GTA V: Random Event: Buy Gone Bad

Was it really worth $25,000?

As Franklin, you come across several wounded and dead bodies in the area. One of the guys next to the car with the horn tells you they took the money over the side. Go down the hill and there is another injured guy saying don't take the case. If you do, you immediately get $25,000 and everyone around you croaks.

After about 30 seconds of driving away, two trucks start shooting at you telling you to give them back the case. Not sure how to do it so I just shot them all and kept my winnings. 

GTA V: Hitchhiker: Accident Driver

She wants to leave the scene of the accident pretty quickly.

Driving past Braddock Pass near Mount Gordo as Trevor, you come across an accident. One guy is dead, the girls is badly bleeding but doesn't want you to take her to the hospital. Instead she knows someone in Shady Sands that can help patch her up.

Can you take her to Altruist? No. She is too injured.

Take her to her requested destination quickly and she can be a driver on any of your heists in the future. If you are too slow, she will die in the car.
