Man offering additional $100,000 reward for information in Nancy Guthrie case

(CNN) - A Milwaukee attorney is putting up his own money for information on Nancy Guthrie’s kidnappers.

Michael Hupy, an attorney and president of Milwaukee Crime Stoppers, is offering an additional $100,000 reward in the case.

More than 18,000 tips have been called in to the FBI during the Nancy Guthrie investigation.

The $100,000 reward is being offered for information that leads to the arrest of whoever kidnapped her.

That is in addition to an FBI reward of $100,000.

The reward, which allows people to remain anonymous, is being offered personally by Hupy, who said he already sent the money to Pima County Crime Stoppers.

“I was just kind of appalled that they never enlisted Crime Stoppers help at the beginning or much sooner, and I finally decided if no one else is going to do it, I better do it,” Hupy said.

Hupy said a valid tipster would be able to receive the reward anonymously.

“They’re sent to a location where they’re paid and no one ever knows their name, and if somebody has a phony tip, they’re not going to get a reward in advance because there has to be an arrest,” Hupy added.
