PREREQUISITES: MM #16 (Mr. Phillips), Bail Bond Mission 2, Must be Trevor.
COMPLETION REQS: N/A
After a small amount of time has passed from the last bail bond mission, Maude will shoot you an email about this new mission. Our target this time is a man named Glenn Scoville, a banker and adrenaline junkie.
The last known location photo is actually a picture of the top of Mount Chiliad. Go figure, right? Well, just in case you don't know where that is, it is north of the Alamo Sea (which is north of Trevor's safehouse), and is the highest peak in the game. So head over there and start heading up! Bring along a motorcycle, ATV, or dune buggy to help make your ascent easier.
Once you get to the top enjoy the sights and then check out the south / south-east slope to find the mark. His adrenaline junkie status is confirmed as soon as Trevor announces himself as he jumps off the mountain with his parachute.
Quickly grab a nearby spare parachute (located next to a motorcycle parked nearby) and jump after him! Trevor will equip the parachute automatically but you have to remember to press the action button to open the parachute. Follow Glenn down; he will land somewhere before he hits the water. As soon as you can chase him down and smack him once to get him to surrender.
From there you just need to jack a vehicle and take him back to Maude. More money for you!
