Lester Crest

Lester scopes the Vangelico jewel store with Michael. The two pose as customers, photograph the security and ventilation, and lay out the smart vs loud heist approach options.
Casing the Jewel Store is a mission in Grand Theft Auto V, given to Michael De Santa by Lester Crest.
Michael meets Lester at his garment factory before the duo drive to the Vangelico Jewelry Store. Once on location, Lester instructs him to walk in and use a pair of camera-glasses to take pictures of the displays, ventilation and alarm system.
Afterwards, the player must drive around the block and go upstairs to the roof via a building in renovation in order to scout for the store's ventilation sources.
Back at the garment factory, Lester sets up a planning board and offers two ways to execute the heist to Michael:
Choosing the Loud approach will unlock the following setup mission: *Carbine Rifles
Choosing the Smart approach will unlock the following setup missions: *Bugstars Equipment *BZ Gas Grenades
