CENTENNIAL, Colo. 鈥 James Holmes had July 20, 2012 circled on the calendar hanging from a wall in his apartment. He drew an infinity sign around the date. Perhaps it meant he could never turn back. Perhaps it meant after the act, he would only infinitely move forward in a single direction.

There will be no turning back once the jury decides the defendant鈥檚 fate. He stands trial for shooting and killing 12 and injuring 70 at the midnight premier of 鈥淭he Dark Knight Rises鈥 on July 20, 2012. Defense attorneys seek to prove Holmes was insane on that night. Prosecutors seek the death penalty.

Monday, Day 10 of the trial, was a battle between the defense and prosecution on technicalities, each side fighting for any inch to be gained. The fight dragged out.

Antsy jurors fanned themselves with stacks of paper or fidgeted in their chairs. They were, however, engaged, Judge Carlos Samour said.

鈥淭he jury has a lot of questions, so feel free to mingle, just not about the case,鈥 he said.

The jury asked several questions about the evidence collected from inside James Holmes鈥 apartment. It was rigged to explode upon the trigger of a trip wire. The jury honed in, asking about the intricate design鈥檚 intentionality, including: What was the design set up to accomplish? Were the explosives set up for functionality or intimidation?

The jury probed the witnesses to determine whether testimony supported the defense鈥檚 position on intimidation or the prosecution鈥檚 position on functionality.

Prosecution called FBI Special Agent Christopher Rigopoulos to the stand. He described in detail what the FBI found in JH鈥檚 apartment.

Commercially available explosives were rigged to blow and gasoline saturated the carpet fibers,聽Rigopoulos said. With the use of a robot and controlled movements, the FBI entered without incident. 鈥淒istractors鈥 were in place to divert attention away from the explosives, including a blinking LED light, Rigopoulos said.

鈥淚t鈥檚 not part of an I.E.D., it鈥檚 an enhancement,鈥 Rigopoulos said of the light.

Rigopoulos used the term 鈥渄esign鈥 several times throughout his testimony. The insistence suggested he thought the process took forethought and focus.

The defense objected to several parts of Rigopoulos鈥檚 testimony as there was speculation. It seemed he was characterizing the set up as intentional, intricate and almost militaristic.

The defense created a space for their argument amid another daunting pile of evidence when it asked Rigopoulos to confirm that pharmacy paperwork was collected at the apartment. The exhibits were not published and the specific medications were not identified at that time. The defense will likely return to the exhibits.

鈥淚t would have functioned as designed,鈥 Rigopoulos said.

Jessica Cummiskey holds a postdoctoral position at the 麻豆影院 doing research on molecular, cellular and developmental biology. She worked in the same lab as Holmes during his time as a Ph.D. student in 麻豆影院.

Holmes seemed to almost stare though the desk during class, Cummiskey said. It didn鈥檛 seem to her that he was engaged or ever paid attention. She can鈥檛 recall him taking notes or having a book open during discussions.

鈥淗e would snap back into it and answer the question correctly,鈥 Cummiskey said of Holmes when professors called on him.

She noticed his pupils were completely blown out a handful of times, Cummiskey said. She described them as shocking, stunning.

She attempted to engage Holmes in small talk but he wasn鈥檛 receptive. He even went out of his way to avoid interaction with her, Cummiskey said.

鈥淎fter a while I just stopped any sort of communication,鈥 Cummiskey said.

Two witnesses were called to testify on invoices found for the purchase of armor.

The jury asked no questions about the invoices, despite the exorbitant amount of time spent debating whether the evidence was admissible.

The invoices, however, revealed that on armored chaps and a gas mask alone, the defendant spent approximately $1,000, months before the date of the attack.
