The suspect drove more than 320km to carry out the attack.
The attack is being investigated as an act of racially motivated violent extremism.
Of the 13 people shot, Police said 11 were black.
Among those reported killed were a man buying cupcakes for his son's birthday and a woman who had gone shopping after visiting her husband at a nursing home.
