Investigators seek answers after Russian plane crash
Investigators are working to determine the cause of the crash of a Russian airliner in Egypt's Sinai peninsula early Saturday that killed all 224 people on board. A Russian aviation official said Sunday that the plane broke apart in the air, but that the cause was still unknown. A local affiliate of the Islamic State claimed responsibility for the attack but Russian and Egyptian officials said the group lacks the capability to shoot down a commercial airliner. Two major European airlines, Germany's Lufthansa and Air France, don't seem to be so certain, announcing Saturday that they would immediately stop flying over Sinai for safety reasons until the cause of the crash was determined.
NYPD investigates deadly Halloween crash
A driver who plowed his car into a group of trick-or-treaters in New York City, killing three people, may have suffered a seizure, according to police. Police believe the driver may have had a seizure or experienced some other medical problem and lost control of his car, but investigators have not yet confirmed this as the cause of the crash, police said. A 10-year-old girl and her grandfather were among those killed. Dozens of children and their families were along the street in the Bronx around 5 p.m. Saturday when the car veered out of control.

Do-or-die time for the Mets
Sunday finds the New York Mets on the brink of elimination going into tonight's Game 5 of the World Series versus the Kansas City Royals. Disaster struck New York in the eighth inning of Game 4 Saturday, when Kansas City scored three runs in a 5-3 win. Kansas City now leads the series, 3-1. The rally was fueled in part by an error by playoff hero Daniel Murphy, who let a soft ground ball bounce under his glove, allowing the Royals to score the tying run. New York will send Matt Harvey (13-8, 2.71 ERA; 2-0, 3.38 ERA in postseason) to the mound tonight versus Kansas City's Edinson Volquez (13-9, 3.55 ERA; 1-2, 4.37 ERA in playoffs).
