The estranged siblings of a man who owns a quarantined farm in Carroll County have filed a complaint alleging that the farm, where pigs recently vanished, belongs to them.

“The concerns of my clients are that their mother apparently signed deeds at a time when she was ill, and our contention is that [farm owner Carroll Schisler Sr. persuaded her],” said Charles Fisher Jr., the attorney representing sister Iris Wix and brothers Ralph, Donald and Fred Schisler.
