Five killed including a baby in Pennsylvania horror crash after driver swerved into enormous tractor trailer

Five people were killed in a Pennsylvania horror crash on Tuesday after the driver of their vehicle swerved into the path of an enormous tractor trailer, killing everyone in the car. 

The incident occurred on New Meadow Run Drive in Warton Township around 1:30p.m. on Tuesday, according to state police.

The victims were  Harold Nibert, 55, Bradley 'Scott' Thivener, 47, Krystal May, 36, Amanda Dawson, 33, and Amanda's son Kullen Dawson, 7 months.

Nibert was the driver of a black Honda Accord heading eastbound that crossed the double yellow line and hit the tractor trailer head on, according to the corner's office.

It remains unclear what prompted him to swerve into the tractor trailer, or what the relationships between the passengers were.

'No one wants to see a child involved. Today was just one of the days I wish I didn't have to experience,' Farmington Volunteer Fire Department Fire Chief Brian VanSickle told WPXI on Tuesday.

'That stretch of road is a dangerous stretch of road. We've had, over the years, numerous fatalities. Today's event was probably the worst one we've had.'

The corner said all the victims were from Delaware, Ohio and in the same car at the time of the crash. 

Thivener's brother, Robb Thivener, told DailyMail.com: 'Scott, as most knew him, was a bright light and a friend to everyone he met. He had a big heart and always helped those in need if he could.'

'He was a big personality in a lil body, and there was always laughter that surrounded him with his quirky sayings and sarcasm. Thank you to all of the friends and family that have reached out. The outpouring of support from strangers from Pennsylvania and Ohio is heartwarming as well. 

'As one of Jehovah's Witnesses, he had the hope of an earthly resurrection in paradise soon to come, so until we see each other again little brother. You will be incredibly missed,' said Robb.

Another one of his brothers, Michael Thivener, said on Facebook: 'No doubt, Scott was one of a kind. I love you little brother, and I'm gonna miss you so much.'

A friend of Dawson's, Bambi Rogan, said: 'My heart aches as I found out my ex General Manager Amanda Dawson was in a fatal crash. I will miss you beautiful lady and may God be with your family.'

According to her LinkedIn profile, Dawson worked in the food industry and was a general manager at Barrio Tacos. 

'The investigation is ongoing with the collision analysis and reconstruction specialists on scene,' said Pennsylvania State Police Trooper Kalee Barnhart.

Sources told KDKA-TV that a witness reported to police that the driver of the Honda made an illegal pass before the crash and speed may have been a factor. 

All five victims were pronounced dead at the scene. Two people in the other vehicle and the truck driver have minor injuries, reported WBNS.

The Pennsylvania Department of Transportation reportedly shut down Route 40 in both directions between the intersection of Route 381 and the intersection of Dinner Bell 5 Forks Road and Dinner Bell Ohiopyle Road due to the crash until 7 p.m.
