LONDON, Ohio -- The investigation into a missing elderly couple's whereabouts is now focused on their car.

The actual search, however, that was going to take place Saturday at 9 a.m. has been postponed until March 6 at 9 a.m, Fox 28 News reports.

Dick and Gladis Russell's Mercury Grand Marquis is being processed for evidence at the Ohio Bureau of Criminal Identification and Investigation in London, Ohio.

"We'll go over every inch of the vehicle to make sure we don't miss anything," BCI&I Deputy Superintendent of Investigations, Kurt Shearer said.

The vehicle was towed to the central Ohio facility from Princeton, West Virginia, where police found it abandoned in a Walmart parking lot. It was found close to where murder suspect Sam Littleton was captured.

Police believe Littleton murdered 26-year old Tiffany Brown and then stole the couple's car, and drove it to West Virgina. Inside the trunk, and passenger compartment, investigators found blood.

"Our crime scene agents will examine that blood, collect it for DNA analysis, and compare it to
other leads in the investigation," Shearer said.

He added, it could take a few days, or up to a week to process the vehicle.
