A father accused in his son's death testified Monday that the sick boy's condition worsened after he had appeared to be doing better, but not to the point where his parents were worried.

A medical examiner who did the autopsy on a 19-month-old toddler whose parents are on trial in his death clashed with the boy's father in court Monday.

Despite applications from Lethbridge parents David and Collet Stephan to have certain statements withheld from evidence presented during a retrial for their son's death, statements made when their son was admitted to hospital will be heard by the court.
