UNDATED (AP) – Authorities looking into the dead-of-night crash on a Pennsylvania interstate that killed five people say a loaded passenger bus passed a truck shortly before the wreck.

A National Transportation Safety Board member said Monday an initial report about the incident should be out in about 10 days, and a more detailed analysis could take two years.

Dozens were injured in the crash at about 3:30 a.m. Sunday on the Pennsylvania Turnpike east of Pittsburgh.

Five people were killed and at least 60 more injured during a deadly pile up on a Pennsylvania highway Sunday morning, shutting down almost 100 miles of the Turnpike in both directions. Multiple vehicles were involved in the crash including two tractor trailers and a tour bus on the westbound side of the highway.
