Police would not say what sparked their interest in the elder Welch. It resembles a mug shot taken of Welch a few years later — in — when he was arrested in a burglary case in Montgomery. Neighbors said that they saw police go into his house recently. She said that Richard Welch and his wife are hard-working people who raised their grandchildren. At a news conference Thursday afternoon, Bedford officials also said they will convene a grand jury to further investigate the case, and it will start meeting Friday. The police focus on the elder Welch developed during their recent, renewed investigation in the case. Neither man has been charged in the case. In recent weeks, investigators have focused their attention on land in Bedford County, Va. Back then, he was 18 and, according to police, was known to stay in homeless shelters and hotels. Authorities have declined to comment on what role they think either might have had in the disappearance or detail what evidence they have gathered. But earlier this year, police said they were investigating Lloyd Welch, 57, a former carnival worker who was at the shopping center that day and later assaulted girls in South Carolina and Delaware. They have been digging there and looking for clues in the Taylor Mountain area. She said they are trying to get Welch family members to turn on each other. Police developed a sketch partly based on that description, they said. Officials said the second man, Richard Allen Welch, 69, is the uncle of Lloyd Lee Welch , a convicted sex offender who previously was named a person of interest in the disappearance of Sheila and Katherine Lyon. Old case-file documents show that a young girl who was with the Lyon sisters the afternoon they disappeared had described a man who followed the three of them that day.
