WOULD AN ABDUCTED YOUNG MOTHER BE ALIVE TODAY IF NOT FOR AN ERROR AT THE 911 SWITCHBOARD?, ON "PRIMETIME: CRIME," WEDNESDAY, JULY 23 ON ABC

Would Denise Lee, a devoted young mother and wife, be alive today if not for human error at the 911 switchboard after she was abducted by a stranger? And why did a man fail to act when the alleged kidnapper showed up at his house asking for a gas can and a shovel, with the victim still alive, tied up, in his car? Denise even called 911 herself from her alleged abductor's cell phone, but police were unable to locate her. Jim Avila reports on an unthinkable crime and the mistakes made that may have cost a woman her life. "Primetime: Crime," which investigates crime by going deep inside real cases, uncovering new evidence and getting exclusive witnesses interviews, airs WEDNESDAY, JULY 23 (10:00-11:00 p.m., ET) on ABC.

Twenty-one year old Denise Lee was living her life's dream in the gulf coast of Florida. She had two beautiful sons and was happily married to her husband, Nathan, the man she met as a teenager. But in January 2008, that dream quickly turned into a nightmare when the young mother and daughter of a sheriff's deputy vanished in broad daylight -- kidnapped from her home. Her husband arrived home that fateful day to find his two small children alone and his wife gone. He immediately made the first of what would be several 911 calls that put the local law enforcement and the entire community on high alert. A desperate search to find the kidnapped mother began and even Denise herself was able to get hold of her alleged abductor's phone to call 911, but police were unable to track her location. The hour follows a series of events and calls for help to 911 that occurred to try and save Denise. One woman encountered the alleged kidnapper on the road with Denise tied up in the back of his car. She immediately called 911 and even stayed on the phone to follow him but, because of human error, her call was never passed on to the local police. The "Primetime" report includes witnesses who have never spoken before publicly, video never seen and 911 tapes never heard that take viewers through what happened and what went so wrong.
