LINCOLN, Neb. -- A Florida man has been arrested after a multi-vehicle crash in Lincoln that killed two people Saturday.

The crash involved eight vehicles that were all travelling westbound on I-80.

Authorities say that after an initial investigation, investigators believe that a semi driven by, 50-year-old, Yorkwind Crawford of North Miami Beach, Florida, rear-ended another vehicle that had been travelling east of the 27th Street interchange. 

NSP says the vehicle that was hit was a Chevrolet Colorado pickup. A father and son were travelling together in the vehicle, and they were both killed in the crash.

The accident remains under investigation.
