In 2016, a Summer Holiday turned to tragedy when m children were killed during a boating activity at a camp in russia. The news shocked the whole of russia. Three years on, a trial has found the summer camps director and her deputy guilty of leaving children in danger. They were sentenced to 9. 5 years in prison, while the case against the officials who are responsible for organising the trip is yet to come to court. It was widely reported that it was a sudden storm which was to blame for the tragedy. The bbc has seen evidence which suggests that there were systematic failures on the part of the authorities, who had been told about overcrowding, poor conditions and weak safety procedures at the camp many times. On 19june 2016, the lives of these families were divided into before and after. When zhenya romanov lost his parents at the age of three, valentinas family adopted him. They loved him as one of their own. Moscow is russias richest region. Every year, the City Government spends around 60 million sending orphans and children from low income families on a Summer Holiday. It is roughly the same amount as the annual budget of a medium sized russian city. Annually, around 60,000 moscow children go to holiday camps for free. Valentinas son, zhenya, was one of the children sent to the syamozero summer camp in karelia in 2016. The region borders finland, and is famous for its beautiful lakes and rainforests. Pine forests. Masha makarova was 12, and a professional swimmer. The children who survived said that when their boat overturned, masha was helping people to reach the shore. The water was only 12 celsius, and masha died of hypothermia. After the tragedy, several criminal investigations were launched. The victims parents didnt see much progress. They asked lawyer dmitry lapin to help them. He carried out his own investigation. As a result of these findings, six people ended up on trial. The director of the camp and her deputy, the head and deputy of the regions consumer watchdog, and two of the camps instructors. The court found the camps director, yelena reshetova, and her deputy, Vadim Vinogradov, guilty. They were sentenced to 9. 5 years in prison. Two officials from russias consumer watchdog were acquitted. A separate criminal case was launched against two employees of moscows department of social protection. Tatyana barsukova and yelena semkina have been accused of negligence. They were responsible for organising holidays for children, but the judge has sent the case back to the Prosecutors Office for further investigation. There has been little progress. We are catching the same night train the children would have taken from moscow to syamozero. We have carried out our own investigation to try and understand what caused the deaths of these children. We have been given documents which shed light on the events preceding this tragedy. Could these deaths have been avoided . Andrei 0rekhanov is the head of essoyla village near the camp. He first received complaints about it in 2010, when the camp illegally fenced off the public beach. Year after year, andrei found serious violations. Three years on, as the winter snow starts to melt, the camp is still closed. Andrei used to come here annually to carry out checks. He found new problems every time from leaky tents to overcrowding. Despite these discoveries, more senior government bodies allowed the camp to keep working. Syamozero camp kept winning government contracts. According to public databases, moscows department of social protection had contracts with syamozero camp for three years in a row in total, worth 1. 5 million. In 2016, they bought 923 places for around 600 each. But on the camps website, they were available for 100 less. After the tragedy, russias Anti Monopoly Agency accused department of social protection employees of conspiring with the Camps Administration to win the tender. It was not only local officials who made complaints about syamozero camp. This stack of letters was written by a mother whose daughter visited the camp in 2015. She wrote to local police, moscows department of social protection and other government bodies. She later became a witness for the prosecution. Here is what she wrote. I would like to complain about conditions in syamozero camp. There were twice as many children as should have been. They had to stay in leaky tents. Moreover, my daughter and two other girls refused to go on a boat trip around the lake in shabby boats with no roof. They were supposed to row for 32 kilometres in the rain. The three underaged girls were just left behind on the pier by the staff. They would not take them back to the camp. This complaint was written almost a year before the tragedy. Moscows department of social protection responded, saying that they did not find any problems during their checks. The local Prosecutors Office and the Health Ministry carried out their own checks and found multiple failings at the syamozero camp. They informed the department of social protection and its head about them. Despite all of this, the Department Still signed a contract with the camp for the equivalent of us 700,000 next summer. Immediately after the tragedy, the head of moscows social Services Department, vladimir petrosyan, said in several interviews the department had not received any complaints about the syamozero camp. The two employees of the social Services Department who were investigated for negligence, yelena semkina and tatya na ba rsukova, are both still employed there as social workers. The bbc asked moscows epartment of social services to comment on the documents found. They told us all of the questions you have raised have been subject to a criminal investigation which is still ongoing, and being handled by russias investigative committee. Until a judgement has been made, we cannot comment on this matter to the media. According to the evidence heard in court, some of the camps instructors and children received Text Messages from Emergency Services warning them about the impending storm. The children were afraid and asked if they could stay on the shore. The court heard that Vadim Vinogradov insisted that they go, and on 18june 2016, the group of 47 children and 3 adults set sail. Two out of three boats overturned. The alarm was only raised the next day, when 12 year old yulia korol managed to make it to a nearby village and tell them what had happened. At the same time, locals discovered the bodies of the first victims here on the beach. Yelena reshetova lost contact with part of the group, but as the court heard, did not alert the Emergency Services. Despite the storm, some of the local men went out to the lake and rescued surviving children who were scattered around the islands. They brought them here and tried to warm them up in this sauna. Five children who died at the lake were buried together at this cemetery in moscow. Their parents say that they find it comforting to think that their children are not alone. The body of valentinas son was found last, on the eighth day of the rescue operation. They had to do dna tests to identify him. It has been three years. Valentina and her family still cant talk about zhenya without tears. This tragedy has affected so many families. Valentina put the court case first, and as a result, lost herjob. She is now focused on trying to get justice for her son. Annas family fell apart after the tragedy. Her son now lives with her ex husband, and she lives with her youngest daughter. The families of the victims and the prosecution have won an appeal against the acquittals of the two officials from russias consumer watchdog, and the case will go back to court. The officials continue to deny any wrongdoing.
