Connecticut State Policeman J. Paul Vance stated that an announcement regarding the motivation behind Friday's tragic Sandy Hook Elementary School shooting in Connecticut won't likely come anytime soon.  The Lieutenant said that investigators wouldn't issue an official timeline of events while the investigation was still being conducted.

Vance had spoken at a news conference in Newtown, Connecticut early Sunday morning and stressed that police were working with each other in order to piece the evidence together, according to the Chicago Tribune.

In tribute to the those lost, President Barack Obama is scheduled to attend an interfaith memorial service in Newtown on Sunday evening.  The President's visit to Connecticut for the Sandy Hook vigil will be the fourth time he's had to travel to a city for a mass shooting-related incident.

During the horrific event there were many heroes among the victims.  The acts of bravery ranged from a school worker alerting others via intercom that something was wrong to a custodian putting his life at risk running through the halls shouting "Guys, Get down!  Hide!"

"The teachers were really, really focused on their students," District Superintendent Janet Robinson stated to the publication.  She also said that their "incredible acts of heroism" in what "ultimately saved so many lives."

Upon gunman Adam Lanza entering through the building door, school psychologist Mary Sherlach and principal Dawn Hochsprung immediately ran to him, according to Robinson.  Hochsprung was killed while lunging at Lanza and Sherlach was gunned down as well.

Just in October, Hochsprung had taken to Twitter to post a picture of the school's evacuation drill with the title "Safety first."

Sherlach, 56, would've had the task of assisting the survivors of the horrific ordeal, but died doing what she loved the most, her son-in-law Eric Schwartz said.

"Mary felt she was doing God's work, working with the children."

During the tragedy, twenty-six people, which included 20 children, were gunned down when Lanza opened fire inside the school on Dec. 14.
