You got the details all wrong. The neighbor was John Favara. He was not pulling out of his driveway. He was driving down the street, on his way home from work. Gotti's son, Frank, was riding not a bicycle, but a motorized mini-bike. Favara struck Frank when Frank darted into the street. Favara did not move out almost the day after. The accident took place in the month of March. Favara remained where he lived. But after receiving death threats and all sorts of phone and mail harassment (he even went to the Gotti home to personally apologize, but was beaten by Victoria Gotti with a baseball bat), he put his house up for sale. Only two days before closing on the sale of his house, Favara was kidnapped. Witnesses saw Favara get hit over the head with a 2x4 and dragged into the back of a van. Neither his body, nor body parts were ever found. Gotti and his wife were conveniently out of town, in Florida, during the kidnap.
Thanks for the details! Obviously, I only dimly recalled what I read years ago. BTW, I live in Florida, and a family member who had worked for a connected family told me that the family always went to Florida when they were going to have a case of Italian lightning (insurance fraud arson, for those who don't know) or other inexplicable or inconvenient occurrences.
In any case, it was no laughing matter, and the Mafia were not fun guys - and I have absolutely no idea why the media wants to make them look that way.
