What lies ahead in the investigation into the Orlando shooting

Fifty people are dead and another 53 people are injured after a shooting at a gay nightclub in Orlando in what now ranks as the deadliest attack on American soil since 9/11.

The suspect has been identified as a 29-year-old American-born man of Afghan descent named Omar Saddiqui Mateen. He was killed in a shootout with an Orlando police SWAT team early this morning that apparently saved 30 hostages. You can read more on the facts of the case so far here.

With the shooter dead, the investigation into the incident will focus on establishing his motive for the attack, and the degree to which he may have been influenced by radical views.

A key step will be rounding up computers, phones and other devices he used, and analyzing any statements he might have made on social media or in web forums.

When investigating the shooting in San Bernardino, Calif., last year, FBI agents found that one of the shooters had posted and then deleted a message of allegiance to the leader of the Islamic terrorist group known as ISIS. Given this shooter’s heritage, the FBI will be looking for similar signs.

Depending on what devices are recovered during the investigation, we may see a replay of last year’s legal confrontation between the U.S. Department of Justice and the tech industry over encryption.

Recall that one of the shooters in San Bernardino used an iPhone 5s. In an effort to tie up all the threads in their investigation, the FBI took Apple to court, hoping to force the tech giant to open up the phone. Apple refused. The government dropped its case after it got help elsewhere.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
