The accused was found guilty by a jury of second degree murder of his six-year-old daughter and attempted murder of his seven-year-old son.
The offences occurred when the accused, motivated by a desire to spite his estranged wife, administered sleep medication to the children in a hotel room.
The court considered the egregious breach of parental trust, the vulnerability of the victims, and the need for denunciation and general deterrence.
The accused was sentenced to life imprisonment with parole eligibility set at 18 years for the murder, and a concurrent 10-year sentence for the attempted murder.
