WHEATON, Md. (WUSA9) -- On Monday morning, officials held a news conference on the 1975 disappearance on the Lyon sisters in Bedford County, Va. They are urging anyone with information to share it with police as the FBI's evidence recovery team conducts a two-day search on Taylor's Mountain.
Twelve and 10-year-old sisters Sheila and Katherine Lyon were last seen at the Wheaton Plaza mall in 1975. In the last year, investigators have been focusing on a piece of land in Bedford County. It is owned by one of the two people of interest in the abduction of the sisters.
"This case will be resolved. Our mission focus is to bring these children home, if at all possible," said the Bedford County Commonwealth's Attorney Randy Kratz, who spoke at the news conference.
The commonwealth's attorney made a plea for more information from anyone who believes they may know something that could help with the investigation to come forward to not only help police but help the sisters' parents.
Montgomery County police say that they have worked with other law enforcement agencies and that they have come a long way, but that they will not stop until the people responsible for the girls' disappearance are brought to justice.
They are also warning people who may be withholding information to release that information to police.
Bedford County Commonwealth's Attorney Randy Krantz cautioned that the willful obstruction of the investigation is "morally wrong." He also stated that human information is "key to this case."
Police aren't ruling out the possibility that more physical evidence, including the girls' remains, could be found in Bedford County and that individuals could be charged in relation to the case. When asked if law enforcement officials expected to find human remains on a mountain in Bedford County, Sheriff Mike Brown replied, "We would hope to. I can't say that we would expect to."
A tip led investigators to Taylor's Mountain. Now, a forensic anthropologist from Radford University is helping investigators with the search. Sheriff Brown says the search is expected to last two days.
Officials say that the Lyon family has been updated on progress throughout the investigation.
