 Matejka’s  family told the Guardian people have also taken to making memes with his photos and pairing them with crude captions. The shooting survivor was forced to shut down his social media accounts  but his loved ones are still being targeted by those who believe the deadly incident was a hoax.
 Matejka  traveled to the festival from  his  native Canada with girlfriend Amanda Homulos to celebrate  his  30th birthday.
When the gunfire broke out   Matejka  was knocked to the ground after a bullet struck  him  the head. Homulos  who was not injured  was able to make it inside the car of another concertgoer  who drove them to the hospital.
