Ana Figueroa, 55, told Daily Mail Online that though she cries every night, those responsible for the explosion and handling its aftermath have not reached out to her.

Scroll down for video . Ana Figueroa (pictured with husband Nixon) has spoken out for the first time since her son Nicholas, 23, died in a gas explosion on New York City's Second Avenue . The young man and recent college graduate was paying the bill on a blind date at a sushi restaurant when three buildings in New York's East Village were destroyed . Her Upper East Side family, which includes Nicholas's father Nixon, 52, and his three younger brothers Brandon, Neal and Tyler, says it still 'wants justice' and those responsible for the explosion to be punished. However, nearly one month after the blast that killed Nicholas when he was on a blind date at a sushi bar, answers about what exactly happened in the explosion remain unclear. In early April, according to the New York Post, a plumber allegedly admitted to law enforcement that he created an illegal gas connection in the building. allegedly at the request of Michael Hyrnenko, the son of landlord Maria Hyrnenko. Mrs Figueroa said that she had not been contacted by Ms Hyrnenko and has only learned about her life after reading it in media reports. She has learned that Ms Hyrnenko is also 55 and also has four children and said Thusday, 'I wonder how she would feel if she were to lose her kid'. While he said that they didn't want to 'blame' anyone, Mr Figueroa said that the family 'wants someone to come forward and say that they did this'. Nicholas's mother, who has not previously spoken at length to the press, said she had contacted a lawyer about filing charges against the landlord, though she is waiting until after the results of the city's investigation. The Figueroas say that neither the landlord of the demolished buildings, Mayor Bill de Blasio nor Con Edison have contacted them with condolences following their loss . The family, who are afraid that their son's death and its cause will be 'put under the rug' have set up a memorial at the site of the explosion . Mrs Figueroa, who was hugged by passersby who saw the memorial to her son, said that she still cries every night . A wall has been placed around the site of the explosion, which destroyed buildings at the corner of Second Avenue and Seventh Street and damaged windows on one adjacent . Attempts by Daily Mail Online to contact Mrs Hyrnenko, who switched lawyers after the explosion, for comment were unsuccessful. Beyond Ms Hyrnenko, the Figueroa family said that other parties such as utility company Con Edison and the owner of Sushi Park, where Nicholas was eating when he died, bear some responsibility for his death. Mrs Figueroa faulted them for not stopping gas flow to the building and continuing to run a restaurant in a dangerous situation. 'Everybody has a part of this', Nixon Figueroa said Thursday. Now the Figueroas are left with their son and brother's death as the story fades from headlines, and the feeling that swiftly finding the person responsible is not a priority for authorities. 'They're going to say ''It's only two lives, it could have been more'', but it was my son', Mrs Figueroa said on Thursday as passersby hugged her in consolation. The explosion resulted in the deaths of Nicholas and Moises Locon, 26, a busboy at Sushi Park. Her family was last contacted by New York City authorities before the April 7 funeral for Nicholas, when help with services were offered. A GoFundMe page in memory of Nicholas met it's $30,000 goal, and the Figueroas did not take the city's help. Despite the relatively small number of victims, Mrs Figueroa said that she had not received a phone call from Mayor Bill de Blasio. 'We're nobody,' she said. 'Now I really need their help if we don't want this to be pushed under the rug'. A spokesman for the Mayor released a statement to Daily Mail Online saying: 'Following the East Village building collapse members of the administration were in regular communication with the families of the victims . 'Additionally, the Mayor's Fund to Advance New York City raised more than $150,000 for the victims of the tragedy and the administration's offer to assist with funeral arrangements was declined.' Nicholas Figueroa, (left) a former model, and Moises Locon, 26 (right), both died at Sushi Park restaurant . New York City officials offered to help pay for Nicholas's funeral in early April, though the family was able to pay for it with help from a GoFundMe page . Mrs Figueroa was in tears at the funeral as she held a red rose and wore a button remembering her oldest son . Though the memorial set up on Thursday is a sorrowful reminder of her family's loss, the mother says that her sadness has mixed with anger over fears that her son will have 'died in vain' and no one will be held responsible. Ms Figueroa referenced other New York City incidents such as a crane collapse in 2008 that killed two and a fire in 2010 where those judged responsible faced manslaughter charges. The owner of the crane company and three men connected to the 2010 fire were all acquitted. She knows that the odds of a criminal conviction are small, but hopes that those responsible will help establish a small park on the property in memory of her son, who loved nature and meditating. The grieving mother said that those responsible include Con Edison, the utilities giant that said part of the building's gas works failed inspection about an hour before the explosion. She has also yet to be contacted by officials from the company. Con Ed released a statement to Daily Mail Online saying: 'We said on the day of the explosion and since then, that our thoughts and prayers are with the victims of this tragedy, and we made a significant contribution to the Mayor's Fund to help those affected.' Ms Hyrnenko's building had previously failed a Con Ed inspection in August, when workers discovered that a pipe had been tapped in a dangerous way, the company told the New York Times. Mrs Figueroa said that illegal gas tapping should not be a 'three strike' policy and that gas to the building should have been shut off completely following the second failed inspection. A Con Edison spokesman told Daily Mail Online that the March 26 inspection was on 'work the building owner was doing in connection with the installation of a new service'. The spokesman said 'The work did not pass the inspection and our inspectors left. The new service was locked, meaning that gas could not be accessed by it.' A plumber allegedly admitted to law enforcement earlier this month that he had created an illegal gas connection at the site of the explosion . Smoke from the fire was visible from around New York City as firefighters worked to combat the blaze on March 26 . The investigation into the incident by police and fire authorities is ongoing, with much of the suspicion falling on the buildings' gasworks . Con Edison has previously said that it was replacing a small pipe with a larger one that would allow both the building residents and the sushi restaurant to receive gas. Restaurant owner Hyeonil Kim told the New York Times he believed that the residents had been getting gas since the summer from a pipe coming from Ms Hyrnenko's other building next door. Gas is thought to have still been flowing through the old piping after the inspectors left. After the inspectors left, Ms Hrynenko's son Michael was down in the basement investigating a gas leak during the explosion. He was carried out by a general contractor with him. 'Our understanding is that the criminal investigation continues,' the company said in a statement. For now the mother is left with only pictures and messages from her son. Her last texts from Nicholas, with whom she would talk about 'everything' including  include message where he asks her to cook his favorite chicken for dinner. The young man had just gotten his bachelor's from Buffalo State College and had been home for three months before he died. Right before meeting his blind date at Sushi Park, Nicholas, a former model, had texted that he was about to have an 'interesting experience'. Ms Figueroa did not hear from her son again, and was knew that he was in the blast when she saw that his debit card had been used at the restaurant right before the explosion. After spending a long night at a nearby school hoping that her son would be found in the wreckage, Mrs Figueroa was later shown the place where he died. While the family may worry that officials will forget about their son's death, she is grateful for public support. Visitors to the Second Avenue memorial can now read testaments to the loving brother and son and see the spot where the explosion took his life, which the family has marked with white roses. The family was shown the spot where their son died and planted white roses in memory of the 23-year-old . The recent Buffalo State College graduate had texted his mother saying that he was going on an 'interesting experience' before his blind date . The sidewalk near the site on Second Avenue had been closed to pedestrians for weeks following the blast before reopening .
