The home of the grandfather of Veronica Moser-Sullivan—the youngest Aurora, Colo., movie theater shooting victim—was burglarized on Tuesday, Denver police say. Among the items stolen were four cameras, including a digital camera with a memory card that the grandfather says had some of the last photos ever taken of the 6-year-old, who was among 12 people slain during the July 20 shooting.

"The pictures hold special significance," Robert Sullivan, Veronica's grandfather, told the Denver Post. "She was a beautiful, special little 6-year-old girl, so angelic, and just a terrible loss."

One of them, taken in May and later published in People magazine, showed Veronica enjoying an ice cream cone with her grandparents on the last day of school.

Ashley Moser, Veronica's 25-year-old mother, was shot in the neck and stomach and survived. But her family said she later suffered a miscarriage as a result of her injuries.

According to police, the burglary occurred Tuesday morning. Sullivan and his wife were not home at the time, and the thieves entered through a window.

Sullivan said he did not think the burglars intended to steal the photos of his granddaughter—just the cameras—and is asking that they return the memory card.

"I look at what happened here today, and it's just another spike in the heart," he said. "And my heart has been torn apart."
