"I'm honored to speak for my generation. I want to be a voice for all kids to let the world know that we love and respect our police officers," said Savannah Solis.
Savannah said she was devastated by the news of two officers that were killed in an ambush in New York last month.
"When the tragedy with Officer Ramos and Officer Liu happened she was watching on the TV and it really bothered her, really upset her, and she started asking a lot of questions wanting to do something," said Savannah's mother Debbie Solis.
What Savannah did is touching officers all over the country.
"My goal is to tell as many officers as I can that I love them and I am thankful for what they do every day for us," said Savannah.
"She may be small, but the words she has are pretty powerful," said Assistant Chief Jason Dusterhoft of the Austin Police Department.
Savannah hand-made 500 thank you cards for officers in Tyler, Dallas, Irving, Houston, Austin and more.
"I just want to say, 'Thank you for taking care of us every day. You are my hero,'" Savannah told the officers.
Saturday, she delivered the cards in person to the Austin Police Department.
"I think it's a hard time right now being a police officer and sometimes we don't hear it enough that there's people out there that want to make sure that we get home at night," said Dusterhoft.
Savannah's message warmed the hearts of Austin's finest.
"To my heroes I want to say, 'Don't stop. Please don't give up. Many do not care or appreciate the sacrifices that you make every day, but I do," said Savannah.
Austin police gave her something in return.
"I got a sticker, this hat, and a challenge coin," said Savannah.
The only thing Savannah asked for in exchange is a signature.
"She just wants to get as many autographs as possible because they're her heroes," said Debbie.
"They mean a lot to me," Savannah added.
Savannah said she hopes officers everywhere keep doing what they do best.
"Officers all across Texas, you matter to me. Officers in New York City, you matter to me. Officers all across America, you matter to me," said Savannah.
"Please keep taking care of us because I will always respect you, I will always honor you, and I will always pray that God keeps you safe," she added.
Savannah said she hopes to someday wear a police uniform of her own.
