STUART, Iowa - New developments in the Bill and Kay Wood case have led investigators to closely study the last time the couple was seen alive.
The Woods disappeared on July 30 and were last seen at an antique auction in Stuart, about 30 miles west of Des Moines.
"I think there is a really big chance that something happened in Stuart," said Bill Wood's brother, Henry.
Last week, the Iowa Division of Criminal Investigation revealed Bill Wood was shot to death inside their charred home near Norwalk. Kay Wood still hasn't been found.
The Woods were last seen at the auction and were excited about what was inside. An advertising flyer said the auction had everything from old guns and diamonds, to Indian artifacts and fancy furniture.
"Bill probably has some antiques that are very rare. He liked nice stuff. He probably had expensive stuff. If he found something he wanted, he bought it," said Henry Wood.
The Wood family now worries that love for expensive antiques somehow contributed to his death and her disappearance.
"Just somebody there that may have seen that they bought something expensive or they could've even been talking to somebody and mentioned what they have. It has to be a robbery of some sort," Carolyn Harkin, Bill Wood's sister, said.
The family also revealed that Bill Wood's red pick-up truck that was found in Kansas City actually got to Kansas City before their home near Norwalk burned down.
"Whether they followed him home, we even wonder if they didn't kidnap Kay from the auction and make him come home for something, you know," Wood said.
A travelling auction company out of Texas put on the auction that day. News Channel 8 called them to see if they saw or heard anything involving the Woods that day, but the auction company hadn't returned calls as of Monday night.
"There are just so many questions we have," Harkin said.
Bill and Kay Wood's families have spent the three weeks since their disappearance combing the countryside near Norwalk, and now near Stuart, looking for any sort of clues.
They posted sketches of a man in Stuart City Hall. It's the man police said was seen walking away from the Wood's truck in Kansas City. The Iowa Division of Criminal Investigation said Monday they still don't know who he is.
It has the family begging for answers to questions that keep them up at night.
"What could have happened, where could she have gone? What advantage do they have to take her and kill her and if they did, what did they do with her," Wood asked.
"I can't imagine for Kay's kids if they have to live the rest of their lives and don't ever find her. I just can't imagine how you could even live with that," said Harkin.
