Richie Incognito says he didn't threaten to shoot ANYONE during a heated incident at an Arizona funeral home back in August ... but admits he "lost his cool" after his father's death.
As we previously reported, cops swarmed Messinger Mortuary on August 20 after staffers secretly called 911 and said Incognito had ordered them to "cut his dad's head off for research purposes." They also claim Richie threatened to shoot the funeral director. Police say they found guns in his truck.
Now, Incognito is finally breaking his silence .
