CENTENNIAL — Aurora police seized four prescription bottles and immunization records when they searched theater-shooting suspect James Holmes’ apartment in July, according to newly obtained filings in the murder case against Holmes.

The disclosures come in a back-and-forth between prosecutors and defense attorneys over whether those items should be subject to doctor-patient confidentiality. The judge ultimately ruled in October that prosecutors could keep the items.

Holmes is charged with 166 counts of murder, attempted murder and other offenses in the July 20 shooting rampage at an Aurora movie theater that left 12 dead and at least 58 injured.

The documents — many of which are heavily redacted — do not reveal what prescriptions the bottles were for or whether prosecutors intend to use them as evidence.

The documents simply add new droplets to the dribbled stream of information in the past several months about the theater shooting.

That stream, though, is expected to turn into a torrent starting Monday, when prosecutors begin laying out their case against Holmes in a critical hearing that will determine whether there is enough evidence for Holmes to face trial.

The proceeding — known jointly as a preliminary hearing and a “proof evident/presumption great” hearing — starts at 9 a.m. Monday in the Arapahoe County courthouse and is expected to last all week.

It is expected to be the first time detectives testify at length about the case and the first time prosecutors show pictures and video of the shooting scene.

The hearing may also be the first time Holmes’ attorneys are able to thoroughly challenge prosecution evidence and present their own version of the story.

By the end of the week, the public will likely know far more than it does now about the planning, execution and, perhaps, motive behind one of the worst mass shootings in U.S. history.

But experts say the outcome of the hearing is little in doubt.

“Prosecutors don’t lose preliminary hearings in Colorado,” said legal analyst and former prosecutor Craig Silverman. “It’s a minimal standard.”

Silverman said he expects prosecutors to lay out an extensive timeline of the July 20 shooting, describing how the shooter moved through the theater and switched from one weapon to the next.

Prosecutors will have to present evidence related to each of the victims — the 12 people killed and the 70 others who were wounded or shot at.

“There’s just so many victims, it could take a long time,” Silverman said.

Attorney Dan Recht, though, said the prosecution and the defense will have deeper motives than just presenting and challenging evidence.

“The issue in this case is going to be ultimately whether Holmes is sane or not sane,” Recht said. “This is not a whodunit case. … The preliminary hearing is going to focus on, to the extent the parties can, the sanity issue.”

Recht said prosecutors will likely try to present their evidence in a way that makes Holmes look like a calculated, clear-headed planner.

Defense attorneys, meanwhile, will likely raise questions about Holmes’ mental well-being.

That is why, Recht said, defense attorneys were insistent about being able to call two witnesses who can speak to Holmes’ “mental state,” when the defense usually does not call witnesses at a preliminary hearing.

But Silverman noted there is little about this case that is usual. Preliminary hearings often last less than an hour.
