Brandon Sheets is marking his late father's birthday just weeks after his tragic passing. As you know, Storage Wars star Darrell Sheets tragically died last month at age 67. On Instagram Wednesday, marking what would've been his 68th birthday, his son shared a heartfelt video. In the video, he shared some touching moments of Darrell and their family, while he wrote in the caption: "Happy Birthday @darrellgambler thank you for raising me to be the man I am today. . .wish that I could spend just one more day with you." Aww... So sad.
