Denise Lee, the young mother of two little boys, was seen screaming for help - tied up in the back of a Camaro - by not one but two witnesses. They (and Denise herself) called 911 four times. One witness even told a 911 operator what road the vehicle was driving on.
What happened to Denise? Investigators found her body two days later, naked and tossed into a shallow grave. She had been raped and killed, all because 911 dispatchers never bothered to forward the information to the police.
