A crash on Route 1A Wednesday morning involving a shuttle bus from Logan Airport left two people dead and four others hospitalized, state police said. 

A Subaru Legacy operated by a man from Swampscott and a hotel shuttle transporting passengers from Logan crashed on the A1 northbound around 1 a.m., past the Ted Williams Tunnel. The Subaru struck the rear of the shuttle, owned by the Hampton Inn, causing it to veer and strike the barriers, officials said.

Two bus passengers, a 58-year-old man and a 47-year old women, both from El Paso, Texas, were ejected from the vehicle and were pronounced dead at the scene, police said.

The driver and two other passengers of the bus were not ejected but sustained injuries and are currently at Massachusetts General Hospital.

The driver of the Subaru, its only occupant, was also transported to MGH with nonlife-threatening injuries, officials said.

State police are currently investigating the crash to determine if criminal charges will be sought.
