The Newsroom's timeline, which trails along just behind the present day, has finally caught up with last year's Boston Marathon bombing. In the season premiere, Will McAvoy and friends turned their Sorkin-given powers of razor-sharp righteousness toward Reddit's botched online hunt for the bombers.

A year after two bombs hidden inside backpacks exploded at the Boston Marathon, police again were forced to evacuate the finish line area to investigate two suspicious backpacks, at least one of which was deposited by a man in a veil yelling "Boston strong."

One year ago today, one minute after two bombs exploded near the finish line of the Boston Marathon, a journalism student named Dan Lampariello uploaded to his Twitter account a photo of the blast, taken from his vantage point a few blocks down Boylston Street.

With the 19-year-old suspect in the Boston Marathon bombings finally awake and apparently answering questions, authorities are eager to see if their suspicion that he and his older brother were planning on hitting targets beyond Boston will be confirmed.

Four days after he and his older brother, Tamerlan, allegedly bombed the Boston Marathon, killing three and injuring dozens more, 19-year-old Dzhokar Tsarnaev is finally in custody. The days-long manhunt ended as bizarrely and gruesomely as it started: with Dzhokar trapped on a boat in a Watertown, Massachusetts, backyard, covered in blood—possibly his own—and surrounded by police. After a lengthy standoff and a conversation with a negotiator, Dzhokar turned himself over to the authorities.

As America and the rest of the world continues to mourn the loss of those who died as a result of Monday's bombings at the Boston Marathon and the ongoing efforts to bring the suspects to justice, it's important to remember that, for many of the living victims, the nightmare is far from over.

A Republican lawmaker from Arkansas upset both Bostonians and non-Bostonians from both sides of the aisle this morning after he felt the need to tweet a pro-gun message around the time two armed police officers were being shot in their pursuit of the Boston Marathon bombing suspects.

After spending the better part of last night dragging Sunil Tripathi's name through the mud and negligently inflicting emotional distress on his friends and family, Reddit now wants to play a part in helping find the missing Brown student.

The city of Boston has been asked to shelter in place as police hunt for a suspect in the Boston Marathon bombings. Dzhokhar Tsarnaev, 19, and his brother Tamerlan, 26, both suspects in the attack, allegedly engaged in a shootout with police in Watertown, Mass. last night; Tamerlan was killed and Dzhokhar fled.

The FBI released photo and video this afternoon of two suspects in Monday's Boston Marathon bombing, and is asking the public's help in identifying them. They're calling them "Suspect One" (dark hat) and "Suspect Two" (white hat), and believe them to be associated. You can see photos of them here, or on the FBI's site.

This is what has been happening on cable news for the past few hours: After insisting that they had confirmation from two separate sources that an arrest had been made in the marathon bombing, and while ignoring reports from nearly every other source that said otherwise, CNN was forced to admit that there were then three sources telling them that no arrest had been made and just recently changed their report status to "conflicted." Meanwhile, there were several different descriptions of the "suspect" that was never identified in the first place in is not at all in custody but might be for all we know.

After viewing security-camera footage from the surrounding area, investigators have identified a "possible suspect" in the Boston Marathon bombings, several outlets are now reporting.

Here's what investigators have said they know, so far, about the Boston Marathon bombings that killed three and injured 183 people on Monday: The explosive devices used were built out of conventional pressure cookers placed in nylon backpacks. What they don't know: anything else. The "range of suspects and motives remains wide open [...] Someone knows who did this," Special Agent Richard DesLauriers, the lead investigator, told reporters. "[T]he person who did this is someone's friend, neighbor, coworker or relative." The Bureau is actively soliciting photographs, tips and information; examining the bombs; and using face-recognition software in an attempt to generate leads. No one has claimed responsibility, and the "Saudi national" briefly placed in custody after the bombing (whose suspecthood was loudly touted by the New York Post and Fox) is no longer a person of interest. It will be a "long, painstaking investigation," Massachusetts Governor Deval Patrick told WBUR this morning, but "every hour, every day" will get us "a little closer."

On Tuesday, the Associated Press and Fox 5 in Atlanta obtained photos from an FBI intelligence bulletin showing what's left of one of the bombs that exploded during the Boston marathon. As earlier reported, at least one of the bombs used in the attack was improvised from a conventional pressure-cooker.

Thousands of Boston Marathon runners were still making their way to the finish line when the bombs went off yesterday afternoon.

What do you do with your instantly publishing short-form social-media account when something big has happened but you don't know exactly what? Correct answer: nothing. But in the absence of reliable information yesterday, reflexive Twitter users filled the time by emptying out the preexisting contents of their heads.

"Anytime bombs are used to terrorize innocent civilians, it is an act of terror," President Obama clarified, citing a definition of terrorism. Now that that's cleared up, we can talk about the fact that we still know nothing about the bombing. The President went on to say:

Yesterday, two bombs detonated at the finish line of the Boston Marathon, killing three and injuring more than 100 people. Here's everything we know about the bombing, its aftermath, and the hunt for the culprits.
