Can i sue a newspaper?

in 2008 FBI raided my familys house with allegations of human trafficing,money laundering,social security fraud and a foced abortion (allegations were agains my parents),my parents faced 108 criminal counts and 50years+ in federal prison. With the help of our attorneys we were able to build a strong defense in wich we went to mexico to interview several alleged slaves, whom all sided with us, saying there was no such abuse, even the woman who was allegedly foced to abort brought along documents stating it was an ectopic pregnancy that had to be terminated, NOT an abortion. The government later too dropped the money laundering charges because they admitted it was a mistake, and as it turns out one by one the charges began to fall...eventually 107 of the 108 charges were dropped because the government could not back up its allegations. the one count was for having an undocumented employee working with us for two months( http://www.mercurynews.com/crime-courts/ci_18266040?source=rss ). Several even grander allegations were reported by a hispanic news paper based in Los Angeles which exaggerated stories and even went as far as claiming my family had a contracted hit man working for us. the reporter who wrote these news paper articles claims she did some investigative reporting with some supposed slaves and collaberated with the FBI in their investigation, it turns out she was interviewing two disgruntled employees who wanted to gain legal residency from this. i want to know if i can effectively sue a news paper for not doing a detailed investigation on such a heavy case? what can i do? do i have a case? might the FBI be liable as well?
