[EX Q]: Leading up to the Olympic figure skating menâs event   Nathan Chen  was a gold medal favorite.  Chen âs teammate Adam Rippon  who does not perform some of the more difficult jumps that  Chen  does  wasnât considered a true threat for a medal in the olympic skating menâs event  but managed to endear  himself  to the world with  his  exuberant â and clean â skate.
Now Rippon sits ahead of  Chen  after the Olympic figure skating menâs short program. Ripponâs error-free skate  albeit minus the quad jumps  landed  him  in seventh place while teammate Vincent Zhou is in 12th.  Chen   who made mistakes on all of  his  jumps  is currently 17th. That means  he  will skate in the second group of six skaters in the free program tomorrow  since the skating order is reversed from the rankings after the short program.
 Chen   who is competing in  his  first Olympics  is having a tough time so far. First there was his error-filled short program in the team skating event earlier this week  in which he botched all of his jumps. Then he did the same in the menâs short program.
 Chen âs arsenal of quadruple jumps sets  him  apart from most of the competition; quadruple jumps are worth far more in points than triples are  and itâs easy for  Chen  to add up points and pull away from the field â if  he  lands them cleanly.
The disastrous short program prompted tweets of encouragement for  Chen   including from Olympian Scott Hamilton. âI respect you. I admire you. I believe in you. Today was a difficult day. Tomorrow is up to you!â
But even if  Chen  skates a dazzling long program peppered with multiple quad jumps  itâs numerically impossible for  him  to climb from 17th place into medal contention â unless most of  his  higher-ranking competitors all come down with the norovirus. âIâve never been in this position before so I donât really know exactly what to do â  he  says.
Even before the menâs short began  Olympian and silver medalist Paul Wylie questioned the fluidity and uncertainty of so much of todayâs Olympic athletesâ schedules.  Chen  has said  he  regularly changes the elements of  his  program  switching jumps depending on how  he  is feeling and whether  he  needs to perform the more challenging ones to game a competition. âI am not a fan of the ultra fluidity of the planned program content â Wylie said. â Nathan  is dealing with a lot of variables. The other variable is  Nathan  is always talking about  his  boots;  he âs got three different pairs of boots. And  he  has been going away [from Gangneung] to practice. So  he âs thinking  where am I practicing today. Iâm not sure those question marks are really what you need in the Olympics.â
Maybe what  Chen  needs is some of teammate Ripponâs infectious exuberance. âIâm able to go out in the individual menâs event and show the world I am a cutthroat competitor and that Iâm an awesome skater â Rippon says. âAnd I want to show why everyone should be involved in skating because it is something that has brought me so much joy  and can bring a lot of other people a lot of joy as well.â

[EX Q]: Tyler Barriss   the 25-year-old man suspected of making a fatal prank "swatting" call to police after an argument over the video game Call of Duty  has waived extradition to Kansas  according to the Los Angeles District Attorney's Office. The fugitive from justice warrant lists  Barriss'  charge as making a false alarm  according to NBC News.
Authorities in Los Angeles arrested  Barriss  on Friday. Wichita police say they received a call on Thursday from someone claiming they had killed their father  doused the home in gas  and planned to set it on fire with their mother and brother inside. Police went to the given address  where they found 28-year-old Andrew Finch. Finch was fatally shot during the incident.
This isn't the first time  Barriss  has been arrested in connection to a fake 911 call. In October 2015  police in California arrested  Barriss  for making bomb threats to KABC-TV. He was charged with two felony counts of false report of a bomb to an agency of business and one felony count of criminal threats. According to Los Angeles Sheriff's Office records   Barriss  was sentenced to 972 days in the adjudicated case.
Now that  Barriss  has waived extradition  he will be transported back to Kansas within the next two to three weeks. When he arrives in Wichita  he will make his first appearance in a district court. Glixel has reached out to the DA's office to see if  Barriss  faces any additional charges.
