Daughter Writes Song to Remember Father Killed in Line of Duty

It was a somber celebration for one Atlanta family. Friday marked the 42nd birthday for fallen Atlanta Police Officer Mark Cross.

Officer Cross was killed in the line of duty just over 10 years ago during a traffic stop after a suspect opened fire on him.

His daughter, Aida Jazzmin, wrote the song with the help of her music teachers 2 years ago. She said she was inspired by her late father and stories that her family tells her about her father.

In her Facebook post, Aida left the heartfelt, personal message.

Happy Birthday Daddy. I wish you were here and celebrate with us on this special day. I know you are watching over us always. I love you very much. This is a song from me to you. I recorded almost 2 year ago and I have you as my inspiration. The teachers at my music school wrote and arranged this song beautifully just for you and I. Every words in this song meant a lot to me. Mama cried the first time she heard the song. I can remembered you very little of it but Thanks to Thai Chaiboon Cross and Mama. They kept telling me of all the story about you until I felt my present. Daddy, Happy Birthday and I love you. I hope I get to know you more and be together again one day. Other than that! ENJOY YOUR SONG!!!

"Daddy, Happy Birthday and I love you. I hope I get to know you more and be together again one day," she wrote.

Officer Cross was a 6-year veteran of the Atlanta Police Department. He was just 31 when he passed.
