Pac mentioned him but didnt diss him in Against All Odds
Pac and stretch were best friends from 91-95, and from what I've read in interviews Pac and Stretch did hang out after the shooting but at some point things went downhill and they stopped talking
He died November 30, 1995 in a drive-bye shooting in Queens that was never solved (although quite a few suspects have been keyed) Stretch's brother Majesty (the other member of the Live Squad) is still rapping and has been on a shitload of mixtapes (including collabos with Mobb Deep, Big Syke, E Money Bags and some old Stretch tracks) over the past couple of years
ironically, 2pac went to Stretch's funeral, while Biggie was a no-show (along with the Bad Boy camp)
Except for Johnny J, I'd say Stretch was probably the person Pac worked with the most (even more than the Outlawz)
