UPDATE: 2:45 p.m.

The families of victims of the Colorado theater shooting sat through emotional testimony Monday from police officers who tried to save the lives of the wounded.

One sergeant recalled during the hearing for suspected gunman James Holmes that he checked and did not find a pulse for the youngest victim, 6-year-old Veronica Moser-Sullivan.

Another who drove the wounded to the hospital said he had to stop one man worried about his 7-year-old daughter from jumping out of the moving patrol car.

A bearded Holmes didn't appear to show any emotion. One woman sat with her head buried in her hands during the testimony about Veronica.

Investigators say Holmes opened fire during the midnight showing of the latest Batman movie on July 20, killing 12 people and wounding dozens.

A police officer who arrested James Holmes after the Colorado movie theater massacre thought he was a fellow officer at first because of the man was wearing body armor.

The officer then realized Holmes wasn't since he wasn't running toward the theater.

The officer and a colleague testified at a preliminary hearing Monday that Holmes seemed detached and volunteered that his apartment had been booby trapped.

Prosecutors are laying out their case against the former neuroscience graduate student at the hearing.

Investigators say Holmes tossed two gas canisters and then opened fire during the midnight showing of the Batman movie "The Dark Knight Rises" on July 20, killing 12 people and wounding dozens.

The hearing is expected to last all week.
