NEW YORK ( TheStreet) -- Popular searches on the Internet Tuesday include Amanda Knox after the American student convicted of murdering her roommate in Italy in 2007 was acquitted Monday.

Knox was free to return to the United States. She left her Italian prison Monday evening, less than two hours after the verdict was read, and is expected to arrive in the U.S. Tuesday afternoon.

Knox and her boyfriend, Raffaele Sollecito, were convicted of sexually assaulting and murdering Knox's British roommate, 21-year old Meredith Kercher. Knox received a sentence of 26 years in prison, Sollecito received 25. The two had remained in prison since November 6, 2007 -- four days after Kercher's body had been found.

The prosecutor in the case confirmed that he intends to appeal the acquittal to Italy's highest court.


United Auto Workers is also trending. Ford ( F) and the UAW reportedly have reached a tentative deal that will prevent hourly workers from going on strike.

Details of the new labor contract were not immediately released, though reports speculate more jobs can be expected at the company.

UAW is currently going through negotiations with Chrysler as well, and the union agreed to a labor deal with General Motors ( GM) last month.


"TSA machines is another popular topic. The Transportation Security Administration has purchased document-checking machines that could improve security and help lines move faster at the airport.

The machines will scan and match a passenger's boarding pass with his or her government-issued ID, while also verifying that both documents are authentic. The machines will aid the workers who currently check documents, and will notify them if either document cannot be validated.

The TSA plans to begin testing these machines early next year.
