Relatives of an Indianapolis woman who police said was killed two years ago are offering a $10,000 reward for information leading authorities to whoever killed her, 6News' Ben Morriston reported Tuesday.

The body of Tracy Sissom, 33, was found wrapped in a blanket in a remote area of Brown County in October 2004. Her family had last seen her alive on Sept. 20, 2004.

Police declined to say how Sissom was killed.

Sissom's mother, Becky Sandlin, said Sissom was moving out of an Indianapolis apartment near 30th Street and Post Road on the day she disappeared. Sandlin said she talked to Sissom on the phone that day, and that Sissom was supposed to drive to her parents' house.

"She never came back," Sandlin said Tuesday at a news conference to announce the reward.

State police Sgt. Jeff Deckard said one of Sissom's neighbors had reported seeing a suspicious vehicle.

"A neighbor had seen a dark SUV -- or they thought it was an SUV -- and we've not narrowed it down to a specific SUV or even eliminated a pickup with a camper shell," Deckard said.

Sandlin said she hopes someone will give state police information about the slaying.

"There are people out there that know. They know. Somebody knows. They have to," she said.
