GTA V: Bounty Hunter: Glenn Scoville

Glenn is a thrill seeker at the top of the mountain. Be prepared to jump.

The third bounty for Trevor is a banker named Glen Scoville. As soon as you find him at the top of Mount Chillad (the one with the cable car) he will jump off. Grab the parachute next to where he jumped and follow him down. You might have to shoot him once before he will accept capture.
