Two twin girls died as they slept when a huge tree smashed into their bedroom after being ripped from the ground in a deadly tornado . Emily and Kenni Bisson were killed in the 105 MPH winds, which struck Oneida County in New York . The young girls' trapped mother Kayleigh Bisson, 37, could be heard screaming after the roof of their home collapsed. The storm also killed another person, Shelly Johnson, 50, who was hit by another tree while trying to escape the storm. "It's just an awful, tragic thing, and it's obviously shaken up a lot of the first responders," Oneida County Sheriff Robert Maciol said in a press briefing. "This community has come together as our communities certainly have a long history of doing that when tragedy occurs." Neighbour Jared Bowman told Syracuse.com that the young family had recently moved into the house. He said he was powerless after seeing the maple tree with twin trunks smash through the property. "She was yelling 'Get my kids out!' but there was no noise. It felt very eerie and bad," he said after the tragedy, which took place in the early hours of Sunday morning. Clark Mills Fire Department serviceman Rick Carollo discovered the girls had no pulse once they had been located. "I found the mother in the front window," he told the outlet. "I had to climb a tree to get her out." The children's school was closed on Monday as a mark of respect. Emily and Kenni were first-graders at Clinton Elementary School and superintendent Christopher Clancy confirmed the deaths parents in an email. “Earlier today, a severe weather emergency in our community resulted in the tragic loss of life, including two of our elementary students,” he wrote. “Our hearts are with all of the families and loved ones affected by this tragedy.” A GoFundMe page set up to help Kayleigh pay for funeral expenses and try to recover from the ordeal has so far raised almost $300,000, around £220.000.
