Officials say a sixth Memphis officer was fired Friday after an internal police investigation showed he violated multiple department policies in the violent arrest of Tyre Nichols, including complying with rules surrounding the deployment of a stun gun. Preston Hemphill had previously been suspended as he was investigated for his role in the Jan. 7 of Nichols, who died three days later. Five Memphis officers have already been fired and charged with second-degree murder in Nichols’ death. Hemphill was the third officer at a traffic stop that preceded the violent arrest but was not where Nichols was beaten. Body camera footage from the initial stop has Hemphill saying that he stunned Nichols and “I hope they stomp his ass.”

A jury has decided Elon Musk didn’t deceive investors with tweets in 2018. The verdict by the nine jurors was reached after less that two hours of deliberation following a three-week trial. The trial pitted Tesla investors represented in a class-action lawsuit against Musk, who is CEO of both the electric automaker and the Twitter service he bought for for $44 billion a few months ago. In 2018, Musk tweeted that he had the financing to take Tesla private even though it turned out he hadn’t gotten an iron-clad commitment for an aborted deal that would have cost $20 billion to $70 billion to pull off. The verdict is a major vindication for Musk.

The mayor of Austin, Texas, has apologized and says the city failed to communicate with its residents after a winter storm left thousands without power for days. Mayor Kirk Watson said at a news conference Friday that “the situation is unacceptable to the community, and it’s unacceptable to me.” Rising temperatures are offering some hope for frustrated Texans. Meanwhile, a new wave of frigid weather has begun rolling into the Northeast and led communities to close schools and open warming centers. Wind chills in some higher elevations of the New England could dive below minus 50.
