Sixteen-year-old Jennifer was supposed to be baby-sitting her siblings in their home in Brockton, Massachusetts on November 14, 1989, but she decided to go out with friends.
She initially took her younger brother with her, but between 9:30 and 9:45 p.m., she returned to her home to get a sweater and asked her cousin to take care for the children while she went to a party on Emerson Avenue.
Jennifer's cousin came over at 10:00 p.m., and Jennifer then left her home where she was in good spirits at the time and she never returned home.
Jennifer initially went to a female friend's house near her own home, but her friend wasn't home and the girl's mother refused to let her inside. The mother says Jennifer smelled of liquor and appeared to be slightly drunk.
Jennifer left the residence accompanied by an older teenage male friend. They went to a local convenience store at the end of Jennifer's street, less than a minute's walk from her house. Jennifer went inside the store, but her friend didn't feel well and went home while she was inside. That was the last time anyone ever saw or heard from her.
Jennifer was reported missing the next morning when she had not returned home from the party. The friend who last saw her is not considered a suspect in her disappearance.
Authorities originally thought Jennifer had run away from home because she had run away before, but she had never been gone very long and had always stayed in touch with her parents.
Jennifer is described as a very social person who was reportedly happy with her life in 1989. Some of her friends were apparently involved with drugs and possibly other illegal activities, and many of them were not cooperative with police during the initial investigation.
Investigators now believe that Jennifer was abducted shortly after her disappearance, probably by someone she knew and trusted.
In 2003, there was a tip that Jennifer was murdered and her body placed in the trunk of a car and dumped in a pond just outside of Brockton, located minutes from her home. Authorities searched the pond, but they found no evidence.
As of 2018, Jennifer's case remains unsolved and foul play is suspected.
Jennifer is described as a Caucasian female with blonde hair, blue eyes, is 5'4 and weighs between 90 and 100 pounds. She has a scar above her left eyebrow and her teeth are crowded in the front of her mouth.
She was last seen wearing a purple blouse, a black silk jacket with an Iron Maiden patch, dungarees and white sneakers.
