Sixers and Nets legend Julius ?Dr. J? Erving has filed a lawsuit against a security guard company and the developer of Alaqua Lakes, the Orlando Sentinel is reporting.  Erving is blaming them for the death of his 19-year-old son, who drove into a retention pond and drowned two years ago.

Cory Erving disappeared May 28, 2000 sparking a major manhunt.  He was found five weeks later a half-mile from his home when the Seminole County Sheriff's Office dragged a small irrigation pond and found his car at the bottom.

Investigators concluded he was doing the same thing he had often done before -- taking a shortcut home on a dirt road used by Alaqua Lakes construction crews. This time, though, investigators theorized, he didn't see the pond, maybe because of debris piled up beside the road, and plunged into the water.
