Law enforcement officials continue to analyze forensic results from items that were sent to the state crime lab in the brutal double murder of a rural Sycamore man and his mother.
64-year-old Robert Wilson and his 85-year-old mother Patricia died nine months ago from blunt force trauma after a forced entry into their home.
Officials believe the crime occurred between 7:45 p.m. and midnight Aug. 15; family members were ruled out as suspects.
The Wilsons' stolen Chevy Impala was located near Lincoln Park Zoo in Chicago soon after, but the DeKalb County Sheriff's Office said surveillance video of the vehicle was unable to catch the driver’s face.
Sheriff Roger Scott said the biggest challenge in the investigation is that it took more than 24 hours for the crime to be reported, which he said is less common in an urban community.
“There’s always a lot of people or seems to be people around, or the crime is reported rather quickly," he said, "so we’re kind of at a disadvantage with that time gap."
Scott said there aren't any new leads, but he encourages the public to come forward with information.
“We certainly hope things move in a positive direction," he said. "But it’s one of those crimes that may take a month or years to solve. We’re confident we’ll be cleared at some point in time."
Police are offering a $25,000 reward for information leading to an arrest.
