This happened last Sunday night - 5pm - June 27th, in Lancaster PA, and it's now starting to make national news. Investigators are still trying to figure out what happened. Three motorcycles collided with a taxi van in Lancaster, PA. Witnesses said it sounded like three shotgun shots going off. There was only one person in the van, but all three motorcycles were double up. The van was hit in the front and both sides. The van caught fire. All of the motorcycle riders except for one passenger died. And she's still in critical condition in the hospital. Later investigation appears to show that the van went left of center into the motorcycles. Speculation is that the taxi van driver had a stroke or seizure. Confusing the investigation is a wire from poles hanging down across the road, at the scene of the accident, and it's unknown why. Investigators have assembled a team to determine what happened, and don't expect results for weeks or months. This is a terrible accident, and I think we can all say our sympathies and condolences are with the families in their time of grieving. LancasterOnline newspaper WGAL8 - Cause of crash remains unclear
