Ian Sullivan invited 9NEWS to his home in Denver to talk about Veronica's life.
Ian had a message to the families of survivors. He says they need to stay strong for their loved ones to help them recover quickly.
Ian says Veronica's mother, Ashley Moser, has been upgraded from critical to stable condition. Ashley was shot in the neck and stomach and had a bullet lodged in her throat.
She was told about Veronica's death this weekend, with a chaplain by her side. Ashley's aunt says Veronica loved school and had just started swimming lessons at a local recreation center.
