A man and girlfriend were standing outside their truck when it was hit by George McGee's Tesla in April.
Dillon Angulo, 27, and Naibel Benavides Leon, 22, were standing outside of their truck parked off Card Sound Road when they were hit by a car.
The video from a Monroe County deputy's body worn camera shows rescue efforts to save Angulo, who was lying unconscious with blood around him.
Leon later died in hospital - a tragedy her partner only found out weeks after the crash. He still uses a wheelchair and suffered memory loss.
Monroe County State Attorney hasn't filed any charges against McGee. They have discussed the incident with Florida Highway Patrol (FHP) as they investigate.
'How can somebody be free three months after they've killed somebody and have caused so much pain in other people's lives,' Angulo told NBC 6 on Saturday. 'To me, that's not right.'
Angulo continued that he thought he was going to die at one point and added: 'It has been rough.'
