Chilling new evidence reveals how Colorado dentist James Craig 'tried to cover up murder after poisoning wife to death'

Officials have found new evidence that shows how accused Colorado dentist James Craig allegedly tried to cover up the murder of his wife. 

Craig, 46, was charged with first-degree murder after being accused of poisoning his wife, Angela, with potassium cyanide, while conducting an affair with an orthodontist in Texas. 

Apart from this, he was also charged with felony count of solicitation to commit tampering with physical evidence after it was revealed that Craig tried to persuade one of his daughters to dispose of key evidence in the case against him. 

Now, Craig is being accused of trying to convince a fellow jail inmate to plant suicide letters in his residence. 

On April 10, the 18th Judicial District Attorney's Office filed a motion to add another 'tampering with physical evidence' count to the accused's charge sheet.

Aurora Police Detective Bobbi Olson, the lead detective on the case, said that she spoke with an inmate who was imprisoned in a cell near Craig. 

She told the judge and court that Craig reportedly told the inmate about his charges  and asked them to place letters in his garage and truck at his home.

Olson testified that the letters were allegedly written from inside the prison and meant to appear as his deceased wife had written them.

According to the detective, the letters were meant to show that Angela was not happy with her life, felt suicidal and was aware about her husband's affair. 

She testified that the entire point of those letters being written and spread across the house was so that law enforcement or defense attorneys could find them letters.

After being arrested a few days after Angela's death, the accused pleaded not guilty to first-degree murder and tampering with physical evidence in October 2023

But on April 10, the 18th Judicial District Attorney's Office filed a motion to add another 'tampering with physical evidence' count to the accused's charge sheet

Olson also told the court that the accused murderer had offered the inmate free dental work or money in exchange for scattering the letters across his house. 

However, the inmate did not take up the offer and instead contacted the authorities. 

But defense attorney Andrew Ho fired back and said that pointed out that the inmate only contacted authorities after Craig's initial preliminary hearing brought in media attention. 

However, the judge ruled the prosecution established probable cause and met their burden of proof. 

Last month, Mark Pray, 55, Angela's brother spoke exclusively to DailyMail.com and said he wanted to thank the Aurora detectives and the DA's office for their 'unwavering dedication for seeking justice' for his 'beloved sister's senseless murder.'

In the days following her death a deeply disturbing picture emerged of the life lived by the devoted wife of 23 years and mother who committed herself to her marriage despite doubts and despite her husband's numerous infidelities, self-confessed porn addiction and a worrisome gambling habit that ran alongside him, 'running his company into the ground'

'The heinous actions of her killer have left a void in the lives of her children, our family, her countless friends, and the world, depriving us of Angie's love and light,' he said.

According to Pray, 'This cowardly act, driven by self-absorption, is a stark reminder of the depths of human depravity.

'The recent revelation of evidence tampering serves as damning proof not only of his guilt in orchestrating Angie's torment and demise but also of his utter disregard for the well-being of those around him, including his own children.'

Pray continued, 'He manipulates and exploits anyone and anything to evade accountability for his monstrous deeds. However, his reckoning is inevitable. Whether in this life or the next, justice will prevail, and he will face the consequences of his actions.'

According to police records, Angela started feeling unwell after drinking a shake that her husband made for her on March 6, 2023. 

Over the next 10 days, she visited hospital three times complaining of nausea and dizziness, but doctors couldn't determine what was causing her illness. 

On March 15, her brother took her to the hospital again. She had a seizure soon afterwards, lost brain function and died.  

After being arrested a few days after Angela's death, the accused pleaded not guilty to first-degree murder and tampering with physical evidence in October 2023. 

It was Pray who accompanied his sister to hospital on the morning of March 15, concerned by the severe headaches and dizziness she was experiencing.

Within two hours of her admission to University Hospital that day she suffered a devastating seizure and began a rapid decline for which medical staff could find no cause.

Ultimately, with Angela on life-support, intubated and in the Intensive Care Unit medics told the family to prepare for the worst.

Angela Craig was taken to the hospital on March 15. She died on March 19, after four days on life support 

She was pronounced brain dead three days later, on March 18, 2023. She was 43 years old.

In the days following her death a deeply disturbing picture emerged of the life lived by the devoted wife of 23 years and mother who committed herself to her marriage despite doubts and despite her husband's numerous infidelities, self-confessed porn addiction and a worrisome gambling habit that ran alongside him, 'running his company into the ground.'

DailyMail.com exclusively revealed that Craig's latest mistress was orthodontist Karin Cain, 50, from Marble Falls, Texas. She flew to be by his side as his wife lay dying in hospital but has since claimed she knew nothing of Craig's supposed plan to start a new life with her.

Meanwhile the 52-page probable cause document filed in Arapahoe District Court detailed the allegedly calculated and 'heinous' plot that saw Craig allegedly research and purchase poisons online then deliver then to his unsuspecting wife through potassium cyanide laced protein shakes.

While Angela deteriorated in the hospital, Craig flew his mistress from Texas, rushing from his wife's hospital bedside to her while telling Angela how much he 'wished he could stay longer.'

It is a reality that shocked all those who thought they knew Craig and who had bought in to the carefully curated image of a picture-perfect family that he presented.

Living in an upscale development with parks, a nature reserve and playgrounds, the Craigs were a family who seemed to have it all.

But the probable cause affidavit claims that, behind closed doors, Craig drugged Angela five or six years ago, in an incident he attempted to explain away by claiming he intended to commit suicide and didn't want her to stop him.

Meanwhile, his wife was struggling to stay in a marriage riven by his repeated affairs, dire financial problems, and addictions.

Chelsea Norton, 35, who worked for Craig at his Summberbrook Dental Practice, where Angela also worked, told DailyMail.com, 'We're all just in shock. He was a very good guy, like the least likely person for any of this.

'They were the nicest, sweetest family, with such cute kids. I've looked back on my memories to see if there's anything I missed that hinted at anything [that would explain this] at all. But there's nothing.

'He would give motivational speeches and do food for the staff some afternoons.'

Craig had arsenic delivered to the family's home in Aurora, Colorado, days before he allegedly poisoned her  

Yet according to the charging documents, it was in this office – in a darkened exam room – that Craig allegedly researched and purchased poison online. And it was to this address that he had a package containing potassium cyanide delivered March 13.

An earlier delivery of arsenic was found to have been made to his home on March 4.

The later delivery raised concerns when a staff member who had not got the message to not open what Craig described as a 'personal package,' opened it and could think of no medical reason for the purchase.

She Googled the chemical, labeled a biohazard, and realized how closely the symptoms of cyanide poisoning mirrored those being suffered by Angela.

It was Craig's business partner who reported the concerns to a nurse at University Hospital. The nurse in turn informed law enforcement setting in motion the investigation that led to Craig's arrest and charging.

His next trial date is set for June.
