Colorado dentist accused of poisoning wife to death

(CNN) — A Colorado dentist is facing first degree murder charges after being accused of killing his wife.

45-year-old James Craig’s wife was recently taken off life support.
Investigators believe Craig poisoned his wife with arsenic and cyanide in her pre-workout powder.

Authorities also discovered searches on Google by Craig asking questions such as “is arsenic detectable in autopsy?” Craig is scheduled for trial on Thursday.
