Emma now becomes Rina's assistant since that little girl doesn't like to stand too long beside the ugly corpse.

He takes over the sheet from the young lady's hand.

"Hmmh, so it happened around midnight until dawn"

Emma nodded.

"Yup, seeing from the very warm body, the perpetrator deliberately made the victim's body burn longer until it extinguished itself"

Sam lowered his head to smell the smoke that was still coming out a little.

"What's that smell? It smells very strong"

Emma nodded again.

"Yeah it's thinner"

Sam frowned.

"It's weird, using thinner, why don't you just use gasoline as well?"

"It's flammable, the first thought might have been the trigger" Emma answered.

Dakota moved around the body and observed what he visible on it. From the size, the victim has quite a large figure, which means needs lots of effort just to hang her in a very high position. The culprit must be more than one or two, or maybe more than that.

He stop his step when saw some smoke still hovering near the burned feet, he came closer to check on it.

Dakota who was standing next to Sam suddenly gripped Sam's arm tightly, he seemed to be struggling to catch his breath.

"Sam"

"Eh Dax, what's wrong?"

Dakota moved away from the corpse. He accidentally inhaled some of the smoke that was still sneaking out from the body. Sam helped him sit up while Emma rushed to get him a drink.

"What happened? You look so pale all of sudden" Sam asked worriedly. Could Dakota be afraid to see the corpse? Although he had often encountered murder victims who were far more sadistic and strange than this before.

Dakota tried to collect his breath, his chest tight.

"Cough cough"

Sam glanced at the smoke coming from between the corpse's thighbones.

"Have you checked what chemicals are in this body? Dakota has an extraordinary allergic reaction to some chemicals such as sulfur powders or liquids, maybe you should check it"

The smoke that was emitted did still contain chemicals, however, they didn't expect this reaction which is very dangerous for Dakota.

"I'll take the sample to the lab" Emma replied.

....

...

Not long after that.

Sam and Ron were already sitting in their office, while Dakota was sitting at one of the empty tables where he had been for a few months. Unlike others which were full of files, his tables are squeaky clean and shining.

Rina, Sam's junior colleague approached after getting the lab results for the victim. They named the case 'Tower Crane Flames' as their way of distinguishing one case from another.

As soon as Sam took it the girl immediately sat in front of Dakota, she was also one of the fans, and it was impossible to miss the time to see him at that time.

"Hi prof"

But Sam's hand pinched her ear.

"Eits what are you doing, quickly explain what this means"

"Ouch it hurts Boss"

Rina groaned in pain and finally followed Sam back to the whiteboard where the wall of Fames was displayed.

Sam crossed his arms in front of his chest, looking at Rina with a sharp gaze.

"Then, what are you waiting for?"

Rina grabbed the paper, still groaning in annoyance, but seeing Dakota was also waiting for information from her made her excited.

"So, from the lab results, it seems that the perpetrator used several different chemical liquids. The color of the burn marks was different in several places. The perpetrator started the fire from her feet, using thinner as the base, and the fire spread throughout the body with other oils and kerosene. The upper body contains a lot of kerosene, and the lab also found a small amount of sulfur powder on the legs. Before her death the victim had burns on the soles of her feet, it was suspected that the coroner saw the post-mortem condition"

Sam frowned and saw some photos on the whiteboard, photos of burn victims that might be possible to give a little hint.

"If thinner is a liquid that is commonly found in construction areas. It could be that the perpetrator got it on the spot, but hung it up and ignited a fire from her feet, that is too much. I mean, you see how the officers are having a lot of trouble lowering the victim's body while the culprit seemed to easily tie her there, it just so happened that the crane had stopped operating because the engine was broken. Then how could it hang there? But, why did they mix sulfur? It looks like the culprit just plays around which will be in vain because, in the end, they will kill her viciously"

Rina approached.

"It could be just for satisfaction. According to the report from the crane foreman it had stopped operating because some spare parts were damaged and they planned to fix it today. But the other crane was not broken"

"They use two cranes at once" said Dakota. Sam and Everyone else turned their heads, Dakota stood up from his spot and approached.
