Weeping through closed eyes, Ian Sullivan listened Tuesday to a 911 call that detailed the death of his 6-year-old daughter, Veronica, in a Colorado movie theater.

The 4-minute recording captured the voices of two people: a 911 dispatcher and a crying 13-year-old desperately trying to get help for her little cousin and for Veronica's gravely wounded mother, Ashley Moser.

"Who's been shot?" the dispatcher asked.

"My two cousins," the young caller said. "On the floor ... not breathing."

The 911 operator told her she had to perform CPR, but it was too loud in Theater No. 9 -- the movie still playing, screams filling the air -- for her to follow the instructions.

"Help me!" the girl shouted a few times.

Ashley Moser, 25, shot in the stomach and neck, survived but suffered a miscarriage and was paralyzed. Her daughter could not be saved.

Veronica was the youngest of the 12 people killed at the Century 16 theater when James Holmes allegedly opened fire during a midnight screening of the Batman movie "The Dark Knight Rises." 

The 911 call was played during a preliminary hearing in which prosecutors are laying out their case to convince a judge there's enough evidence to put Holmes on trial for first-degree murder.

Victims relatives have been in the courtroom and overflow rooms, reacting with anguish at times during hours of emotional and sometimes graphic testimony.

During Tuesday's proceedings, prosecutors played a second 911 call. It was barely half a minute long, but the sound of 33 gunshots could be heard.

The caller, Kevin Quinonez, struggled to be heard but managed to convey some sense of the inexplicable horror unfolding around him: "There's some guy after us."

Flags flew at half-staff across Colorado on Tuesday as mourners gathered at a Denver church to pay tribute to the youngest victim of the Aurora theater massacre.

Services for 6-year-old Veronica Moser-Sullivan were being held at the Church of the Risen Christ in Denver, followed by a private funeral for the family, according to local media reports.

Veronica was one of 12 people killed in the July 20 shooting at an Aurora movie theater showing the latest Batman movie, “The Dark Knight Rises."

Her mother, Ashley Moser, was among dozens of theater-goers wounded. She was shot several times and left paralyzed, and also miscarried a pregnancy as a result. She remains at a local rehabilitation center.

Funeral plans for Veronica were delayed while Moser underwent rehab.

James Holmes, 24, a former Ph.D. neuroscience student, is accused of being the theater shooter.

Gov. John Hickenlooper ordered flags be lowered to half-staff on Tuesday in memory of Veronica.

Flags were lowered in the days after the shooting in memory of those killed in the theater and raised again July 29 after the last scheduled funeral. The governor announced at the time he would lower flags again when the funeral for Veronica was set.

The family recently suffered another tragedy when someone stole a camera with the last photos taken of Veronica. The girl’s grandfather, Robert Sullivan, has said burglars broke into his west Denver home earlier this month and stole money, jewelry and cameras, including one with a memory card with photographs of his slain granddaughter.

Nearly $5 million raised for the victims of the theater massacre will be distributed next month. The bulk of the money will go to the families of the 12 people who died and to those most gravely wounded.

Separately, a website has been set up to accept donations for Ashley Moser.
