(CNN)Emotions are still raw, in Orlando and throughout the nation, as America copes with the aftermath of the deadliest mass shooting in its history. Here's the latest on the investigation, the reaction and more on those who lost their lives.

1. The latest

    The names of all 49 victims have now been released, and we are learning more about the people whose lives were cut short inside the Pulse nightclub. Investigators say shooter Omar Mateen actively searched for jihadist propaganda, like ISIS beheading videos. The gunman's father told CNN's Don Lemon that his son carried out "an act of terror," but wasn't sure if he was a terrorist. President Obama will go to Orlando on Thursday to honor the victims.

    2. The investigation

    Omar Mateen was a regular at Pulse, the gay Orlando nightclub where he killed 49 people, despite the fact he frequently spewed anti-gay remarks to coworkers. This conflicting portrait is a big part of the investigation into the massacre. A performer at the club estimates Mateen visited Pulse twice a month for about three years. And FBI Director James Comey said Mateen was the subject of a failed FBI sting operation.

    3. The victims

    So young, and so full of life. The 49 victims ranged in age from 18 to 50. Edward Sotomayor was a popular travel planner known as "top hat Eddie." Student Cory Connell wanted to be a firefighter. Accountant Eddie Justice -- who exchanged anguished text messages with his mom while he hid in a bathroom -- loved living downtown. The youngest victim, Akyra Murray, had just graduated high school. A fuller portrait of all of them is just now emerging.

    4. The tributes

    Vigils, blood drives, fundraisers. People around the world are honoring the victims with an outpouring of love and kindness. More than 5,300 donated blood Sunday in Orlando -- a single-day record. Volunteers handed out water to police. Equality Florida's GoFundMe campaign raised more than $1 million. And Anderson Cooper gave an emotional, seven-minute tribute, reading each victim's name and sharing something about them.

    5. The political reaction

    Politics, of course, intruded upon the grief, in the form of dueling speeches by the presumptive 2016 presidential nominees. The differences in tone and substance couldn't be more striking: Donald Trump was fiery as he not only doubled down on his Muslim ban proposal but expanded it to include nations with a history of terrorism. Hillary Clinton's laid out her plans for defeating ISIS, which include making the stopping of "lone wolves" a top priority.
