The father of a man injured in an ATV crash earlier this summer took to social media to say his son, 20-year-old Cullen Dwyer, has died.
Dwyer was found semi-conscious off West Street in Sanborn back in June.
Niagara County deputies said it appeared as though he lost control of the ATV and crashed in an open field.
Investigators say he was alone and did not wear a helmet.
Cullen's father said he died late Friday night at ECMC.
