At about 2:30 p.m., troopers responded to the accident involving six vehicles on southbound Interstate 684 south of exit 4 in Bedford.
Police say the preliminary investigation revealed that a box truck operated by 59-year-old Henry Valencia of the Bronx was unable to stop due to icy road conditions and struck another vehicle which was stopped in traffic.
The driver of that vehicle, 40-year-old Kerry Hamill of Lee, Massachusetts was killed along with a 3-year-old passenger.
Hamill's wife, 40-year-old Lauren Pellegrino, survived the crash and was transported to Westchester Medical Center for minor injuries.
The initial collision created a chain reaction involving four additional vehicles, police said.
Occupants of the other vehicles suffered minor injuries.
