Michelle Damron Hulinek, 30, of Bushnell, remained in critical condition on Saturday at Tampa General Hospital after an accident Friday afternoon on Interstate 75 that triggered a multi-car pileup. Police said Hulinek's Ford Explorer flipped after she swerved to avoid a semitrailer truck about a half mile into Sumter County. She was thrown onto the road and later was flown by helicopter to Tampa General Hospital. Seconds after her accident, a refrigerated semitrailer truck smashed into the back of several vehicles that had stopped to avoid hitting Hulinek. The accident snarled traffic on I-75 past State Road 50 for several hours.
