FANNIN COUNTY, TEXAS - Karen Weehunt wants answers after she learned that her mother, stepfather and sister are missing.
Her brother, 52-year-old Thomas Taunton, is behind bars as the lead suspect, in what has become a homicide investigation.
"I need to talk to my brother, there's nothing in him that would account for anything like that he doesn't get angry he doesn't have a explosive temper," said Weehunt.
The Fannin County Sheriff says 73-year-old Harold Harpst, his wife 79-year-old Sue Harpst and daughter 48-year-old Regina Taunton were last seen on Sunday.
After combing through their home deputies found overwhelming evidence that led to Taunton's arrest.
"Thomas Taunton was arrested on a Fannin County warrant for capital murder at approximately 3:00PM January 19, 2012 at an automobile repair shop in Louisiana when he had vehicle trouble," said Sheriff Donnie Foster.
That's where investigators searched Taunton's vehicle and trailer.
They won't go into detail about the evidence found inside, but they did say there weren't any human remains.
"At this time the family members are still missing," said Foster, "investigators are still looking for the Harpst vehicle which is still missing."
Sheriff's deputies will spend the weekend searching for the bodies and the van of Harold Harpst, who is a double amputee.
"This vehicle is a silver 2007 Dodge Caravan," said Foster. "The vehicle is a silver 2007 Dodge Caravan with Texas handicap license plate 8CPYH."
Meanwhile, the family's daughter and grandaughter are holding out hope, while trying to make sense of it all.
"You have three people that are obviously where they're not supposed to be and I hope there's an answer somewhere," said Weehunt.
