[EX Q]: Saint Nicholas of Myra (now Demre)  was known for  his  anonymous gift-giving and generosity. People believed  he 'd put coins in the shoes of anyone who left them out for  him  on  his  feast day  Dec. 6.
As the story goes   he  was a monk who gave away  his  hefty inheritance and instead chose to help the poor and the sick.
 He 's also a patron saint of sailors and was  of course  especially fond of children. (There's one slightly bizarre story  more Halloween than Christmas  of  St. Nicholas  saving three children who had been "lured into the clutches of an evil butcher.")
It wasn't until the 16th century that  St. Nicholas  began to take on  his  modern  candy-cane hued form in images and imaginations. In Europe  he became known as Father Christmas.

[EX Q]: Sarah Ferguson  the Duchess of York  has seemingly been silenced after she published a series of odd tweets following the announcement that  her daughter Princess Eugenie  is engaged to Jack Brooksbank.
On Monday  Princess Eugenie  the daughter of Prince Andrew and his ex-wife Sarah Ferguson  announced  her  engagement to Jack Brooksbank. Following the nuptial news   her  mom  Fergie  took to Twitter.
The happy mother tweeted five separate posts featuring romantic photos of  Eugenie  and Brooksbank with detailed greeting card-like captions on each photo.
Fergusonâs first tweet of the day was a black and white image of the couple which read in a Hallmark card-style font: âA total embrace of goodness AND JOY  we love jack and I AM SO EXCITED to have a son  a brother and a best friend   Eugenie  is one of the finest people I know and so together it will BE PURE HARMONYâ #total joy #engagement @TheDukeOfYork.â

âJack is an absolutely outstanding young man and  Eugenie  and he have got to know each over a number of years  and Iâm really thrilled for them â Andrew said. âI canât speak for the Duchess but weâ¦ and for [Eugenieâs sister] Beatrice ... we are overjoyed today that  Eugenie  and Jack have got engaged.â

[EX Q]: A Cook County Stateâs Attorney asked the detective   Reynaldo Guevara   74  to review police reports and testimony  he âd previously given in the case.  Guevara  refused  quickly flipping the pages and then handing them back.
Seated in the courtroom gallery were family members of 11 people who say  Guevara  framed them  and four more people whom  Guevara  helped put in prison but whose convictions have since been overturned.
âThis morning I prayed that maybe God would touch his heart and he would tell the truth â said Esther Hernandez  the mother of two sons who claim  Guevara  framed them in a 1997 murder.
âThatâs an acute case of amnesia â said Jose Montanez  who was exonerated last year of a 1993 murder after spending 23 years in prison.  Guevara  was one of the lead detectives on  his  case.
Since 2009  when a federal jury issued a record $21 million to a man whom  Guevara  was found to have framed  the retired detective has repeatedly invoked the Fifth Amendment and refused to testify.
But earlier this year Cook County State's Attorney Kim Foxx offered  Guevara  immunity in exchange for his testimony. His lawyers argued he would still be vulnerable to perjury charges.
Todayâs hearing was part of an appeal by two defendants  Gabriel Solache and Arturo Reyes  who say that  Guevara  beat confessions out of them. Prosecutors called  Guevara  to the stand to rebut that claim. Since he testified he didnât remember the case  prosecutors asked the court to allow  Guevaraâs  previous testimony from two court appearance in 2000.
âI hope people know how fucked up that is â said Jennifer Bonjean  an attorney representing other  Guevara  clients. âItâs pretty mindblowing that the state is literally vouching for the prior testimony when  Guevara  wonât  himself .â
An attorney for Solache  Karen Daniel  told the court that  Guevara  was âdisavowing  his  prior testimonyâ in the 2000 case and that  he âs essentially pleading the Fifth âunder a different guise.â
The state has called several other officers  prosecutors and medical personnel who were at the police station the night of the alleged beating. They testified that neither defendant complained of abuse. A paramedic called to the stand today testified he conducted medical evaluations of both defendants two days after  Guevara  allegedly beat them and didnât note signs of abuse.
In 2013  Chicago hired a law firm to conduct an independent investigation of allegations of misconduct by  Guevara . Those investigators rejected Solache and Reyesâs innocence claims but called the case against them âvery thin.â
