NORMAN, Okla. - The search for clues continues into a suspicious death in Norman.
Nearly one year ago, a Norman mother was found dead inside her home.
To this day, the death remains unsolved.
The family is now offering a $2,000 reward for information that helps solve the case.
The victim's mother says it's been unbelievably hard not knowing who's to blame for the death.
"My heart is broke, my life is at a standstill until I get some kind of answer," said Roberta Sherlock.
Sherlock's 27-year-old daughter, Owachige Osceola, was found dead inside her home last September.
Most of the family lives in Florida, but Osceola lived in Norman so she could share custody of her 4-year-old daughter.
For nearly one year, the circumstances of the Oseola's death has remained a mystery.
"We're struggling with it and trying to deal with why," said Sherlock.
"Just like the family needs closure, we need to close this case," said Norman police Captain Tom Easley.
Norman police wouldn't say how the victim died inside the home.
The case has not been ruled a homicide, but police say it is very suspicious.
"We have investigated this and put a lot of effort into it, but there are still a lot of unanswered questions," said Easley.
So far, no one has ever been arrested for the death but the Oseola's mother hopes someone comes forward with information that explains what happened and why.
"This is my daughter that has been taken away from me," said Sherlock. "I can't sit still and let someone walk away with what they did to my daughter."
Anyone with information on the case is asked to contact Norman police.
Again, there is a reward being offered by the victim's family.
