Investigators say a Colorado dentist accused of killing his wife researched how to poison her and get away with it while having an affair, searching online for answers to questions like 香蕉视频直播淚s arsenic detectable in autopsy?香蕉视频直播�

On Wednesday, prosecutors are set to present their evidence against James Craig to a judge to show that he should stand trial for first-degree murder in the death of Angela Craig in March.

Police believe James Craig, 45, laced her pre-workout protein shakes with arsenic and cyanide, so he could pursue a relationship with another woman, according to court documents. He has yet to be asked to enter a plea to the charge.

James Craig香蕉视频直播檚 lawyer, David M. Beller, declined to comment on the allegations against his client.

Angela Craig died after being taken off life support during her third trip to the hospital in March. She was married to her husband for 23 years and was the mother of six children, according to her obituary.

As she languished in the hospital, with doctors unable to figure out what was wrong, police in the Denver suburb of Aurora alleged her husband was meeting another woman, fellow dentist Karin Cain, who flew from Texas to visit him. Police began investigating James Craig after his dental practice partner and friend, Ryan Redfearn, told a nurse that Craig had ordered potassium cyanide even though they did not need it for their work, according to an arrest warrant laying out evidence gathered by investigators.

Cain, an orthodontist, told ABC香蕉视频直播檚 香蕉视频直播淕ood Morning America香蕉视频直播� that she has been in the process of a divorcing her husband of almost 30 years when she met James Craig at a dental conference in February. She said they were together for three weeks. Cain said she didn香蕉视频直播檛 willingly have a relationship with someone who was married and she doesn香蕉视频直播檛 like being called Craig香蕉视频直播檚 香蕉视频直播渕istress.香蕉视频直播�

Asked whether she thought Craig killed his wife to be with her, Cain said they hadn香蕉视频直播檛 been planning a future together.

Investigators believe James Craig put arsenic in one of the protein shakes he routinely made for his wife for their workouts on March 6 and then, after she survived, he ordered a rush shipment of potassium cyanide that he told the supplier was needed for a surgery. James Craig had asked an office manager not to open that package but another employee did, leading to its discovery and eventual disclosure to authorities, the document says.

The delivery of a third substance he is accused of ordering, Oleandrin, was intercepted by authorities after they began investigating him, the document says. Oleandrin is a poisonous substance found in the leaves of the oleander plant.

James Craig told Redfearn that he ordered the potassium cyanide for his wife and told a social worker that she had been suicidal and depressed since he asked for a divorce in December, although neither of their children said anything about suicide attempts, according to the arrest affidavit.

Redfearn also told investigators that James Craig was on the verge of bankruptcy and had been having problems in his marriage, according to the document. Angela Craig香蕉视频直播檚 sister, Toni Kofoed, told police that James Craig had drugged his wife about five years ago with an unknown drug because he said he planned to kill himself and did not want her to be able to save him.

Kofoed believes that incident is what James Craig referenced in a series of texts between Angela and James Craig about her symptoms after she first fell ill on March 6. According to the arrest affidavit, James Craig wrote: 香蕉视频直播淕iven our history I know that must be triggering. Just for the record, I didn香蕉视频直播檛 drug you. I am super worried though.香蕉视频直播�
