Perkins says she drove by Santa Fe High School and saw the victims' crosses.
It really hit home.
She went home, started playing the piano and wrote a song.
Santa Fe HS graduate writes song in memory of shooting victims
"I just sat down and it was like an hour, and I just wrote the whole thing and I cried a lot when I wrote it," said Perkins.
Perkins graduated from Santa Fe High School two years ago. Her brother graduated a year after that. The school halls are still home and still part of her.
Part of the lyrics in the song say, "Between those walls, we've all walked a mile. We've sat in those chairs. We've been in there too."
Perkins says writing the song was therapeutic.
"When I think of Santa Fe, I think of family and I think of generosity and kindness everybody is just so willing, to throw everything down and be there for that other person," she said.
