A jury says Lonnie Franklin Jr. Is the Grim Sleeper Killer.

And today we're breaking down the chilling reality that monsters aren't always lurking in the shadows, but

These are individuals who expertly crafted facades of normalcy.

Beloved family members, respected professionals, active community members.

Only to reveal a terrifying capacity for cold blooded murder.

He didn't say it wasn't me or anything like that?

Dennis Nielsen, the man who once called himself the murderer of the century.

Tonight starts a life sentence for six murders in north London.

He once boasted he could have killed 500 people had he not been stopped.

The judge at the Old Bailey said he should stay in prison for at least 25 years.

Nielsen drifted through London as a solitary ex soldier working at a job center, blending into pub corners and long walks home.

Neighbors remembered a polite man willing to help with errands.

That veneer split open in February 1983 when human remains surfaced in the drains at his Cranly Gardens flat.

Eight or even nine of his victims to this day remain unidentified.

Young men with no names, no known addresses.

Others were described as vagrants, hippies and skinheads.

Young men, often unhoused or lonely, brought home for company, who never left alive.

Nielsen killed at least a dozen victims over roughly four years, lived beside their bodies for days or weeks, and

later burned or flushed remains in an attempt to dispose of them.

The quiet life only made the reality more disturbing.

At the time of his arrest, Dennis Nielsen hadn't seen his mother for 10 years.

How do you think Dennis was able to become involved in this kind of problem and then be able to live from day to day?

I just don't understand how this could go on and nobody knowing anything.

The prosecution's now hoping the BTK killer will receive a jail sentence of 175 years.

The former scout leader's good fortune that Kansas did not introduce the death penalty till after his killing spree was over.

The BTK murders terrified Wichita, Kansas for decades while its culprit lived under the veil of absolute normalcy.

Dennis Rader was a married father, a scout leader, a church council president and a code compliance officer.

The last person anyone suspected of violence.

Beginning with the Otero family murders in 1974, Rader killed 10 people while taunting police and media through Letters that described his buying torture kill method.

With us right now is chief of police Richard Lamunion.

How can you be sure that the BTK letter is authentic?

Ron, after reviewing the contents of the letters, Absolutely no question that the only person who would have the type of information that was included in the letter would have to be the killer himself.

He paused for long stretches, then re emerged as if nothing had changed.

When he resumed communication in the 2000s, one message on a floppy disk gave investigators the break they needed.

In 2005, Rader was arrested and the facade finally collapsed.

It had been the most ordinary man in town.

I never met him personally, but there were small townspeople talk, mixed opinions, of course.

He was known to be a very active person in one of the churches up there.

But there were a lot of people that said that he was the type of person that.

One phrase that we've heard frequently creep you out.

FBI profiler Mary Ellen o' toole is using a carefully devised psychological strategy in her interrogation of the Green river killer, Gary Ridgeway.

Her goal is to get him to confess to 44 unsolved homicides where no physical evidence exists that could link him to the crimes.

The serial murder is often imagined as frantic or chaotic.

Gary Ridgway proved it could be systematic.

He put in long hours painting trucks at Kenworth, attended church, married, and made himself forgettable.

Beginning in 1982, Ridgway targeted vulnerable women and killed them with chilling regularity.

Bodies appeared along the green river and in wooded pockets of King county.

Ridgway later admitted he revisited some dump sites long after death had been dealt with.

Started at an early age, but sex and hurting the woman.

And he loved being able to talk, finally, after all these years.

And in doing so, he kind of walked us down the path of all of his murders.

At one point, Gary referred to himself as something like the lean, mean killing machine.

And he was very efficient, like a machine.

By the time he was arrested in 2001, he had confessed to killing dozens of women, eventually pleading guilty to 48 murders, a number investigators believe understates the true toll.

He killed the women he believed no one would miss, and he would drive up to them, and

sometimes he'd even have his son's toys in the front seat.

And that would be a very effective ruse to convince these women that, hey, I can't be that serial killer.

I've got my little boy's Toys in the car.

He was a very normal kind of vanilla type looking person and there was nothing that stood out about him.

Harold Shipman to Harold Shipman appeared here today charged with murder, forgery and attempted deception.

The case against him stems from the death of one of his patients.

Trust is supposed to be the cornerstone of medicine, and Harold Shipman twisted it into a cover story.

In Hyde, Greater Manchester, he built the reputation of a reassuring family doctor, the kind who knew patients by name and stayed with families through births, illnesses and loss.

Andrew Watson, a fingerprint expert, said he'd found the doctor's print in a corner of the will.

He didn't identify any prints belonging to 81 year old Mrs. Grundy.

From the mid-1970s onward, Shipman quietly injected patients, mostly elderly women, with fatal doses of diamorphine, falsifying medical records to conceal the spike in deaths.

When suspicions finally surfaced in 1998, the scale shattered belief.

Official inquiries concluded he likely killed more than 200 patients, making him Britain's most most prolific serial murderer.

In the wake of the Harold Shipman case, Alan Milvern is expected to try and close the loophole which prevents the GMC from temporarily suspending doctors suspected of criminal or incompetent behavior while investigations are carried out.

The GMC insisted tonight that they support the need to change Jeffrey Dahmer.

Milwaukee police found body parts in a North side apartment.

And now they wonder if they've uncovered some kind of dead death factory.

Police hired a private contractor to haul a refrigerator and a tank of acid out of the apartment.

In the 900 block of North 25th street, apartment buildings are full of loners trying not to be noticed, and

Jeffrey Dahmer leaned into that invisibility.

Neighbors complained about foul odors and strange noises, but

most chalked it up to spoiled food or bad wiring.
