Investigators are still trying to figure out what exactly caused a deadly two car collision around 8:30 Wednesday morning.
Police say 71-year-old Martin Peters of North Tonawanda was driving south on Niagara Falls Boulevard near Irvington Drive when he crossed into the northbound lanes and struck 38-year-old Nicole Keefe of Buffalo head-on.
Both drivers suffered serious injuries and had to be extricated from their vehicles.
Peters was later pronounced dead at DeGraff Hospital. Police say he may have suffered a medical condition before the crash.
"I believe one witness described it," said Captain Patrick McKenna, Amherst Police Department, "once the gentleman kind of put his head down the car sped up so his foot may have just hit the pedal causing an increase in his speed coming into the other lane."
Two other drivers had their vehicles damaged in the accident, but neither were injured.
Both lanes of traffic were closed between Ellicott Creek Road and Creekside Drive, causing significant delays to the morning commute. Niagara Falls Boulevard has since re-opened.
