The witness statements were part of the Colorado Springs Police Department's official report into the December 2007 shootings at New Life Church.

A similar report from the Arvada Police Department detailing the shootings at the Youth With A Mission center is expected later this month.

The more than 450-page report includes diagrams detailing the gunman's path as well as statements from dozens of witnesses, law enforcement and survivors.

Although much of the information included in the report had been released in prior statements by Colorado Springs police, the report also included previously undisclosed details such as the discovery of five syringes that, at the time, contained a liquid unknown to police.

The report also describes how the gunman's parents confronted him when a box of bullets arrived, via mail, to their home as well as chilling statements from witnesses describing the gunman's demeanor as methodical.

CALL7 Investigators obtained a copy of the report and although it includes photographs of the crime scene, Colorado Springs police elected not to include graphic photos of the victims or the gunman, Matthew Murray.

The New Life Church was equipped with surveillance cameras, and although the report details activity on several cameras, none of the equipment captured Murray or any of the shooting.

According to the report, in the hours after the shootings, Colorado Springs police sent two detectives to Murray's home and discovered the filled syringes in his bedroom.

Initially, there was concern that the liquid in the syringes was a biochemical so they had to be seized by members of a Hazardous Materials team. Analysis of the liquid, by the Food and Drug Administration, determined it to be micro-toxin from an herbal substance that, if injected, would make a person violently ill but more than likely would not be deadly.

The report describes how, in late 2007, Murray's mother found a box in the mail addressed to Matthew and realized it was ammunition. According to a source, Murray's parents asked him about the ammunition and at the time they did not believe he owned any weapons. The source said Murray told his parents he purchased the ammunition for an upcoming hunting trip with a new group of friends.

Many witnesses described Murray's demeanor as emotionless, methodical, prepared and determined. One witness said Murray was holding his gun in a deliberate manner, pointing downward, as he slowly looked around, scanning. Others said Murray did not appear to be at all panicky.

According to the report, original calls to police detailed concerns of a second gunman and the potential for improvised explosive devices (IEDs) on the gunman's person and throughout the church property.

Police deployed a robot to remove a backpack from Murray's body, but while no explosives were found the report listed Murray as carrying a black semiautomatic pistol, a .40-caliber handgun, ammunition, an AR-15, and at least one smoke bomb.

7NEWS has also learned details of phone conversations Murray had with family members before and after the shootings in Arvada. A source told 7NEWS Murray called a cousin in Utah who later described the conversation as Murray "pouring his heart out." According to the source, the cousin described Murray as lonely, depressed, in crisis and needing to be hospitalized.

The source told 7NEWS, the cousin notified Murray's parents of his concerns and the parents talked to Murray, but they believed he was not in crisis. They did not know he had just returned from committing a double-homicide at Youth With A Mission.

The violence began about 12:30 a.m. Dec. 9, when Murray pulled a handgun and opened fire at the Youth With A Mission center after he had been denied a request to spend the night there. Witnesses told police that the gunman was a white man in his early 20s, wearing a dark jacket and skull cap and carrying a handgun.

More than 12 hours later, at New Life Church, Murray was wearing a trench coat and carrying a high-powered rifle when he opened fire in the parking lot. He then walked into the church as a service was letting out, Colorado Springs Police Chief Richard Myers said in December.

His department's report, released Wednesday, indicates at 1:10 p.m., 911 calls to Colorado Springs police identified an active gunman situation at the New Life Church. The investigation revealed that the gunman arrived at the church in his 1992 red Toyota, stopping in the southeast parking lot.

According to statements, included in Wednesday's report, some witnesses said they were able to get through to emergency operators while others reported their 911 calls were met with a busy signal.

Back in December, police said Murray tossed a smoke grenade at the north entrance of the church, just as Sunday service was ending, and then drove the short way to the east entrance to the church.

In the east entrance parking lot, he fired several rounds in the parking lot, hitting four people and multiple vehicles. Murray then walked into the building, went about 80 feet down the main hallway, firing at another man taking cover, and that's when he encountered security guard Jeanne Assam, police said.

Assam shot Murray several times and he put a gun to his own head and pulled the trigger, taking his own life.

The victims killed in the Colorado Springs shooting were identified as sisters Stephanie Works, 18, and Rachael Works, 16. Their father, David Works, 51, suffered two gunshot wounds -- one to the abdomen and one to the groin. They were shot in the parking lot as they were getting into their van.

The Works family had been with New Life Church for 1 1/2 years.

Judy Purcell, 40, was shot in the right shoulder and was treated and released. Larry Bourbannais, 59, was shot in the forearm and treated and released.

The two dead victims at the missionary center in Arvada were identified as Tiffany Johnson, 26, and Philip Crouse, 24. Johnson, who grew up in Chisholm, Minn., loved working with children and wanted to see the world, said family friend Carla Macynski.

"Tiffany was a well-liked, easygoing 26-year-old. She was friendly, adventurous and a definite leader. She wanted to see the world," Macynski said as she choked back tears. Johnson had traveled to Egypt, Libya and South Africa with the missionary group.

Crouse, of Alaska, had helped build a foster home at a Crow reservation in Montana, said Ronny Morris, who works with a Denver chapter of the mission.

Staffer Dan Griebenow, 24, of South Dakota, was shot in the neck, according to Youth With A Mission. Staffer Charlie Blanch, 22, suffered gunshot wounds to his legs, according to ministry officials.

Shortly after the shootings, Gov. Bill Ritter said, "Violent crimes of any sort are tragic enough, but when innocent people are killed in a religious facility or a place of worship, we must voice a collective sense of outrage and demonstrate a renewed commitment to keeping our communities safe."

The Colorado shootings came only days after a 19-year-old gunman opened fire at a popular mall in Omaha, Neb., killing eight people and himself.

"The violence ... against young missionaries in Arvada and against worshippers at New Life Church in Colorado Springs would be heart-rending in any season, but it is especially bitter during this time of preparation for Christmas, the birthday of the Prince of Peace," said the Rev. Charles Chaput, Archbishop of Denver in December. "Along with the whole Catholic community in Colorado, I pray that God will heal the suffering inflicted by these terrible events, and sustain the hope and faith of the people at New Life Church, Youth With A Mission and Faith Bible Chapel. For those struggling personally with this sorrow, may God penetrate and redeem even this tragedy with the peace of Christmas and Christ's promise of eternal life."
