"In the meantime, the media is focusing on the fact that the event did not comply with safety regulations.
Most of the 53 injured were injured in the panic.
When the bombs exploded, all 2,000 visitors jumped up and threw their chairs over at the same time.
In an instant, the entire hall was full of flying chairs over which event participants fell.
There were no more escape routes.
Event participants fell over the chaos, injuring each other, while the smoke spread and caused life-threatening injuries to the escapees' respiratory tract.
Now there is an investigation team that is determining who is responsible for the blatant disregard of safety regulations.
State anti-terror detectives and National Security Forces (NSG) are investigating the explosion site.
Kerala Chief Minister Pinarayi Vijayan said he was closely monitoring the situation.
The organizers did not have any trained stewards.
According to unconfirmed reports, Jehovah's Witnesses allegedly only used their own members as security personnel.
Why were there no local, trained security personnel on site?
There are trained security personnel who are regularly deployed at the congress site and know the locations.
But this would have cost money.
The congress hall is also not designed for full seating.
The hall is intended for catering events.
Weddings with a free dance floor.
It is unclear who provided the thousands of additional chairs that were shown in the posters.
Images from local television channels showed firefighters, ambulances and police officers being blocked from accessing the crime scene by a large number of people.
There were no security forces to keep the access routes clear and, for example, direct the victims to a collection point.
After the explosion, many people were seen inside and outside the convention center.
This hindered the evacuation and disturbed investigators.
The pictures show Jehovah's Witnesses re-entering the smoke-filled hall to get their cell phones or wallets.
You can see a brother picking up his cell phone from a puddle of water on the ground.
According to Kerala Industries Minister P. Rajeev, the explosion site was cordoned off by the police much too late.
Who is responsible for this chaos, which resulted in numerous unnecessary casualties among event participants?

The investigation files show that Dominic Martin bought the electronic components for the bombs in several stores under the pretext of making toys for children.
For example, he bought four remote controls and cables from electronics stores near Medical Trust Hospital at Pallimukku in Ernakulam.
To avoid arousing suspicion, he purchased the other components from various other stores.
That's why the bombs only went off one after the other.
They were toy car remote controls from various toy manufacturers.
He bought the gundu (high-impact crackers) from a shop in Tripunithura and filled petrol bottles at various petrol pumps.
A total of eight bottles, each containing one liter of petrol.
He then brought the material to his second home.
The neighbors thought he was renovating there.
Dominic drove to his second home in Athani near Nedumbassery on Friday morning after purchasing all the materials needed to make the bombs.
The police assume that he stayed in his apartment during the day on Friday and that Friday he finally assembled the bombs.
On Saturday he was briefly in the second home, but left after a short time.
On Sunday mornings he picked up the explosives in jute bags from his second home and brought them to the congress grounds.
It is unclear why he recorded his confession video in a hotel room.
After detonating the bombs, he returned to the second apartment and left the congress paraphernalia that he had with him for camouflage and the two toy remote controls used for the explosion there.
Only then did he drive to the hotel in Koratty and check in before posting a message in the hotel room on Facebook Live and then turning himself in at the Kodakara police station.
When he turned himself in at the police station, he had the receipts for the purchased materials with him.
During the on-site interrogation in the second home, Dominic Martin willingly assembled a bomb for the officers using the remaining components.
Judges and investigative authorities are shocked by the cold-bloodedness of Jehovah's Witnesses.
The documents he produced included invoices for gasoline purchases related to the production of the explosives.
The fact that he presented invoices for the purchased materials when posted at the police station strengthens the case against him, according to a senior police officer.
Martin is described as a person of "extraordinary intelligence and hard work."
His decision to give up a high-paying position abroad for such a shocking act leaves authorities perplexed.
Investigating officers described Martin as a "brilliant mind."
He left behind a lucrative job as a designer in the Gulf, which led many to doubt his motives.
In the meantime, he was in a Chief Judicial Magistrate Court for a "test identification parade", a procedural step in the legal process.
Again he refused any legal aid.
Although the court repeatedly offered him urgent legal representation, Martin insisted on representing himself.
He clearly stated that this was his decision and indicated that he had no financial difficulty affording his own lawyer.
Here's what he said at the Test Identification Parade:
Quote
"Since I had no other choice, I made this decision"
said Dominic Martin.
The investigation team is still trying to understand why Martin, who had a successful career abroad, carried out the attack.
As the case progresses, more information is expected to emerge.
