[Q]: Delonda Walker  alerted police Tuesday after suspect Howell Donaldson III  24  handed  her  a McDonald's food bag containing a .40-caliber Glock  which Tampa police later said matched the murder weapon used in all four shootings that occurred in the Seminole Heights neighborhood between Oct. 9 and Nov. 14.
Donaldson allegedly told  Walker  that he planned to leave the state.  Walker  then approached a police officer who happened to be at the Ybor City McDonald's to turn over the bag  officials said.
In a statement read by Buckhorn in a press conference Friday   Walker  said  "receiving a reward never entered my mind."
"I went to work on Tuesday intending to serve customers and do my job. The day turned out very differently "  she  said. "When confronted with this situation  I wanted to do the right thing and I reached out to a nearby police officer."
 Walker  said  she  is "grateful" that  she  was able to assist law enforcement but requested privacy amid the ongoing investigation.
"... I appreciate all the well wishes and kind words from our community "  she  said.
Buckhorn praised Walker for  her  actions.
" She  is what’s right about this city " Buckhorn said.

[Q]: NBC will broadcast the Ceremonies again in prime time tonight  at 8 p.m. Eastern. This version will have commentary from hosts Katie Couric  who was tapped to place Matt Lauer after his firing  and Mike Tirico  who replaced  Bob Costas  as NBC’s prime-time host after a nearly three-decade run.
Tirico made his prime-time debut Thursday night. The Washington Post’s Rick Maese caught up with him before the Games to learn more about his new high-profile assignment. “I think trying to be  Bob  would be stupid. And that was one of  his  bits of advice: Be yourself ” Tirico said. “So I’m going to try to do that.” For the full Q&A  scroll down to the “Olympics Corner” section of this newsletter.
For 11 straight Summer and Winter Games — dating back to 1992 —  Bob Costas  served as the familiar and reliable face of the Olympics. But  Costas  is sitting out the PyeongChang Games and has passed the torch to Tirico  who will serve as NBC’s prime-time host  starting with Friday’s Opening Ceremonies. Tirico joined the network in 2016 after more than two decades at ESPN and was a daytime host of the Rio Games. He recently spoke with The Washington Post’s Rick Maese about his new high-profile assignment.
Q: It’s not like you’re a newcomer to this broadcasting game  but did you seek out  Costas  for any advice?
A: There’s been a longtime friendship there. I don’t think that’s overstating it. And I can’t imagine this job changing hands more smoothly.  Bob  has been unbelievable in making  himself  available  if I have any questions. I know I can pick up the phone during the Games  and if I have a question  I know I’ll get an honest answer.  Bob ’s the all-time best.  Bob  set a standard for the amount of times  he  did this and the way  he  did it that likely won’t be matched ever again. So I’m not replacing  him ; I’m following  him . I think trying to be  Bob  would be stupid. And that was one of  his  bits of advice: Be yourself. So I’m going to try to do that.

A: The best piece of advice that I got from  Bob  and from Al [Michaels] before the Rio Games working daytime: You don’t have to know everything about everyone. It’s impossible. The experts at each sport have that covered. In the host role  you just need to have the overriding story lines. I’m trying to get to the top of the surface. It’s like one of those fancy Starbucks drinks — you do want to get some of the coffee  but you want to make sure you get all foam. But how has my life changed? I’m sitting in my office right now. Two years ago  I certainly would be watching a replay of a Big Ten or an NBA game from the night before. And right now I’m watching the women’s skeleton competition from Germany. And it’s the fourth different Olympic event that I’ve watched since I’ve been up this morning.

[Q]: Mikaela Shiffrin makes it all looks so easy sometimes. For the world’s most dominant female ski racer  the trip from the starting gate to the medals podium is a well-trodden path.
Two difficult runs on Friday offered a harsh reminder for  Shiffrin  and the world just how difficult this medal pursuit could be  how difficult it will be to leave PyeongChang with a suitcase full of gold. Less than 24 hours after winning the giant slalom   Shiffrin  was back on the course at Yongpyong Alpine Centre to defend  her  Olympic gold in the slalom.
But at the Winter Games  things don’t always go as planned  and in  her  most dominant and consistent discipline   Shiffrin  finished in a disappointing fourth place  endangering  her  hopes of leaving here with multiple medals.  Shiffrin ’s total time of 1:39.03 was 0.40 seconds behind first-place finisher Frida Hansdotter of Sweden and just 0.08 seconds away from a spot on the podium.

 Shiffrin  seemed to know from the start of the day that something was amiss. Before  her  first run   Shiffrin  stood at the top of the course and vomited before launching down the hill.
“I just had this terrible feeling ”  she  explained later. “It was almost like a food poisoning feeling  like what is happening? I felt like my warm-up skiing was good  my turns and my free skiing was good. But when it came to putting it into the race  I was not like myself at all.”
 Shiffrin  has been open about  her  competitive anxieties and  her  ongoing battle with nerves. Last season  she  frequently became ill before races and sought the help of Lauren Loberg  a sports psychologist who works with the U.S. Ski and Snowboard Association.
On Friday in PyeongChang  in  her  best discipline and with an empty stomach   she  wasn’t  her  usual dominant self and clocked a time of 49.37 seconds  the fourth-best of the day’s initial runs. Entering the second run   she  trailed Switzerland’s Wendy Holdener by 0.48 seconds  not an insurmountable margin by any means.
“Rather than just focusing on the good skiing I know I can do  I was conservative ”  Shiffrin  said. “I was almost trying to do something special. I don’t need to do something special. I just need to ski like  myself  and it’ll be fine.”
Of the 2 900 athletes competing in the Winter Games  few are as dominant in their chosen discipline as  Shiffrin  has been in the slalom. In addition to the Sochi title   Shiffrin  has won the past three world titles  dating to 2013 when  she  was all of 17 years old.  She ’s now 22 and already has won 30 World Cup slalom events; only two female skiers all time — Austria’s Marlies Schild (35) and Switzerland’s Vreni Schneider (34) — have more. And  Shiffrin  has won the World Cup slalom title five of the past six years. (In 2016   she  missed two months of competition because of a knee injury but still won all five slalom races  she  entered.)
 She  had about four hours before  her  second run  enough time to nap  regroup and calm  her  nerves. Coming from behind is not a familiar position for Shiffrin  in large part because it’s such unfamiliar territory. This season  she  has competed in seven World Cup slalom races.  She  led after the first run in six  eventually winning five and finishing second in another. The only slalom  she  didn’t lead this season was Jan. 9 in Flachau  Austria  where  she  was second  trailing only one racer — Austria’s Bernadette Schild — by 0.37 seconds. She scorched through her second run and won the race over Schild by nearly a full second.

 Shiffrin  came to PyeongChang contemplating as many as five races. But weather wiped out two days of competition  forcing Olympic officials to shuffle and condense the Alpine schedule. For  Shiffrin    it  meant races wouldn’t be spaced out as much and  she  wouldn’t have as much time to rest and prepare for the speed events.

 Her  team decided to pull out of Saturday’s super-G race and haven’t yet made a final decision on next week’s downhill  though the combined is still likely. Having to open these Olympics racing the giant slalom and slalom on back-to-back days was exhausting in every way  Shiffrin said.
