Park City ? The modest suburban house where Dennis Rader quietly raised his family while terrorizing Wichita as the BTK serial killer sold Monday for $90,000 at auction, far above its assessed value.

The buyers – who declined to identify themselves other than to say that they were real estate investors – told reporters only that they hoped to see all the proceeds go to Rader’s wife, Paula, and the family.

“I am pleased. We are pleased every time we sell a house,” said Lonny McCurdy, owner of McCurdy Auction Service.

The final bid was accepted by the sellers, McCurdy said.

“They said it was satisfactory,” McCurdy said.

Rader pleaded guilty last month to killing 10 people in the Wichita area from 1974 to 1991. He called himself BTK, for “Bind, Torture, Kill,” and sent taunting messages to police about the crimes – the same messages that eventually led to his arrest in February.

The bidding, which started at $40,000, was over in about 15 minutes.

Byron Jones, an Andover resident who offered $60,000 before dropping out of the bidding, said he would have sold the house “inch by inch” on the Internet. Media attention probably doubled the price of the property, he said.

“This guy is famous for what he has done,” Jones said. “I guarantee his house will bring many thousands of dollars – selling it piece by piece.”
