Friends, relatives and even parents reached out online trying to find their missing loved ones.
Family members have confirmed the names of six students and a teacher's aide killed Friday when a student opened fire on his peers at Santa Fe High School.
In all, 10 people were killed and 10 were injured in the shooting that occurred between 7:30 and 7:45 a.m. Friday.
Santa Fe students Aaron Kyle McLeod, Angelique Ramirez, Chris Stone, Jared Conard Black, Kimberly Jessica Vaughan, Shana Fisher, Christian Garcia and Sabika Sheikh are confirmed dead, along with art room teacher's aide Cynthia Tisdale, according to their families.
The daughter of Ann Perkins confirmed that her mother died during the tragic shooting.
A GoFundMe account has been set for Perkins and all of the victims.

Casidy Welch was working at the gym when she heard about the shooting. She saw the confusion many people had trying to track down survivors and victims.
She created a list that was widely shared, a rundown of those missing.
Welch said she couldn't sit by and do nothing. Sadly, one by one, she removed names from the missing column and added them to a list of the dead.
"This is such a tragedy. I don't know, these names will be engraved and embedded in me forever," Welch said. "And I hope these families find some kind of peace."
Tisdale's husband told Eyewitness News Friday evening that "he killed her. She's gone," referring to student Dimitrios Pagourtzis, who was detained by police after the shooting.
Tisdale's niece, Leia Olinde, said Tisdale was like a mother to her and helped her shop for wedding dresses last year.
"She helped me put it on, she helped fix my hair," Olinde said through tears.
Sheikh was a Pakistani foreign exchange student who was due to go back home to Pakistan for Eid al-Fitr, a three-day holiday that marks the end of the holy Muslim month of Ramadan.
Megan Lysaght, manager of the Kennedy-Lugar Youth Exchange & Study Abroad program (YES), sent a letter to students in the program confirming that Sabika was killed in the shooting.
"Please know that the YES program is devastated by this loss and we will remember Sabika and her families in our thoughts and prayers," Lysaght wrote.
Rangers were tasked with the heartbreaking duty of informing the families their loved ones have died in this tragedy.
The Galveston County Medical Examiner's Office says all 10 of the victim's bodies have been moved from the school to the county morgue. Officials asked family members of the victims not to come to the morgue, and that autopsies will not be conducted until Saturday.
