When they re-board the doors, they use the Hilti DX 460 MX powder-actuated nail gun that Snoop purchased in the first scene of the season.
Among the people Chris and Snoop murder are Curtis "Lex" Anderson, Little Kevin, Old Face Andre, several New York drug dealers, and a security guard who talked back to Marlo.
The pair were also responsible for intimidating Bodie Broadus into accepting Marlo's drug supply and for recruiting middle schooler Michael Lee into their organization.
In "Final Grades", the last episode of season 4, Snoop alludes to being a lesbian while talking to Bunk during a routine police search.
This occurs when Chris, Snoop, and Michael are about to make a hit on Junebug (a rival drug dealer spreading malicious but trivial words about Marlo's sexuality) and after Omar kills Savino Bratton.
Snoop is murdered by Michael when he rightly suspects that she is about to kill him, due to Marlo's suspicion that he had been talking to the police about the Stanfield organization.
Snoop's name is seen for the first time, very briefly, in a season 3 episode, written on a Post-it Note and being pinned up to the board in the Major Crimes Unit.
