The 25-year-old was found stabbed to death in the head, neck and chest in her home as her 2-year-old son sat in his high chair nearby.

Columbus police said they found no signs of forced entry. They said Eugene Wilson, her fiance, found her and called 911 just after 9 p.m. Wilson told the dispatcher that he came home and found their back door open and Jackson dead on a couch.

Police used dogs to track someone who headed away from the north side of the building, but they eventually lost the trail. Investigators took into evidence a discarded rubber glove found on a nearby street, the Columbus Dispatch reported.

While Tuesday marked the four-year anniversary of the brutal homicide of Alicia Jackson, the lead investigator assigned to her case said authorities are still no closer to apprehending her killer.

Steve Eppert, a cold case detective in Columbus, Ohio, said DNA evidence collected from Jackson's Columbus apartment is still awaiting testing at an Ohio crime lab. But the detective said he believes chances are slim the tests will produce the proof necessary to charge the person responsible for killing Jackson.
