LAS VEGAS -- Days before 12-year-old Austin Mercado died, on Jan. 27, 2012, the sixth grader began vomiting at Johnson Middle School and went to the nurse.
Three days later, Austin had to be escorted by a teacher back to the school nurse because he was still suffering from severe stomach pain and had a fever of 100.9 Fahrenheit.
By Feb. 3, the day before he died, the nurse said he was "dehydrated, weak, pale and his fingers were blue."
"The school could have do more," Austin's stepmother, Kalinda Mercado, said. Mercado is facing a charge of murder in the boy's death.
Speaking outside the courtroom, Mercado said the school should have called 911.
