I stood my [XXX] nephew up in the front passengers side floorboard of the 2012 hyundia voloster manual transmission with push start . I stepped out of the car on the passage side of the car the car was parked in first gear no one was on the driver's side . I bent over to get my shoes on and baby reached over and pushed the start button on the car the car should not have started since the clutch was not pressed in but unfortunately the car started and lunged forward being on a incline it was as if someone smashed on the gas pedal I ran with the car as far as I could but it was going so fast I could not get into the car to stop it I was drug trying to stop the car the car flew thru a fence , into the woods, down a steep hill then crossed a one lane road traveled up a hill thru another patch of woods before going up hill and hitting a tree all the while our nephew was not in a car seat the car was bouncing side to side when it went off road to cross a creek so I know the baby was thrown around in the car he had to of been that car was going so fast I was screaming in fear that he would not be alive when I made it to the car now the key was in my purse located in the passenger side floorboard where I stood the baby up at so when I reached the car the doors had automatically locked the car was still running and the baby was screaming I could not leave the baby to go get help so I tried to tell him to open the door but like I said he is [XXX] old he didn't know what I was tellin
