Officials: Plane carrying first lady got too close to military C-17

The planes were three miles apart, when they are supposed to be five miles apart, the official told CNN. The Federal Aviation Administration is investigating what went wrong, as it is believed to be an air traffic controller mistake, the official said.
The White House does not believe the first lady's life was ever in danger, the senior official said.
The FAA said in a statement controllers at Andrews Air Force Base instructed an incoming Boeing 737 to perform a "go around" "because the plane did not have the required amount of separation" behind the military plane.

9th set of human remains thought to be found in serial killer probe

Police found what appears to be a human skull Monday on the outskirts of a bird sanctuary in Long Island, New York, a county police officer said, potentially the ninth set of remains discovered in the probe of a suspected serial killer.
Lt. Kevin Smith of the Nassau County Police Department said the skull was found around 3:30 p.m. in Oyster Bay. About four hours earlier, a New York state police officer and his cadaver dog spotted another set of remains about a mile and a half away, and authorities worked to determine whether those remains are human.
These discoveries come on the first day that authorities probing the deaths of several young women searched for evidence in and around Nassau County. Since December, eight sets of human remains have been found in Suffolk County, just to the east of Nassau County and roughly five miles from the sites of Monday's discoveries.
