VANCOUVER — A jury has heard that a B.C. couple accused of plotting to bomb the provincial legislature expected their homemade bombs to kill mostly government workers and first responders.

John Nuttall and Amanda Korody are on trial for their alleged plot to plant pressure-cooker bombs on the legislature lawn on Canada Day.

The jury listened to audio recordings of the couple outlining their plan to have the bombs explode mid-morning, well before the first Canada Day activities and hours before the main holiday events.

Nuttall is heard saying that it’s likely the first bomb will kill mostly government workers preparing for the festivities, and the second bomb should be delayed by 15 minutes so first responders would be hit.

A passerby tells Nuttall, Korody and an undercover officer that the “kids’ zone” opens at noon, and Nuttall is adamant the bombs be set earlier enough that children won’t be killed.

Nuttall and Korody have both pleaded not guilty to four terrorism-related charges.
