TOWN OF PORTLAND, NY (WKBW) - State Police say just after 4 p.m. Monday, a vehicle driven by 37-year-old Hung Tran of Cleveland, Ohio drifted into the median along the I-90 in the Town of Portland.
New York State Police Captain Mike Nigrelli says Tran over-corrected, crossing two lanes and traveling down an embankment before striking a tree.
Nine people were in the vehicle, five adults and four children. One child was treated at the scene. All of the other victims were taken to various hospitals for treatment.
Tran's mother in law, 64-year-old Hang Phan, and Tran's wife, 36-year-old Hanh Nguyen died at Hamot Medical Center in Erie, Pennsylvania. One more passenger, a woman, remains at Hamot in critical condition, Nigrelli says.
Police say all of the victims were related and were on their way home to Cleveland when the crash happened.
Police say it's possible that Tran was fatigued. Drugs and alcohol have been ruled out as a factor.
State Police say the van only had room for eight passengers, not nine. Some victims, including the two women who died, were not wearing seat belts at the time of the crash, officials said.
Police have not decided whether charges will be filed against Tran.
