He will tell you the next location you both need to go to. Drive to the location he asks you to. When you reach the location, you will come across a drug deal that you, Vernon, and the rest of the allies will interrupt.
Take cover behind the trash can at the very left side and take out all the dealers. Do not use any explosives as you might destroy the van with the meth equipment that you need to steal.
After eliminating all the dealers, get into the van and drive it to the drop-off point. Before you can get the blip for the destination, you need to escape the Lost MC gang members.
Keep driving until they stop chasing you. The best way to lose them is to drive as far away from the location as possible. They will eventually leave you alone.
Note that if you get a wanted level, you can easily lose the cops by calling Lester in this mission.
After escaping the bikers, you will get the blip for the drop-off point. Deliver the van to the drop-off point to complete this mission.
Investigation 2 — The Ballas
In the second investigation mission, you need to confront the Ballas suspected of stealing Dr. Dre's music. Once again, stock up on armor and snacks. You're going to need a lot of them.
Make your way to the stated location and you will meet up with Vernon. Enter the Cavalcade and go to the location (Davis) Vernon directs you to.
When you reach the location, you will walk into a gang fight between the Ballas and the Families.
Eliminate all the Ballas in the area and defend the Families. Take cover behind the car or by one of the houses. The Ballas will be on the left side of the conflict.
Once you've defeated the Ballas, you will get a new objective of following Vernon. Follow Vernon to the garage across the street.
Enter the garage and you will find Vernon holding Ballas' P at gunpoint.
After interrogating P, exit the garage and leave the area to complete this mission.
The Final Mission — The South Central Leak
In the final mission, you will need to recover the copy of Dr. Dre's stolen music from the Vagos. Once again, stock up on ammo and armor.
First, drive to Davis Mega Mall to meet up with Vernon and P. When you meet with them, they will be in their own vehicles.
Drive in convoy behind their vehicle and follow them to the Rancho Projects.
Once you reach the destination, you will get a cutscene showing all the Vagos enjoying the leaked Dr. Dre's music out in the open.
After the cutscene ends, you will immediately get put into a gunfight with the Vagos. Get behind the car to get some cover, eliminate the Vagos gang members and advance forward to the next car.
Keep moving forward while carefully eliminating the Vagos.
When you take out the last Vagos member, one of the gang members will come out of the house and drive away in the yellow lowrider, the ride playing Dr. Dre's music.
Get into any one of the vehicles and chase the Vagos member. Eliminate him and steal the vehicle from him.
Once you have the vehicle, deliver it to the agency to complete the mission.
With all three leaks recovered, it's time for the Studio Time mission.
