Ted Bundy admitted to 30 murders and may have killed as many as 100 women

The lawyer who defended serial killer Ted Bundy has spoken out, saying he believes the murderer was 'born evil' and intentionally sought the death penalty.

Attorney John Henry Browne, 71, opened up about his chilling experience with the notorious killer for a new episode of the documentary series 'In Defense Of', set to air on Oxygen on Sunday.

Though Bundy admitted to committing 30 murders across several states in the 1970s, authorities fear he may have had a hand in as many as 100 slayings. Bundy was executed by the state of Florida in 1989 at age 42.

The infamous killer was best known for his ruse of charming young women while pretending to need crutches or a cast, and then killing them at other locations which he'd repeatedly revisit to groom or abuse the bodies in sick postmortem rituals.

Browne first became involved in Bundy's defense when the killer was living in Seattle free on bail, pending his trial in a kidnapping case in Utah.

'Ted knew he was being followed - there was no subtlety to what the task force was doing while he was in Seattle,' Browne recalled in a preview for the new episode.

'Ted actually enjoyed the attention he was getting from the media and police. They were following him everywhere, and that became almost comical, because Ted would make fun of them - he'd make cookies for the cops. He'd knock on their windows, like make coffee and take it to the surveillance vehicles,' said Browne.

'When I first met Ted, my strategy was to minimize the public's belief that he was 'the Ted,'' said Browne.

But over the course of a decade representing Bundy, the defense attorney eventually came to find that he was the worst of the worst.

'Ted was the only person in my 40 years of being a lawyer that I would say that he was absolutely born evil,' Browne told Fox News in a separate interview.

'This is really the only person, after representing thousands of clients in 40 years that I would say that about,' he continued. 'I didn't want to believe people were born evil, but I came to the conclusion that Ted was… He had this energy about him that was clearly deceptive, very sociopathic.'

Bundy was convicted of kidnapping in Utah in 1976, by which time the handsome psychopath had come under suspicion for dozens of murders spanning multiple states.

One year into his sentence in Utah, he was extradited to Colorado to face charges in the murder of 23-year-old nurse Caryn Campbell.

Bundy, acting as his own attorney in the Campbell case, failed in one escape attempt in Aspen, Colorado. Browne believes he had a 'death wish' and wanted to get to a state that had the death penalty.

'He asked me in Colorado where a person would actually go to get the death penalty and I said, immediately, Florida or Texas,' said Browne. 'And then he escapes a second time and goes to Florida.'

Bundy effected a daring, meticulously planned jailbreak on New Year's Eve 1977, taking advantage of the holiday to shimmy through the ceiling to the warden's office, don the warden's street clothes and walk out the front door of the jail.

Just weeks later, Bundy went on a violent sexual rampage though a Florida State University sorority, killing two young women and seriously injuring two others.

Soon after, the sociopath abducted and murdered 12-year-old Kimberly Diane Leach.

On February 8, 1978, just five weeks after his jailbreak in Colorado, Bundy's final murder spree came to an end with his arrest, when he was pulled over in a stolen car.

Reports at the time indicated that Bundy was offered a pre-trial plea bargain, in which he would plea guilty to the murder of Leach and the two sorority sisters, in exchange for 75 years in prison.

'Nobody would ever believe you could get a plea bargain for Ted Bundy, but I did with one other lawyer,' recalls Browne.

'He turns around and says, 'I'm not going to do it.' That's when we told him we weren't going to help him anymore. We felt he had a death wish. So yes, I think it could be reasonably concluded that Ted had a death wish,' the lawyer said.

Browne described Bundy's personality as a series of masks, cunningly designed to charm, manipulate and deceive.

There was just one moment before the trial in Florida, the attorney said, when the masks slipped, and he felt he got a glimpse at another side of Bundy as he sat in his jail cell.

'He said to me, "John, I want to be a good person, but I'm just not," said Browne. 'He actually fell to the floor cell and had tears in his eyes when he said that… It was the first time I ever saw him truly emotional.'

'He was acknowledging that he was basically an evil person who has done awful things and he wished he wasn't that anymore… He snapped out of that after three hours and went back to the facade of Ted.'

Bundy was convicted and sentenced to execution. On death row, he admitted to 30 murders, but said there were others so heinous that he would never confess.

The full episode of 'In Defense Of' airs on Sunday, July 15 at 8pm on Oxygen.
