Craig had been a respected dentist. Now in a very different type of outfit, wearing handcuffs and shackles, he appeared in court on Thursday where he was formally charged with first-degree murder.

His wife Angela is believed to have been killed by poisoning. Court documents indicate his goal was to kill his spouse so he could be with a woman with which he was having an affair.

KNUS Radio talk show host Steffan Tubbs had been a patient of Craig, "It was stunning... this is a man that I trusted with my personal health, I would have recommended him to anybody."

In court, Craig's attorneys requested a gag order  They complained publicity is endangering the dentist's rights. Court documents show a search on Craig's computer asking "how many grains of arsenic will kill a human?"

There's also an invoice for the purchase of the poison potassium cyanide. 

Earlier this week CBS News Colorado spoke with friends of the Craigs.

Michael Lucero, a neighbor said, "I really felt bad for the family and when I found out what really happened the best I can describe it is like a punch in the gut."

Other court documents revealed a letter from a woman who appears to be a mistress of the dentist.
