Colorado dentist accused of poisoning wife searched "how to make murder look like a heart attack" online before her death, officer testifies

A Colorado dentist accused of killing his wife searched online for answers to questions such as "is arsenic detectable in an autopsy?" and "how to make murder look like a heart attack" a few weeks before she died, a police detective testified Wednesday.

James Craig conducted the searches on a computer in an exam room at his dental practice in late February in the Denver suburb of Aurora, Detective Bobbi Olson said. The searches came just before his wife, Angela Craig, made repeated trips to hospitals in March complaining of symptoms including dizziness, vomiting and confusion that puzzled doctors, Arapahoe County coroner Kelly Lear said during a hearing to determine if Craig will stand trial for first-degree murder.

Police believe Craig, 45, laced his wife's pre-workout protein shakes with poison 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.
