CENTENNIAL, Colo. — Prosecutors in the Colorado theater shooting trial rested Friday, concluding their argument that James Holmes methodically planned and executed the 2012 massacre in a case that relied heavily – over defense objections – on victims’ recollections of the carnage he inflicted inside the darkened cinema.

Over the past eight weeks, prosecutors weaved experts’ testimony with survivors’ personal stories to try to convince jurors that Holmes was sane when he opened fire on a midnight showing of the Batman film “The Dark Knight Rises.” The former neuroscience student killed 12 people and wounded 70.

For its last witness, the prosecution called a survivor whose story was among the most heart-wrenching.

Ashley Moser was paralyzed and suffered a miscarriage in the shooting, and her 6-year-old daughter, Veronica, was killed.

Moser came to the witness stand in a motorized wheelchair. She described hearing what she thought were kids setting off fireworks in the theater, and wanting to leave. She reached for her daughter’s hand, but it slipped away.

The soft-spoken Moser used a tissue to wipe away tears as she described the attack. She said it started with an explosion and something spewing gas behind her, then bright flashes at the front of the room. Moser said she assumed someone was setting off fireworks as a prank, and she stood up to take her daughter’s hand and leave.

“Did her hand reach back?” prosecutor George Brauchler asked.

“It just slipped through my hand,” she replied.

Moser said she felt a pain in her chest and fell on top of her daughter, but couldn’t move.

“I heard the movie still playing and people crying and screaming,” Moser said, vaguely recalling being carried out of the theater. She learned later that her daughter was dead.
