Jaime Guttenberg has been described as an “awesome young girl” in a Facebook post by her cousin following the killings.
The family of one of the students killed during a mass shooting in Florida have paid tribute following the “senseless” killings.
Marc Pollack said his cousin Jaime Guttenberg, who attended Marjory Stoneman Douglas High School, was an “awesome young girl” in a Facebook post following the killings.
He wrote on Facebook: “This is a picture of our sweet cousin Jaime who was senselessly and tragically killed today at Stoneman Douglas High School.
“My heart is broken from the loss of this awesome young girl and the pain that our entire family is enduring.
“Jennifer Bloom Guttenberg, Fred Guttenberg and Jesse Guttenberg, we are all here for you. The love and strength in our family runs deep and you guys are not alone.
“Be strong for each other, hold each other up and keep Jaime in your hearts always and forever.”

A total of 17 people are confirmed to have died and more than a dozen are injured after the attacker opened fire at the school on Wednesday afternoon.
Another cousin of Miss Guttenberg, Laurie Singer Matthias, wrote on Facebook that she was “beyond grief stricken” and “beyond heartbroken”.
She added: “This beautiful young lady simply went to school today. And now her parents and our family are grieving, my precious cousins lives all our lives have been changed forever.
“RIP Jaime Guttenberg. Shine your beautiful light from the heavens for us to make our way through these very dark times.”
Football coach Aaron Feis was among those who died trying to save students after he reportedly used his body as a shield against the bullets.
The man has been hailed a hero after he tried to stop Nikolas Cruz killing youngsters at the school in Parkland.
One student, who called herself Angelica Losada, posted a picture of the coach with a baby, adding: “This, ladies and gentlemen, (is) the face of a hero.
“Coach Aaron Feis was injured protecting a student in the shooting at Marjory Stoneman Douglas High School and, at last report, is in critical condition.
“He is a friend to all students that know him. He was always so nice to me when I went to school there, and I know he is close with my brother and his friends.”
Despite initial reports suggesting he was in a critical condition, he was later believed to have died in hospital.
Broward Sheriff Scott Israel announced in a briefing at 9pm local time that “a beloved football coach is dead”.
