Branson told deputies he found the grenade three or four years ago while cleaning out a veteran’s home and decided to keep it. He was unsure whether it was active, said Flagler County Sheriff’s Office spokeswoman Melissa Morreale. “He thought it was cool, so he kept it in his toolbox and was driving around with a grenade for quite some time,” Morreale told The Post. Along with the grenade, deputies found the life-size clown mannequin — as well as amounts of cocaine, marijuana and two pipes with suspected drug residue.
