AURORA, CO (NEWS1130) – The Aurora, Colorado, police chief says the suspect in the movie theatre shooting set up booby traps in his apartment specifically to kill a police officer who might have opened the door.

Chief Dan Oates says “we sure as hell are angry” at that.

At a Saturday news conference, he also tried to head off a mental incompetence defence by saying suspect James Holmes was deliberate and calculating in receiving numerous commercial deliveries to his home and workplace over the past four months. He says that explains all the ammunition Holmes had.

Oates says the major threat has been removed from the apartment, but an FBI agent says some dangers still remain, though families should be allowed back into their apartments by Sunday.

The suspect in yesterday’s massacre purchased four guns in the last two months, along with thousands of rounds of ammunition, according to police.

Police believe the guns were legally bought at local gun stores and online.

American President Barack Obama used his weekly radio address to reassure concerned citizens.

“This weekend I hope everyone takes some time for prayer and reflection, for the victims of this terrible tragedy, for the people who knew them and loved them, for those who are still struggling to recover,” Obama said.

Holmes is due to make his first appearance in court Monday, where he will face charges of murdering 12 people and wounding 59 others at a deadly movie theatre shooting in the Colorado suburb of Aurora. The theatre was showing the latest Batman movie “The Dark Knight Rises.”

The four weapons used in the massacre include an assault rifle, while Holmes was also wearing body armour and a gas mask.

The Ph.D student previously had no criminal record.

Police have not yet entered his apartment to search for clues, as they believe it is rigged with explosives.

“It is a very vexing problem how to enter that apartment safely, I see a lot of wires, trip wires, jars full of ammunition, jars full of liquid,” says police.

Hundreds of residents have been evacuated from five apartment buildings in the area, including the one where Holmes lived.

Justin Davis, who was sitting in the theatre next to where Holmes allegedly opened fire, saw bullets rip through the walls. He says he hopes the community can find a way to move on.

“We should just forgive and we don’t know what he’s going through, you don’t know why he did it, we don’t know what was going on his life to make him do this,” Davis said.

Bomb disposal experts hope to get into Holmes’ apartment sometime this weekend.

No information indicating plans for more shooting sprees

The FBI and Homeland Security Department say there is no information indicating plans for more shooting sprees at movie theatres around the country.

According to an intelligence bulletin obtained by The Associated Press, investigators have not figured out the suspected shooter’s motivations.

Security at some movie theatres around the United States has been increased after the deadly attack in Colorado. Some events around the world for the premiere of the new Batman movie have been cancelled or scaled back.

News1130′s Adam Forsythe knew one of the victims, a sportswriter named Jessica Redfield

“I was going through Twitter when I was going to bed. She’s a sports journalist trying to break into the industry, writing for website called Busted Coverage,” explains Adam.

“They tweeted ‘NO! NO! NO! Our friend @JessicaRedfield, real name Jessica Ghawi was killed in that theatre. She wrote for BC.’ The name immediately stuck out to me and I clicked on her link. Her last six tweets were about how excited she was the movie was starting,” he explains.

“A local Colorado news affiliate wrote an article that says they confirmed with her family that she was one of the people killed.”

Adam met Jessica in Boston during the Canucks-Bruins Stanley Cup series.

“I tweeted that I was going there and she happened to see that tweet. We met up and had a few drinks, grabbed some food, and I ended up spending a full evening with her,” he recalls.

“[She was an] amazing girl… really nice, really eager. At the time, she was working in San Antonio for the Dallas Stars’ farm team and she was trying to get a reporting job with a big team. She was ecstatic she got this position, working for the Colorado Avalanche. That’s why she moved to Colorado. I hadn’t spoken with her for six or seven months but we had, up until that point, communicated through Twitter quite a bit.”

In a chilling coincidence, Ghawi writes in her blog that she was also at the Eaton Centre shooting in Toronto in June.

“I was shown how fragile life was on Saturday. I saw the terror on bystanders’ faces. I saw the victims of a senseless crime,” she wrote on June 5th.

“I can’t get this odd feeling out of my chest. This empty, almost sickening feeling won’t go away. I noticed this feeling when I was in the Eaton Center in Toronto just seconds before someone opened fire in the food court. An odd feeling which led me to go outside and unknowingly out of harm‘s way. It’s hard for me to wrap my mind around how a weird feeling saved me from being in the middle of a deadly shooting” she added.

Moviegoers speak of their terror

Bejamin Fernandez, 30, has told the Post he heard a series of explosions. He says people ran from the theatre and there were gunshots as police shouted “Get down!” Fernandez says he saw people falling, including one young girl.

Jordan told the paper one girl was hit in cheek, others in the stomach, including a girl who looked to be around nine years old. He adds it sounded like firecrackers until someone ran into Theater 8 yelling “They’re shooting out here!”

Hayden Miller tells KUSA-TV that he heard several shots. “Like little explosions going on and shortly after that we heard people screaming.”

Hayden said at first he thought it was part of a louder movie next door. But then he saw “people hunched over leaving theatre.”

The youngest victim is a three-month-old baby, who is being treated in hospital. A six-year-old was taken to Children’s Hospital Colorado, where a total of six victims were taken.

Eleven people were being treated at the Medical Center of Aurora for gunshot sounds. Two others walked in to be treated for tear gas contamination. Denver Health took seven victims; two people were rushed to nearby Swedish Medical Center.

Aurora is on Denver’s east side and is Colorado’s third-largest city with 327,000 residents.
