A fourth-grade student attempted to call 911 during the Texas mass shooting that claimed the lives of 19 children and two adults this week.

Ten-year-old Amerie Jo Garza, who attended Robb Elementary School in Uvalde, Texas, tried to call 911 on her cellphone before the 18-year-old gunman killed her.

Ameries grandmother, 49-year-old Berlinda Arreola, told The Daily Beast that the 10-year-old had her cellphone when the gunman entered the classroom. Arreola, who also spoke to People , called her granddaughter a hero.

U.S. Marshals told Ameries father, Angel Garza, about his daughters death, according to KABC-TV .

Thank you everyone for the prayers and help trying to find my baby, Garza told KABC-TV. Shes been found. My little love is now flying high with the angels above. Please dont take a second for granted. Hug your family. Tell them you love them. I love you Amerie jo. Watch over your baby brother for me.

Amerie had just celebrated her birthday on May 10, Garza told the news station.

A Facebook page identified as Garzas page recently posted a link to a GoFundMe campaign to help with his daughters funeral costs.

For anyone asking, Im sorry we have been trying to stay away from all media in a time like this, Garza said. I love you guys so much for getting my babies name out there. She was my hero.

According to People, Amerie had a loving bond with her 3-year-old brother Zayne and always kissed him before leaving for school every morning.
