Putting a car in park while moving at higher speeds?

So my sister has very little experience driving a car. When I say that, I mean it. She CAN'T DRIVE lol. She has epilepsy, and let me just say this. According to the DMV in the state of FL, if you have epilepsy you can obtain a license as long as you have gone 2 years seizure free. Which she has and is on meds for it. But that's not the problem here. She just really doesn't know how to drive a car. She is 19 and got her license a couple months ago. Anyways, she claims that yesterday she was going 50-60mph and she tried to stop but she couldn't. So she said that she threw the car in park at 50-60mph to stop the car because apparently she had no brakes. She has done that once before but at a much lower speed (2mph) pulling up to where she works. She wasn't fully stopped so she put it in park and it felt like we just rearended someone and the transmission fell out. So how could she have done that going 50-60mph? Is she lying? Am I missing something here? My dad checked the car and he said that the brakes are working just fine, the back ones sound a bit funny but they work and he put brake fluid in it a couple weeks ago and there's no break fluid leak. So how would it be possible that there are suddenly brakes like the brake fairy came along? I feel that if she did do that, the car would have been totaled. The car is a 2001 Ford Escape. I'm 17 btw and I'm supposed to be getting this car ti get me to work after she buys her own (this week) lol.

Fortunately she did not do any damage. The car makes a lot of noise doing that but it will not go in to park at that speed. The shift lever my go to park but the transmission will not, by design.

I have to say I felt like crying when I read she put it in park at 60 mph

Dad gum brake fairy rearing it's ugly head.
