Hunter Biden's 'crack pipe' crisis in Arizona has been dragged into his paternity case, as he's accused of having a history of using stolen identities to conceal his location, according to legal papers obtained by DailyMail.com.

Private eye Dominic Casey filed a notice of identity theft on Monday morning, as the Orlando, Florida-based investigator seeks to be made a party in Biden's case with his baby mama Lunden Roberts in Independence County, Arkansas.

Casey rehashed the scandal of Biden, 49, leaving his rental car in Prescott, Arizona in October 2016, and calling Hertz to pick it up. Among the items authorities found in the car were a glass pipe, cocaine residue and his deceased brother Beau Biden's Delaware Attorney General badge.

No charges were ever brought against Biden because local prosecutors said there was a lack of evidence that the pipe had been used by him, due to no fingerprints being found.

Casey claims Biden used the fake name of Joseph McGee to call Hertz as well as citing Beau's badge as alleged proof of Biden's 'history' of using fake identities.

But Judge Holly Meyer shot down Casey's attempt to get involved hours later, as well as 'defrauded investor' Joel Caplan, saying neither had any right to intervene and strongly cautioned them not to file any 'frivolous pleadings' in the future or otherwise face 'being held in contempt, punished by fine, incarceration or both.'

Also on Monday, Roberts demanded that Biden show up for a court appearance scheduled for Tuesday, blasting his attempt to skirt traveling to Arkansas, pointing to his alleged $150 million fortune, and accusing him of trying to delay the case.

Meanwhile, Hunter tried again to postpone Tuesday's hearing, claiming he didn't receive 'proper notice' and said he wouldn't be able to make it in time. He requests, if the judges denies his motion, to appear via telephone.

Later on Monday, after a hearing over the phone, Judge Meyer rescheduled the Tuesday in-court hearing for January 29.

Casey filed papers in late December 2019, seeking to become a party in the case. He claims he has obtained Biden's bank account records and handed them over to Roberts' legal team.

Casey has claimed Biden was involved in a 'counterfeiting scheme' in Ukraine that accumulated a $150 million fortune, and his bank records are 'subject of known felonies including fraud and counterfeiting.'

Casey heads up D&A Investigations and he is known for pursuing right-wing conspiracy theories. During the Casey Anthony trial, he claimed a psychic told him where to find Caylee's body.

In court papers filed on Monday, Casey claims a Hertz employee received a call at 10am on October 28, 2016, from a man who called himself Joseph McGee.

The court filing states that 'McGee [stated] his friend was sick, and left the vehicle overnight with the keys in the gas cap area because they did not know what to do.

'A bag containing the suspicious items, a cellar telephone (Apple) belonging to Shauna Stranglr aka Puma St. Angel and a Delaware Attorney General Badge belonging to his deceased brother Joseph R. Beau Biden III were provided to Officer Jeremy Brazell.'

Beau Biden died aged 46 in May 2015 of brain cancer.

The police report notes there was a glass pipe collected from the car. Testing later showed it contained cocaine residue, but there were no fingerprints on it

Biden told the New Yorker that while on his drive from California to Arizona he hadn't slept in days and claims on a bendy mountain road, he thought he saw a large owl fly over his car and appeared to follow him.

A Hertz employee told the New Yorker last June that he found a crack pipe inside the car and there was a line of white powder residue on one of the consoles.

The police report notes a glass pipe was collected from the rental car. Testing later concluded it contained cocaine residue, but there were no fingerprints on it.

No charges were ever brought against Biden because local prosecutors said there was a lack of evidence that the crack pipe had ever been used by him.

After finding evidence of narcotics inside the rental car, an officer attempted to contact Biden using the 'fake name' he gave as Joseph McGee.

Casey's filing states: 'On November 31, 2016, Officer Jeremy Brazell called the Verizon cellar telephone number, a female answered and stated her name was Puma aka Shauna Stranglr and she would have Joseph call him.

'The telephone number belonged to Shauna Stranglr aka Puma. She is the co-founder of Grace Grover Center aka Rejuvenation & Performance Institute in Arizona.'

Biden told the New Yorker that while on his drive from California to Arizona he hadn't slept in days and claimed on a bendy mountain road, he thought he saw a large owl fly over his car and it appeared to follow him.

Unsure whether or not he was hallucinating, Biden claims he dropped off the car and had a van from the rehab facility pick him up.

During Biden's rehab stint, Beau's widow Hallie flew out to visit Hunter and that's when they decided to become a couple, months after becoming extremely close after his brother's death.

'We were sharing a very specific grief,' he told the New Yorker. 'I started to think of Hallie as the only person in my life who understood my loss.'

Roberts filed the suit last May and it was later revealed the two had met while Roberts worked as a stripper in Washington D.C. The 28-year-old (right) wants his financial records to determine how much he should pay in support, as Biden's finances are in the spotlight in connection with Trump's impeachment. On Monday, she blasted his attempts to skirt traveling to Arkansas, citing his alleged $150 million fortune

Biden is being sued by his baby mama Lunden Roberts for child support for their now 17-month-old child.

Roberts filed the suit last May and it was later revealed the two had met while Roberts worked as a stripper in Washington D.C.

Originally, Biden claimed the child, whose gender is being kept secret, was not his but DNA testing proved he is the father.

The 28-year-old wants his financial records to determine how much he should pay in support, as Biden's finances are currently in the spotlight over his former position at the Ukrainian energy company, which has been at the center of Hunter's entanglement in President Trump's impeachment.

On Monday, Roberts blasted Biden's attempts to skirt traveling to Arkansas, citing his alleged $150 million fortune.

She claims he has defied the court's orders to disclose his finances and income.

Biden's team also filed papers on Monday morning, seeking to have 'defrauded investor' Joel Caplan's 'intervener motion' thrown out.

Caplan filed papers in late December seeking to become a party in the case, much like Casey, claiming he wanted Biden's bank records to allegedly prove Hunter received $1.5 billion from Chinese companies that hustled Americans out of their life savings.

Judge Meyer threw out Caplan's motion on Monday morning.
