Hawes also detailed the bravery of Naeem Rashid, who was killed at the Al Noor mosque. Prosecutors said that after Tarrant left the Linwood mosque he planned to drive to the town of Ashburton and attack a third mosque. Gamal Fouda, the imam of the Al Noor mosque who survived the shooting, told the court that the gunman's actions were misguided.
