There are two 10-year-old girls in the hospital, one in critical condition and the other in good health.
The hospital reported Thursday that a 9-year-old child is doing well.
According to a spokeswoman at Brooke Army Medical Center in San Antonio, two adult victims of the incident were being treated there, both in critical condition.
Officials stated the shooter was a Uvalde High School student.
A photo of two AR-15-style firearms came on an Instagram account linked to Ramos three days before the incident.
According to a former student who did not want to be recognized, Ramos recently shared a photo of an AR-15, a rucksack with rounds of ammo, and many weapons magazines to a former classmate.
