On January 15, 1984, Bruce Bennett lost the battle with a killer who pummeled and sexually assaulted his 26-year-old wife, Debra, and 7-year-old daughter, Melissa. The attack also shattered the face of their 3-year-old daughter, Vanessa.
The 3 year old Vanessa was the only one to survive; though her jaw was crushed, sending jagged bones into her windpipe, she was found when her grandmother, Constance Bennett, checked on the family later that morning when they didn't show up to work at their furniture store.An investigation in which more than 500 people were questioned did not uncover any leads to solve the case.
