At least six people have been killed in a Amtrak derailment in Washington state on Monday morning, with dozens more injured.

KATU reports that authorities have confirmed six deaths and 77 more injured victims after a high-speed Amtrak train derailed near Tacoma, and part of the train fell from a freeway overpass  into Interstate 5 during the morning rush hour commute.

An official reportedly told the news station that a “track obstruction” is believed to be the cause of the deadly accident. As CrimeOnline previously reported, Monday was the first day Amtrak had rolled out a new high-speed service on the route between Seattle and Portland, and city officials had cautioned that the new service would cause serious accidents.

Investigators have not yet revealed the identities of those killed or injured, and one victim is reportedly in critical condition.

According to KATU, the Amtrak train was carrying 78 passengers and five crew members when it derailed. It was reportedly traveling at a speed of 81.1 miles per hour just before the deadly accident, in a zone with a speed limit of 79 mph.

CrimeOnline will continue to provide updates as more information becomes available.
