Dave Malucci's locker name tag appears on the wall along with other past characters and a few key crew members. However, in his last appearance, Never Say Never (2001), Dr. Malucci is clearly seen removing his name plaque from his locker door and putting it into a box with the rest of his belongings before leaving the hospital.
After Abby puts the name tags on the wall, when the shot pulls back hers is more crooked than when she initially put it on.
