The man who admits killing three people at a Planned Parenthood clinic in Colorado Springs said he dreamt he would be met in heaven by aborted fetuses thanking him for saving unborn babies, court documents show.

Robert Dear, 57, also told police he attacked the clinic on November 27 last year because he was upset about the 'the selling of baby parts'.

During an interview in which he repeatedly recited Bible passages, Dear told police he dreamt he would be 'met by all the aborted fetuses at the gates of heaven and they would thank him for what he did because his actions saved lives of other unborn fetuses'.

It was also revealed he asked several people for directions to the Planned Parenthood address before finally getting the location by calling the clinic.

He wore a homemade ballistic vest made from silver coins and duct tape when he barged into the clinic with four Soviet-style semi-automatic rifles.

He told police he had other weapons including two handguns and a shotgun in his truck.

After killing his first victims, surveillance footage shows him shooing out the window of an employee entrance, going back and forth between the clinic and his truck, and setting up propane tanks in the parking lot that he told police he hoped would explode if he shot them.

'I'm for a speedy trial, this will help the victims' families,' Dear told KKTV in March.

He added: 'Everybody deserves to have information about what's going on and what caused this tragedy events of everything, but they don't want that to come out because it might embarrass the feds and Obama.'

Dear is charged with 179 counts, including murder, attempted murder and assault.

If found competent and convicted, Dear could face the death penalty.

He held police at bay for more than five hours at the clinic, injuring nine others and forcing the evacuation of hundreds of people from surrounding businesses.

The dead included a police officer from the University of Colorado, officer Garrett Swasey, Army veteran Ke'Arre Stewart and mother-of-two Jennifer Markovsky.

None of the three worked for Planned Parenthood.

In courtroom outbursts, Dear declared himself a 'warrior for the babies' and said he was guilty.

The documents show Dear had been nursing a grudge against abortion providers for years.

He told police he admired Paul Hill, a former minister who was executed in 2003 for the 1994 shootings of abortion provider Dr John Bayard Britton and his bodyguard, a retired US Air Force officer named James Herman Barrett, outside the Ladies Center in Pensacola, Florida.

At the time of Hill's execution, some urged that he be spared for fear the extreme wing of the anti-abortion movement would turn him into a martyr.

Dear often talked about Hill, including once when he drove past a North Carolina abortion clinic and again when he learned that Colorado Springs had a clinic, his girlfriend told police.

Dear's comments after the gunbattle even seemed to echo Hill, who spoke of being rewarded in heaven for his actions.

'He was happy with what he had done because his actions ... ensured that no more abortions would be conducted at the Planned Parenthood facility in Colorado Springs,' which has since reopened.

Before the shooting, Dear frequently posted messages online about his anti-abortion views, he told police.

In 2009, he emailed his son a link to a website that has the stated purpose of 'honoring heroes who stood up for the unborn,' with links to information about Hill and others who had targeted abortion clinics.

He also told investigators he put glue in the locks of an abortion clinic when he lived in South Carolina, a common protest technique among activists trying to shut down such facilities.
