Question: Kyle Enos  25   was sentenced to eight years in prison for selling drugs.
 He  traded fentanyl  a powerful opiate  for bitcoin to anonymous buyers.
 Enos  posted doses in envelopes at  his  local Post Office in South Wales.
Police released the text of  his  dark web sales pitch after  his  sentencing.
This is how  drug dealer Kyle Enos  attracted customers to  his  online opiate store  trading drugs for cryptocurrency on the dark web.
 He  traded in fentanyl  the powerful painkiller that can be 50 times as strong as heroin and which contributed to Prince's death  by offering customers supermarket-style "buy one get one free" deals in exchange for bitcoin.
Police also released footage from  Enos 's custody interviews  in which he describes how the drug operation works.
 Enos  told officers  he  did not make fentanyl himself  but ordered the substance in bulk every few weeks and sold smaller doses to individual customers.  He  used  his  local Post Office in Newport  South Wales  to ship the drug in envelopes.
They communicated anonymously over the dark web   he  said  in exchange for bitcoin. The footage does not give any sense of how much money  he  was making.
The text from  Enos 's storefront is in some ways very prosaic â  he  has a summary of delivery times  offers refunds and guarantees and emphasises the quality of  his  customer service.
However  the illicit nature of the exchange is also obvious from  Enos 's pre-emptive warnings about keeping receipts: Customers needed to be reassured that their information would not be preserved in case  Enos  were ever caught  which  of course  is exactly what happened.

Answer: Kyle Enos


Question: Sen. Bob Corker (R-TN)  speaks with reporters after announcing  his  retirement at the conclusion of  his  term on Capitol Hill in Washington  U.S.  September 26  2017. REUTERS/Aaron P. Bernstein
WASHINGTON (Reuters)  - U.S. Senator Bob Corker   the influential Republican chairman of the Senate Foreign Relations Committee  said on Tuesday he will not run for re-election  a blow to a party already struggling to balance divisions between mainstream and more populist wings.
An establishment Republican   Corker  has been criticized from the right  and a conservative activist had already announced a primary challenge. But he was expected to keep the seat  and had amassed a $7.5 million campaign war chest.
 Corker  has ruled out running for governor of Tennessee.
âI have no idea what Iâm going to do. No idea whatsoever â  Corker  said in an interview. But he said he was not leaving out of frustration over deep party divides that have often paralyzed Congress.
 Corker  announced  his  retirement on the day of the failure of the latest Republican effort to repeal former Democratic President Barack Obamaâs healthcare law.
âI am not going to be one of the people who leaves here badmouthing what is one of the greatest privileges of oneâs life â  Corker  said.
He said he realized he was ready to retire on Aug. 24 during a factory groundbreaking in Clarksville  Tennessee  and almost announced his decision at least twice before Tuesday.  Corker  said that he made his announcement now to allow a strong candidate time to enter the Senate race.
 Corker  is the first senator to announce  his  retirement ahead of the 2018 mid-term elections  when one-third of the 100-seat chamber will be up for grabs. Tennessee is a solidly Republican state and the party  which currently holds a 52-seat majority in the Senate  is favored to keep his seat.
In his official announcement   Corker  said that âafter much thought  consideration and family discussionâ over the past year  he and his wife Elizabeth âhave decided that I will leave the United States Senate when my term expires at the end of 2018.â

CLASHES WITH  TRUMP
In August  after Trumpâs much-criticized reaction to violence at a white supremacist rally in Virginia   Corker  told reporters in  his  home state Tennessee that Trump had not been able to demonstrate the âstabilityâ or competence that  he  needed to be successful as president.
After the exchange  the two men had an hour-long meeting at the White House this month that  Corker  has described as a wide-ranging and friendly discussion.
 Corker  will remain chairman of the Foreign Relations Committee until he leaves in January 2019. He said he wanted the panel to address issues including Secretary of State Rex Tillersonâs State Department reorganization  food aid reform  and the fight against human trafficking and modern slavery.
 Corker  said the committee would address the international nuclear agreement with Iran  as Trump faces a mid-October deadline for deciding whether to certify that Tehran is complying with that pact. That decision could force Congress to decide whether to reimpose sanctions.  Corker  would not say whether Trump had decided to certify or not.

Answer: Bob Corker


Question: MELBOURNE  Australia â It took  Caroline Wozniacki  43 majors and two failed attempts in finals before finally claiming  her  first Grand Slam singles title.
One of the first things  she  did as a champion was apologize to top-seeded Simona Halep following  her  7-6 (2)  3-6  6-4 win in the Australian Open final on Saturday night.
"I'm sorry  I'm just taking a second to hug Daphne "  Wozniacki  said  pausing as  she  clutched the winner's trophy in the on-court ceremony. "I dreamt of this moment so many years  to be here now it's a dream come true."
More than seven years after appearing in  her  first Grand Slam final at the 2009 U.S. Open â a straight sets loss to Serena Williams  â Wozniacki  can finally erase the "but never won a major" footnote that has long been attached to  her  resume.
"I'm never going to get the question again about being a world No. 1 without a Slam "  she  said after leaving the court.
 Wozniacki  will regain the top ranking next week for the first time in six years â beating Serena Williams' record of 5 years  29 days between stints at No. 1 on the women's tour â in another benefit of beating the top-seeded Halep.
 Wozniacki  lost two U.S. Open finals â in '09 and 2014 â and Halep lost two French Open finals before their meeting at Melbourne Park.

In Halep's case   she  was the first player who had saved match points in multiple matches to have reached the final.  She  saved triple match point and rallied in the third set to beat Laura Davis 15-13 in the third set of  her  third-round match  and also needed to save match points in  her  semifinal against Angelique Kerber.
 Wozniacki  saved match points in  her  second-round win over Jana Fett and later said  she  was relaxed because for the rest of the tournament  she  was "playing with the house money."
"I know that today is a tough day "  Wozniacki  said to Halep. "I'm sorry I had to win today but I'm sure  we 'll have many matches in the future. Incredible match  incredible fight. And again  I'm sorry."
Halep was playing with an injured left ankle  needed treatment for dizziness in the second set and had rallied from a break down in the third set to lead 4-3 when  Wozniacki  took a medical time out to have  her  left knee taped. In the end   she  just ran out of steam.
"It's not easy to talk now " Halep said at the presentation. "It's been a great tournament for  me . I started not very well with the ankle injury. I just wanted to give my best every match  which I did. Of course I'm sad I couldn't win today but Caroline was better than  me .
 Wozniacki  is the third first-time major winner in the four Grand Slam tournaments since Serena Williams won the 2017 Australian Open for  her  record 23rd Grand Slam title. Serena Williams  who beat  her  older sister  Venus  in last year's final  took time out for  her  pregnancy and the birth of  her  first child in September  and is preparing to return to competition next month.
Wozniaki was ranked No. 1 for 67 weeks  including 49 straight from Feb. 21  2011 until Victoria Azarenka replaced  her  on Jan. 30  2012.
 Wozniacki  got a break in Halep's first service game and had a chance to serve for the first set at 5-3  but the Romanian rallied to break back and to force a tiebreaker. After getting an early jump in the tiebreaker   Wozniacki  won the last three points to win a set for the first time in a Grand Slam final.

Answer:
Caroline Wozniacki Caroline
