US woman accused of killing husband before writing grief book sees hearing delayed

Kouri Richins, 33, charged in Utah with murder over death of Eric Richins, who prosecutors say was fatally poisoned with fentanyl

A Utah judge on Wednesday postponed a hearing to determine if prosecutors have enough evidence to proceed to trial in the case of a woman charged with fatally poisoning her husband before she published a children's book about coping with grief.

Judge Richard Mrazik delayed the hearing until 18-20 June after prosecutors said they would need three days to present their evidence against Kouri Richins, whose lawyer says she is innocent.
