Ex-NFL star Chris Johnson is accused of funding murder-for-hire shootings that left two men dead in 2016 -- this according to explosive court docs obtained by TMZ Sports.
FYI, Johnson has NOT been formally charged with a crime -- and ADAMANTLY DENIES THE ALLEGATIONS -- but officials are clearly laying out their case against the running back ... and it's compelling stuff.
Long story short, officials believe CJ2K rewarded a gang member with cash after the guy allegedly killed two men who were suspected of gunning down Johnson's friend in 2015.
