question:
Cook County Sheriff Tom Dart  is going to court to unmask the person who alleged in emails to politicians  Chicago police investigators and journalists that  Dart  attacked  his  wife at their South Side home.
 Dart  filed the legal papers Wednesday in his personal capacity  not as sheriff  and hired lawyer John F. Winters Jr.  who specializes in defamation cases. Such court filings are often a prelude to a defamation lawsuit filed against the person behind anonymous emails or web postings.
“ Tom  has been subjected to sustained attacks on  his  integrity  and even threats to  his  life  during  his  tenure as sheriff ” said Dennis Culloton  who is acting as  Dart ’s personal spokesman  in a statement. “Over the past several months  these attacks have escalated to include false and vicious rumors involving his wife and family  perpetuated by cowards who hide behind fake email addresses and anonymous blogs. Through this filing we hope to hold those people accountable.”
The first of two October emails cited in the filing allege  Dart  “committed a Domestic Battery” on his wife “causing visible injuries to her face” that were observed by responding Chicago and Cook County sheriff’s police on either Oct. 11 or 12. They allege a police report was taken but that the attacker was listed as “unknown” and that a 911 call was placed to  Dart ’s home.
“This incident is being attempted to be swept under the rug ” the email’s author  who describes himself as a “Cook County taxpayer” named “Dan ” writes.  “Tom Dart  should not be able to get away with this!”
Records show a complaint was also made to a Chicago police oversight agency in October alleging that police refused to act or take reports “in regards to an incident that occurred at  Sheriff Tom Dart’s  home that involved  his  wife and  his  girlfriend.”

question:
When  Ava Gardner  first met Frank Sinatra in 1943   the duo  couldn’t have suspected that six years later  after the actress faced two disastrous divorces before the age of 25  they would happily dive into a controversial love affair.
Sinatra may have still been married  but an insistent  Gardner  reportedly made the singer ask Nancy for a divorce. The mother of  his  three young children initially refused  but she eventually granted Sinatra a divorce in 1951. One week after  his  divorce was final  Sinatra married Gardner.
“I don’t think [Frank] wanted to hurt Nancy ” said Uzarowski. “But at the same time  I don’t think  he  went out of  his  way to hide [the affair]. They did get into quite a lot of trouble with the public. There were angry letters  hate mail coming in every week to the studio.
“She really liked  Ava  ” said Uzarowski. “She could have had a very bad attitude towards  Ava  because she basically stole her father away from her mother. She could have been resentful. But there was none of that… Tina and Nancy were both very friendly with  Ava .”
“The first time she met  Ava   when she was a little girl of 4 or 5   Ava  got down on her knees so she [could] have eye contact with her ” said Uzarowski. “And she really treated her with a lot of attention and a lot of warmth. That obviously really impressed her as a child. She still remembered that after all of these years.”
Still   Gardner  and Sinatra wouldn’t share a happily ever after. Their marriage was plagued by jealousy  fiery tempers and insecurity. They also publicly battled. The relationship was reportedly so tumultuous that  Gardner  had two abortions during their marriage  which she later publicly admitted.
According to Tina   Gardner  later wondered what the couple could have done differently.
The marriage lasted for less than two years. In 1953  MGM announced their separation. Then in 1957   Gardner  and Sinatra were divorced. However  they apparently never got over each other. There were even rumors of a possible reconciliation.
 Gardner  would move on and live a quiet life in London for more than 30 years  seeking salvation from the paparazzi.  She  never remarried.
One of Sinatra’s biggest tragedies would come in 1990 when  Gardner  died at age 67 of pneumonia.
“[Tina] said it was such a huge blow to  him  ” said Uzarowski. “ She  said  he  never got over it… It was such a huge shock to  him .  She  was the love of  his  life  by all accounts. When  she  did pass away   he  was devastated.
"Tina said the actual pain  he  experienced was so much more.  He  wouldn’t share that with anyone because it was too personal… There was a story that Nancy said in another book that  he  just locked  himself  in a room for 24 hours… and wouldn’t speak to anyone.”
answer:
Ava Gardner and Frank Sinatra's marriage resulted in two abortions but their love endured says author

Gaslyâs absence from Austin has paved the way for New Zealander Brendon Hartley to replace him at  Toro Rosso  and make  his  Formula One debut in Sundayâs race at the Texas track.
 The Frenchman  is expected to return to Formula One for the remaining three rounds after Austin and to take on a regular race drive in 2018.
Hartley acquitted himself well in Friday practice  completing more than a race distance  and could also be in the frame for a race drive next year if  Toro Rosso  decide to drop Russian Daniil Kvyat.
The driver turmoil at the Red Bull-owned team is a consequence of Kvyatâs poor performances this season and Spaniard Carlos Sainzâs move to Renault as part of an engine deal that will see  Toro Rosso  switch to Honda in 2018.
