[Q]: The Las Vegas hotel room used in a mass shooting that killed 58 people will continue to remain unoccupied.
  Stephen Paddock  opened fire earlier this month from the corner suite on Mandalay Bay Resort and Casino's 32nd floor before taking  his  own life  and the hotel says it will not rent  the room  again.
"This was a terrible tragedy perpetrated by an evil man. We have no intention of renting  that room  " MGM Resorts International  which owns the property  said in a statement to the Las Vegas Sun.
It was not immediately clear whether  the room  will be used for some other purpose or be marked in any way with a remembrance of those who died on the concert grounds below  the room .

[Q]: It's still unclear why it took over 36 hours to recover Sgt.  La David Johnson's  body from the battle space. The official told ABC News that  Johnson 's locator beacon was giving unclear reports  and  he  seemed to be moving.
" Johnson 's equipment might have been taken " the official said. "From what we now know  it didn't seem like  he  was kidnapped and killed.  He  was somehow physically removed from where the combat took place."
On Thursday  Joint Staff Director Lt. Gen. Kenneth McKenzie told reporters that  Johnson  was "separated" but "no one was left behind." That idea was echoed by Secretary of Defense James Mattis during a meeting with the Israeli Defense Minister.
It was nightfall when U.S.  Nigerien  and French forces searched for  Johnson .
