Traffic crosses the George Washington Bridge, in Fort Lee, N.J., Saturday, Jan. 11, 2014. The September lane closings near the George Washington Bridge that caused huge traffic jams and now threaten the rise of Republican star Chris Christie violated federal law, a chief official said in an email ordering the lanes reopened. The Sept. 13 email was among thousands of pages released Friday by a New Jersey legislative committee investigating the scandal, which could haunt Christie's expected run for president in 2016. The documents mostly involve the Port Authority of New York and New Jersey, the agency that runs the heavily trafficked bridge. (AP Photo/Richard Drew)

About 17.3 million _ 6 percent of all Americans _ live within 50 miles of the Indian Point nuclear reactor, according to an AP population analysis. That would include parts of New Jersey and Connecticut and all of New York City, except for a chunk of Staten Island. In some accidents, New Yorkers would presumably head west to New Jersey using the George Washington Bridge, the Lincoln Tunnel and the Holland Tunnel _ passageways that are rarely light on traffic.

BACK TO SLIDE
SUFFERN, N.Y. (AP) - A woman and her boyfriend moved in with her uncle, stole from his bank accounts and then suffocated him before jumping to their deaths off the George Washington Bridge, police said Wednesday.
Suffern Police Chief Clarke Osborn said investigators are confident they have pieced together the strange story but acknowledged that with all three principals dead, "We may never be able to answer some of the questions."
The killing of William Valenti, 70, of Suffern, was discovered Monday by a nephew, Osborn said. The killers, identified as Nickie Hunt, 40, and Gary Crockett, 41, had tried to delay the discovery of the body by posting a note on the back door that said Valenti had been taken to a hospital, the chief said. But Valenti was in his bedroom, dead from asphyxiation.
Osborn said police have not established how he was suffocated or which person did it.
Detective Craig Long said Hunt also left a few notes, including one addressed to "the four most amazing kids this world has ever seen or ever will." He said that note did not mention the killing or admit guilt but apologized in general for the children's upbringing and Hunt's estrangement from their father.
The children did not live with Hunt.
"The tenor of the note indicates that she is going down a dark road" but does not specifically mention suicide, Long said. Crockett left no note, he said.
As detectives investigated the killing, they learned about a "family dispute" - Valenti had accused the couple of stealing more than $1,000 from him and had threatened to go to the police, Osborn said.
Several hours after the killing, a police dispatcher heard about the George Washington Bridge double suicide and mentioned it to detectives. The jumpers carried no identification, but their description - a white man and woman in their 40s - fit the suspects. The key to Valenti's Chevrolet Malibu was in the dead woman's pocket, Osborn said, and the two have since been positively identified.
Osborn said investigators believe Hunt and Crockett fled the murder scene in the Malibu, drove the 20 miles to one side of the bridge, walked out onto the span and jumped. He said the car has not been found.
Osborn said the killing was the first in Suffern in more than a decade.
He said Valenti had no relatives closer than his niece and nephew.
