Highlights: 3 things you need to know now

Authorities have officially identified Elliot Rodger, 22, as the suspect in Friday night's shootings near the University of California, Santa Barbara.

Seven people, including Rodger, were killed. Rodger apparently stabbed three men in his apartment before going on a drive-by shooting rampage in his BMW; three people were fatally shot on the streets of Isla Vista.

Rodger, who had written a 137-page manifesto and posted a threatening YouTube video, apparently shot himself at the end of the rampage.

Elliot Rodger, the suspect in Friday night's deadly rampage near the University of California, Santa Barbara, fatally stabbed three men in his apartment before beginning his drive-by shooting spree on the streets of Isla Vista, where he killed three more people and wounded several others before turning a gun on himself, officials said Saturday night.

As authorities continued to piece together a complex sequence of events, which included 12 crime scenes at 10 locations, they were also poring over a 137-page misogynistic manifesto apparently written by Rodger, along with a YouTube video in which he chillingly laid out his plans for revenge against the world and retribution against women who had shunned him.

And in an emotional statement on Saturday, the father of one of the victims blamed "irresponsible politicians and the NRA" for his son's death.

The suspect

At a news conference Saturday night, Santa Barbara County Sheriff Bill Brown provided new details on Rodger and his actions Friday.

Rodger, 22, was a student at Santa Barbara City College who lived in Isla Vista, known as a party area for students of nearby UC-Santa Barbara. His father, Peter Rodger, was an assistant director for one of the Hunger Games movies.

The police had crossed paths with Rodger three times before Friday. In one incident, he was involved in an altercation; in another, he accused a roommate of stealing three candles valued at $22.

The deputies "found him to be polite and courteous," Brown said, and "determined he did not meet the criteria for an involuntary mental health hold." Rodger told the deputies about troubles in his social life and said he would probably not return to school the following year.

The visit, less than a month before the killings, is sure to raise questions about whether officials should have done more in Rodger's case. But Brown called that type of visit routine and commonplace. "I'm not going to go back and play Monday-morning quarterback at this point," he said.

The sequence of events

Rodger didn't just engage in drive-by shootings Friday night. He first killed three people at his apartment and then tried to enter a sorority house, officials said. And he predicted the entire sequence in his manifesto and YouTube video.

"It appears that he murdered three victims within his residence prior to the shooting rampage," Brown said. "The three male victims had been repeatedly stabbed." Brown did not identify those victims.

Rodger's next known move was to head to the Alpha Phi sorority, where several members of the house reported hearing aggressive knocking for a couple of minutes. "Fortunately, no one opened the door," Brown said.

In his YouTube video, Rodger said he wanted to "enter the hottest sorority house of UCSB" and "slaughter every single spoiled stuck-up blonde slut I see inside there." Apparently stymied, he turned his gun on other students who were standing in the area.

He killed two UCSB students, identified as Katie Cooper, 22, and Veronika Weiss, 19. A third young woman suffered multiple gunshot wounds but survived.

Rodger then went to the I.V. Delimart, where he shot and killed Christopher Martinez, 20, bringing the death toll to six.

Rodger sped off in his black BMW, beginning a sequence of events in which he fired more rounds at multiple locations, wounding additional bystanders; engaged in two firefights with sheriff's deputies; struck two bicyclists; and finally crashed his car. In all, 13 additional people were injured, all civilians.

Of the seven victims still hospitalized, two are listed in good condition, three are listed in fair condition and two are listed as being in serious condition, according to Brown.

When the car finally came to a stop, deputies found Rodger "obviously dead with a gunshot wound to the head," Brown said. When asked if Rodger had been shot by police or shot himself, Brown responded: "It would appear that he took his own life."

Police recovered three 9-millimeter semiautomatic weapons along with dozens of loaded 10-round magazines from Rodger's vehicle. According to Brown, all three weapons had been legally purchased and registered.

Victim's father blames "irresponsible politicians and the NRA"

The father of Christopher Martinez, who was fatally shot by the suspect, delivered an emotional statement to the press outside the sheriff's office on Saturday.

"Our family has a message for every parent out there: You don’t think it will happen to your child until it does," Richard Martinez said.

He continued:

Chris was a really great kid. Ask anyone who knew him. His death has left our family lost and broken. Why did Chris die? Chris died because of craven, irresponsible politicians and the NRA. They talk about gun rights. What about Chris’s right to live? When will this insanity stop? When will enough people say, "Stop this madness"? We don't have to live like this. Too many have died. We should say to ourselves, "Not one more!"

Rodger wrote manifesto

Meanwhile on Saturday, a 137-page manifesto, apparently written by Rodger, made its way to the press.

#UPDATE: We've received a troubling manifesto from suspected shooter Elliot Rodger. Titled "My Twisted World" 140 pgs pic.twitter.com/Z0QxWkMYEA— Joe Buttitta (@KEYTNC3Joe) May 24, 2014

Titled "My Twisted World: The Story of Elliot Rodger," it documents Rodger's life and the events leading up to Friday's killings.

A sentence on the cover page of the document reads:

"This is the story of how I, Elliot Rodger, came to be. This is the story of my entire life. It is a dark story of sadness, anger, and hatred."

Mashable is reviewing the document; it has been published online in full.

The YouTube video

Even before authorities officially identified Rodger as the suspect, his last YouTube video had circulated widely on Saturday. YouTube took down the video, citing a violation of its guidelines, but it is still available elsewhere online:

In the recording, Elliot Rodger identifies himself and says the video will be his last. "Tomorrow is the day of retribution," he says. "The day in which I will have my revenge against humanity."

After grousing that "girls have never been attracted to me," Rodger threatens to kill members of a sorority house and then "take to the streets of Isla Vista and slay every single person I see there."

Lawyer for Rodger's father says parents had warned police

A lawyer for Rodger's father, Peter Rodger, delivered a short statement to the media on Saturday.

The lawyer, Alan Shifman, said that the younger Rodger "was being treated by multiple professionals" and had been diagnosed at an earlier age as "a highly functional Asperger's syndrome child." (In the wake of other shootings, experts have repeatedly noted that people with Asperger's are no more likely to commit crimes.)

Shifman said Rodger's parents had been aware of his YouTube videos "regarding suicide and the killing of people" and had warned the police about them. He said authorities had interviewed Rodger but determined he was "perfectly polite."

Statement from UCSB

The chancellor of UC-Santa Barbara released a letter to the community on Saturday.
