Good morning, NBC News readers.

The missing boy story we highlighted yesterday sure took a bizarre turn thanks to some DNA results.

Here's more on that and what else we're looking at today.

Americans have soured on social media, poll finds

President Donald Trump may love Twitter, but most Americans don't.

A sizable majority say Facebook and Twitter spread falsehoods rather than news and do more to divide the country than unite it, according to results from the latest national NBC News/Wall Street Journal poll.

The negative attitudes about social media are shared by Democrats, Republicans, men, women, urban residents and rural ones.

“If America was giving social media a Yelp review, a majority would give it zero stars,” said Micah Roberts, a pollster who worked on the survey.

'People are mad': Trump's border threats have El Paso on edge

Trump relented on his threats to close the southern border with Mexico on Thursday. The president said he'd give the country one year to stop the flow of illegal drugs and migrants entering the U.S. before imposing tariffs or closing the southern border.

But the threats and the slowdown of border crossings have already had a negative impact on residents, business people and advocates working with immigrants.

"It’s causing stress because you don’t know what’s going to happen," said one El Paso resident.

'I am afraid of being discovered — then I would be killed'

Those were the whispered words of Fadi, a 23-year-old in Baghdad. He does not believe in God, and he is terrified.

After the Islamic State conquered huge swaths of Iraqi territory and enslaved, raped and killed thousands in the name of God, some are turning away from religion.

But many atheists in Iraq have been forced underground as religious hard-liners battle for control of the young democracy, which is struggling to balance the demands of both Sunnis and Shiites, plus smaller ethnic and religious communities.

He claimed he was a boy who vanished in 2011. His DNA said otherwise.

The person who turned up earlier in the week claiming to be Timmothy Pitzen — a boy who went missing at six years old in 2011 — is not him after all.

He is actually a 23-year-old who was recently released from jail after serving an 18-month sentence.

The Week in Pictures

In memoriam

Dan Robbins, the artist who created the first paint-by-numbers pictures and helped turn the kits into an American sensation during the 1950s, has died. He was 93.

He said his inspiration came from Leonardo da Vinci.

"I remembered hearing that Leonardo used numbered background patterns for his students and apprentices, and I decided to try something like that," Robbins said in 2004.

Although the kits were panned by some critics, he went on to sell millions of them.
