Accused Golden State Killer Joe DeAngelo was a regular at a strip club where he was known as a cheap creepy old racist, DailyMail.com can reveal.

And the ex-cop suspected of at least 12 murders and 50 rapes got 'sweaty and stuttery' after going on a racist rant when a stripper suggested he needed to take DNA test to prove he was 100 per cent white himself.

'All of a sudden he got stressed out for no real reason,' the dancer, a 21-year-old blonde told DailyMail.com. 'Now I think I know why.'

Father-of-three DeAngelo, 72, drove to the all-nude Gold Club Centerfolds in Rancho Cordova, California, 12 miles from his home in the Sacramento suburb of Citrus Heights, at least once every two weeks. He liked to sit at a table in the middle of the club a few feet from the main stage.

Accused Golden State Killer Joe DeAngelo, 72, was a regular at a strip club by his home, where he was known as a cheap creepy old racist

DeAngelo drove to the all-nude Gold Club Centerfolds (their dancers pictured above) in Rancho Cordova, California, 12 miles from his home in the Sacramento suburb of Citrus Heights, at least once every two weeks

Dancers said that DeAngelo liked to sit at this table in the middle of the club a few feet from the main stage (pictured above)

While at the club (its exterior pictured above) one night, DeAngelo went on a racist rant and called non-white people in the room 'nasty and dirty'

'I've only been working here since January. I work three or four nights a week and I have seen him here at least four times, so, yeah, he's a regular,' the stripper said.

'I never saw him spend a dime, he never asked for lap dances,' the dancer, who asked DailyMail.com not to disclose her stage or real name, said.

She added: 'He sat back from the stage so he wasn't expected to tip the girls as they danced.

'He would just pay his entrance money, come in and stare at the girls. He would be there at about five or six o'clock and maybe stay for a couple of hours.'

The dancer, who wore a pink bikini top and black panties - both of which she discarded when she was called up on stage in the middle of her interview with DailyMail.com - said she immediately recognized DeAngelo when his picture was revealed following last week's arrest.

She said she approached him in the hope of giving him a lap dance and initially thought he was funny and charming.

'He introduced himself to me as Joe and we got talking and he said he had been a cop in Auburn and in the Bay Area,' she recalled.

While DeAngelo had been a police officer in the small town of Auburn, California, in the 1970s, there is no record of him working in the San Francisco area.

Dancers at the Gold Club said that DeAngelo was standoffish to some strippers but funny and charming to others

The strip club has semi-private cubicles where patrons can pay $20 for more private dances

One dancer said that DeAngelo would show up around 5pm or 6pm and stay for a couple of hours and just 'stare at the girls'

Prices at the club vary from day to day and hour to hour, but by arriving before 7pm, DeAngelo could get a seat for a $15 cover charge

'He said he had guns and could protect us,' she said. 'I wasn't really sure what he was talking about. He had that quirky grandfatherly feeling.'

But all of a sudden, he blurted out a shocking statement.

'Out of the blue he suddenly told me his girlfriend had sex with her sister,' the dancer said. 'Then he said: "It's an Indian thing".

'I said: "What do you mean, like Indian from India or Native American?" and he said "Native American:.

'Then he told me how he hated the fact she was Native American and suddenly launched into a really horrible racist rant, pointing to everyone in the club who wasn't white and calling them nasty and dirty.

'I told him he should be careful, perhaps he should take one of those DNA tests you see on TV to see if he's all white - I don't know why I thought of it, I think I'd just seen an advertisement for one of them.

'He got all strange and wiped his hand over his face and said: "They'll never get my DNA". But he said his sister had taken one of those tests. He got all sweaty and stuttery. Now it makes sense.'

Neighbors have described DeAngelo as an angry man liable to go on rants over seemingly unimportant issues.

Dancers said that while DeAngelo was standoffish, he 'behaved' himself while at the strip club and did not touch any of the women. Pictured above, the 72-year-old appears in court after his arrest

The Gold Club dancer said she got the feeling the woman DeAngelo was talking about wasn't a real girlfriend.

'I don't know why, but it seemed he was talking about someone he paid for sex,' she said.

On another occasion, the dancer said she spoke to DeAngelo and he seemed in a bad mood.

'I asked him what was wrong and he told me he had had a fight with his girlfriend,' she recalled. 'He said: "I'm not getting any p***y tonight."'

The dancer said DeAngelo's racist rant really put her off him and after that she tried to avoid him - but that didn't stop him from trying to talk to her.

'But one time I was over by the bar he came over and tried to talk to me,' the dancer said. 'Now, in a funny way, I kind of feel glad I found out he was such a horrible racist. I wouldn't want to think that that nice old man might have killed so many people.'

She said apart from his rants, DeAngelo behaved himself while in the club.

'He wasn't grabby or anything,' the dancer said. 'Some men try to touch all the time. He wasn't like that.'

Joseph James DeAngelo is believed to be responsible for at least 12 murders and more than 50 rapes in California between 1975 and 1986 (victims are seen above)

Another dancer, a heavily tattooed brunette, told DailyMail.com she had seen DeAngelo in the club several times but he had rebuffed her attempts to talk to him.

'He just seemed so grumpy and standoffish,' she said. 'Word gets around in clubs like this about who will spend money and who won't - so I didn't bother trying to talk to him.'

DeAngelo, a father of three grown daughters, is currently in custody in Sacramento and is believed to be the violent murderer known variously as the Golden State Killer, the East Bay Rapist, the Original Night Stalker and the Diamond Knot Killer.

His reign of terror covered a huge swath of California ranging nearly 500 miles from north of Sacramento to Orange County and lasted from 1976 to 1985.

Police now believe he may also be a serial burglar who killed one man in Visalia, California in an earlier crime spree which hadn't previously been linked to the other cases.

In many cases he broke into houses when both husband and wife were at home and tied up the man while he raped the woman.

One man who had gone to a community forum with cops and questioned how anyone could get away with raping a woman when her husband was there, was later a victim, The New York Times reported.

Investigators believe the murderer had been at that meeting, heard the man talk and then decided to target his family.

Police have now finished combing through the beige-colored house, removing boxes of evidence, guns, cars a motorcycle and a boat, among other items. Sheriff deputy Kim Mojica is seen on Thursday carrying boxes of evidence taken from DeAngelo's home in Citrus Heights, California

DeAngelo left law enforcement in 1979 after he was fired for stealing a can of dog repellant and a hammer. He went on to work for nearly three decades in a supermarket chain warehouse before retiring last year.

He was nabbed after police matched DNA from items he discarded with samples found at his many crime scenes.

They used a sample from an Internet genealogy site submitted by a relative to narrow their search to him, according to the Sacramento Bee.

Sacramento County Chief Deputy Attorney Steve Grippi told the paper they compared crime scene DNA to online 'open-source' profiles until they found the relative.

After months of comparisons, cops finally narrowed the DNA down to DeAngelo on April 19 and began watching him. The following day they got a sample from an item he discarded.

They sent the sample to the county crime lab which found 'overwhelming evidence' that after 44 years they had finally got their man.

Still they decided they needed a second match and that was recovered last Monday.

'The second sample was astronomical evidence that it was him,' district attorney Anne Marie Schubert told the paper.
