DENVER, COLORADO (ANS) -- Matthew Murray, the man who police say shot and killed four people at two separate locations in Colorado on Sunday, died from a self-inflicted gunshot wound, the coroner's office said Tuesday.

“The death of Matthew Murray has been ruled a suicide,” CNN reported the El Paso County Coroner's Office said in a statement. “It should be noted that he was struck multiple times by the security officer, which put him down. He then fired a single round killing himself.”

Police Sgt. Skip Arms told The Associated Press that Murray shot himself in the head.

Police say before Murray, 24, went down, he shot and killed sisters Stephanie and Rachael Works, ages 18 and 16, and wounded their father, who was in or near their car in the parking lot of New Life Church in Colorado Springs, Colorado.

Murray also wounded two other people with his assault rifle as he re-entered the church.

One of them, Larry Bourbonnais, said he tried to distract the shooter before security guard Jeanne Assam made her move.

“I'm telling you right now, she's the hero, not me. It was the bravest thing I have ever seen,” CNN reported Bourbonnais said. “She had no cover. He fired -- I heard him fire three. I heard her fire three. And she just began -- she kept yelling 'Surrender!' the whole time. And she just walked forward, like she's walking to her car in the parking lot, firing the whole time.”

Bourbonnais said when he and Assam reached Murray, “He had slumped backwards, slid down on the floor, and expired.”

The assault at New Life Church came about 12 hours after Murray shot and killed two people and wounded two others at the Youth With a Mission center in Arvada, Colorado, 80 miles away, CNN reported police said.

A memorial service was scheduled for Wed. for the two staff members there who were killed, Tiffany Johnson, 26, and Philip Crouse, 24, according to the group's co-founder, Peter Warren.

Brady Boyd, senior pastor of New Life Church, told reporters Tuesday he and his church had already forgiven Murray, even though he is still angry about what happened.

“But being angry and being unforgiving are two different things,” CNN reported Boyd said.

Boyd said his congregation would hold its regular services as scheduled next weekend.

Boyd said members will hold a family meeting Wed. “We will gather to worship, pray, mourn and begin our healing process,” CNN reported a statement said.

“If we could find some motive, some written motive or some recorded motive that he gave, it would be helpful for the healing process, sure, because that is the question: Why? Why, why, why is going to be the number one question that we answer,” CNN reported Boyd said.

CNN said some answers may be found from a warning Murray posted online just 90 minutes before he went to New Life Church.

The message attributed to Matthew Murray -- using the screen name "nghtmrchld26" -- mirrored the wording of a warning posted in 1999 by Eric Harris before he and Dylan Klebold went on a shooting rampage at Columbine High School.

"I'm coming for EVERYONE soon and I WILL be armed to the @.%$ teeth and I WILL shoot to kill," the posting obtained by CNN affiliate KUSA-TV read. This was the same wording used by Harris, with the exception of symbols used to replace an expletive.

Murray, who lived in Englewood, Colorado, just 13 miles from the Columbine campus, titled his entry, “You Christians brought this on yourselves.” It was published on a Web site for people who had left Pentecostal Christianity.

The message, first reported Monday by KUSA-TV, was taken offline by the site's administrator after he talked to the FBI, but has since been put back online.

CNN reported that Joe Istre, president of the Association of Former Pentecostals (AFP), said the posts were restored so people could “try and make sense of all this chaos.”

The posting on the online forum, maintained by the group, indicated it was published at 11:03 a.m. on Sunday -- two hours before the shooting at New Life Church and about 11 hours after the shooting at Youth With A Mission.

In earlier postings, "nghtmrchld26" railed against the Rev. Ted Haggard, founder of New Life Church.

Haggard was fired last year after a former male prostitute alleged he had a three-year cash-for-sex relationship with him. Haggard admitted buying methamphetamine from the man but said he didn't use it.

In a post from March, CNN reported Murray complained that because of his mother's concerns about video games and popular music, "I remember having to listen to everything in secret, at very low volume levels or with headphones, whether it was video games, TV, DVDs, or music/radio."

He also wrote, "My mother would search EVERYWHERE on a regular basis. You'd have thought I was hiding methamphetamines (which her favorite pastor, Ted Haggard was found guilty of) or something serious, but it was all over DVDs, CDs, and video games.”

FBI Received Tip Warning Them about Gunman

KUSA reported the FBI got a tip in between two shootings on church campuses warning them about Murray because of the violent messages he had posted on the AFP Forum.

At least one visitor to the site was alarmed and contacted the FBI promptly, before the second attack, the site's administrator said.

KUSA said the FBI confirmed they got the warning around 10:30 a.m. on Sunday and contacted Arvada Police. According to the FBI, agents were examining Murray's many posts on the Web site when the shootings at New Life took place.

Seven months before the shootings, Marlene Winell, a former psychologist, heard of Murray's on-line postings. KUSA said she posted a message publicly to him writing, “I can see that you are in a great deal of pain and I'd like to invite you to contact me. One of your readers has contacted me to express concern, and I'd like to be helpful if I can. People do care about you and there is hope.”

KUSA said Winell wishes she could have helped Murray.

“This was a person who was definitely in a lot of pain,” Winell told KUSA. “I simply invited him to contact me because I can understand when someone is experiencing these feelings they are very intense feelings.”

Murray responded to Winell's postings saying, “I've already been working with counselors.” He also wrote, “It's so funny how many people want to help you and love you and counsel you... when there is money involved.”

Winell told KUSA that Murray never contacted her directly, even though she left her e-mail address and contact information on the Web site where Murray posted his writings.

Winell told KUSA that despite Murray’s writings, she never thought he would act out violently.

"I am surprised he took it that far," she said. "People have a lot of anger but rarely do people take it that far."

KUSA reported that Murray had been making posts on the anti-Pentecostal Web site for months before the shootings.

One post, called “My YWAM Horror Story,” complained about being removed from the Arvada youth mission program.

"Why was I told that I couldn't be a missionary because I wasn't `social enough'? I was told that I was `an introvert,"' nghtmrchld26 wrote. "Everyone else got to go on their outreaches, except for a few who lied about smoking (cigarettes). The authoritarianism and hypocrisy is outrageous."

KUSA reported that in an Oct. 6 post, nghtmrchld26 wrote about his anger at the church.

"We'll make our own religion and be our own God's (sic) instead (of) listening to some abusive pedophile church like what I was raised in telling us who's `saved' and who's not," the person wrote.

"During this dark period I've realized this is not the way just to be a martyr. I can't walk alone any longer, and I'll fight for the ones who can't fight. If I lose at then (sic) least I tried. If I have to give my life you can have it."
