NORTHAMPTON, Mass. (AP) — Authorities say a man involved in a head-on collision in Northampton died after going into cardiac arrest.

The district attorney's office says 57-year-old Michael Sims, of Northampton, was driving south shortly before 11 a.m. Sunday when his vehicle crossed over the center line and collided with a northbound vehicle.

A Northampton Fire Department spokesman tells The Daily Hampshire Gazette (http://bit.ly/1f3lQ0Q ) EMTs found the man in the midst of cardiac arrest and attempted to revive him at the scene.

The woman driving the other vehicle told responders she tried to avoid the man's car when he swerved into oncoming traffic, but could not.

Both were taken to Baystate Medical Center in Springfield. Sims was pronounced dead there. The woman's injuries are not considered life threatening.
