• Below are the latest updates as they come to us or you can read our story of the Connecticut school shooting

[Updated at 6:02 p.m. ET] "Evil visited this community today," Connecticut Gov. Dan Malloy just told reporters in Newtown. "And it's too early to speak of recovery, but each parent, each sibling, each member of the family has to understand that Connecticut - we're all in this together.

"We'll do whatever we can to overcome this event. We will get through it. But this is a terrible time for this community and these families."

[Updated at 5:14  p.m. ET] The mother of the suspected shooter was found dead in her son's residence in Newtown, a law enforcement source with detailed knowledge of the investigation told CNN. CNN had previously identified the mother as Nancy Lanza, a teacher at the Sandy Hook Elementary, according to law enforcement sources.

The source also told CNN there was no body found in the house searched by authorities in Hoboken, New Jersey. Two law enforcement sources say a man was taken away from questioning from that house. He is believed to be the brother of the shooter, according to the sources.

The first law enforcement source says the school shooter was dressed in "black battle fatigues and a military vest."

The Bushmaster .223 found at the scene is a semi automatic weapon, the source says. Two other weapons found were handguns, a Sig-Sauer and a Glock.

[Updated at 5:10  p.m. ET] We just learned that Governor Dannel P. Malloy will be speaking at Treadwell Park in Newtown, Connecticut, at 6:00 p.m. ET.

[Updated at 5:04  p.m. ET] We've just received a statement from U.S. Secretary of Education Arne Duncan about the shooting:

"School shootings are always incomprehensible and horrific tragedies. But words fail to describe today's heartbreaking and savage attack at Sandy Hook Elementary School. As the father of two children in elementary school, I can barely imagine the anguish and losses suffered today by the Newtown community.

"Our hearts and prayers go out to every parent, child, teacher, staff member, and administrator at Sandy Hook and the surrounding community. And our thanks go out to every teacher, staff member, and first responder who cared for, comforted, and protected children from harm, often at risk to themselves. We will do everything in our power to assist and support the healing and recovery of Newtown."

[Updated at 5:01  p.m. ET] Law enforcement officials are not prepared to identify the shooter right now, Connecticut State PoliceLt. J. Paul Vance said in a press conference.

Vance said that they are working diligently at the crime scene as well as with the medical examiner to identify the victims.

"We will leave no stone unturned," Vance added about the entire investigation.

[Updated at 4:54 p.m. ET] We are now being told there was no body found in the Hoboken, New Jersey, home as had been previously reported.

[Updated at 4:23 p.m. ET] We have learned that Connecticut police have searched the suspected gunman's home and place of employment in the wake of Friday's mass shooting, Connecticut State Police Lt. Paul Vance told CNN's Wolf Blitzer.

They have also interviewed his friends, relatives and "everyone who possibly had any connection with him whatsoever," he said.

[Updated at 4:11 p.m. ET] Police did not discharge their weapons at any time when responding at the school, police spokesman Lt. Paul Vance told CNN's Wolf Blitzer. However, he could not confirm whether the suspected shooter - who died at the scene - killed himself, saying that would have to be determined by the medical examiner.

[Updated at 4:07 p.m. ET] Mark Kelly, who's lived through this kind of horror, has issued a statement. He's the husband of former Congresswoman Gabby Giffords who was shot in the head at a massacre in Tucson, Arizona, in January 2011. Here's what he said:

I just woke up in my hotel room in Beijing, China, to learn that another mass shooting has taken place - this time at the Sandy Hook Elementary School in Connecticut. My thoughts and prayers are with the families of the victims and the entire community of Newtown, CT. I just spoke to Gabby, and she sends her prayers from Tucson.

As we mourn, we must sound a call for our leaders to stand up and do what is right. This time our response must consist of more than regret, sorrow, and condolence. The children of Sandy Hook Elementary School and all victims of gun violence deserve leaders who have the courage to participate in a meaningful discussion about our gun laws - and how they can be reformed and better enforced to prevent gun violence and death in America. This can no longer wait.

[Updated at 3:56 p.m. ET] The principal killed was Dawn Hochsprung. We received this photo via Newtown.Patch.com.

[Updated at 3:54 p.m. ET] Three guns were found at the scene, CNN's Susan Candiotti reports. According to a law enforcement source, the third weapon found on the scene was a .223 Bushmaster. The other weapons, previously reported, are a Glock, and a Sig-Sauer. No word on the models of Glock or Sig-Sauer.

[Updated at 3:51 p.m. ET] A federal law enforcement source tells CNN's John King the information from the scene is that the shooter arrived and headed directly toward and to his mother’s classroom. That and the other information now emerging - another family member killed, police interviews - lead them to believe his mother was the primary target. But they note he also came armed with clear intention of mass killing.

[Updated at 3:45 p.m. ET] There were a total of 27 people dead at the school, Lt. Paul Vance of the Connecticut State Police said.

Six adults, 20 children and the shooter were killed. Eighteen students were pronounced dead at the scene, and two others died at the hospital, said Lt. Paul Vance of the Connecticut State Police. The six adults died at the scene.

[Updated at 3:43 p.m. ET] Connecticut State Police Lt. Paul Vance has just said that the shooting took place in one section of the school and in two rooms.

[Updated at 3:33 p.m. ET] Connecticut Gov. Dannel Malloy called the mass shooting "a tragedy of unspeakable terms."

"Earlier today a tragedy of unspeakable terms played itself out in this community," Malloy said, adding that "you can never be prepared for this kind of incident.

"A number of our citizens, beautiful children, had their life taken away from them as well as adults whose responsibility it was to educate and supervise those children," Malloy said.

[Updated at 3:22 p.m. ET] It appears that another member of the alleged shooter's family is dead. A senior law enforcement official familiar with the investigation says a brother of the alleged shooter was found dead in a home searched in Hoboken, New Jersey. We already knew the suspect's mother was found dead in the elementary school.

[Updated at 3:16 p.m. ET] From the president: "I offered Gov. Malloy my condolences on behalf of the nation."

The president appears to be emotional, he's wiping his eye.

Here's more of what he's saying:

"We've endured too many of these tragedies in the past few years. Each time I learn the news I react not as a president but as anybody else would as a parent.

"That was especially true today.

"I know there's not a parent in America that doesn't feel the same overwhelming grief that I do.

"The majority of those who died today were children, beautiful little kids between the ages of 5 and 10 years old.

"They had their entire lives ahead of them, birthdays, graduations, weddings, kids of their own.

Obama sighed.

"Among the fallen were also teachers - men and women who devoted their lives to helping our children fulfill their dreams. Our hearts are broken today for the parents and grandparents, sisters and brothers of these children and the families of the adults we lost.

"Our hearts are broken for the parents of the survivors as well, for as blessed as they are to have their children home tonight, they know that their children’s innocence has been torn away from them too early, and there are no words that will ease their pain.

"As a country, we have been through this too many times. Whether it’s an elementary school in Newtown, or a shopping mall in Oregon, or a temple in Wisconsin, or a movie theater in Aurora, or a street corner in Chicago - these neighborhoods are our neighborhoods, and these children are our children. And we're going to have to come together and take meaningful action to prevent more tragedies like this, regardless of the politics.

"This evening Michelle and I will do whah every parent in America will do - hug our children a little tighter and tell them that we love them.

"There are families in Connecticut that cannot do that tonight and they need all of us tonight.

"May god bless the memory of the victims and in the words of scripture heal the broken hearted and bind up their wounds."

Eventually police came in and let her daughter and her teacher leave the school building.

"I'm even kind of numb about what's going on," she told CNN's Wolf Blitzer. "I'm in a state of shock. I don't know how Im going to handle having [my daughter] know ... about the whole situation."

[Updated at 1:57 p.m. ET]  The death toll is closer to 30 than 20, a federal law enforcement source in Washington told CNN's John King.  Most of those killed are children, the source said.

[Updated at 12:59 p.m. ET] Many people are talking again about gun control. But White House spokesman Jay Carney isn't joining in for now.

"I think it's important on a day like today to view this as I know the president, as a father does and I as a father and others who are parents certainly do, which is to feel enormous sympathy for families that are affected and to do everything we can to support state and local law enforcement and support those who are enduring what appears to be a very tragic event.  There is, I'm sure, will be, rather, a day for discussion of the usual Washington policy debates but I don't think today is that day.
