AURORA, Colo. -- Denver activist Alvertis Simmons is no longer working with the family of an Aurora girl reported missing last month.

Simmons was interviewed by Peter Boyles of KHOW Radio Wednesday.

Simmons said the falling out started with a false report that Aarone Thompson had been found. Simmons said that when he told Aarone's father, Aaron, the father's immediate reaction was to pause, lower his head and ask "Where?"

"I'm a father -- I have three girls -- and if one of them was missing and somebody told me they had found her, the first question wouldn't be 'Where?' It would be, 'Is she all right? Is she OK? Is she alive? What's going on?' And then I would ask 'Where,'" Simmons told the Rocky Mountain News after the radio interview.

On the radio program, Simmons related that when he told Thompson of an e-mail that claimed the missing girl had been found, Thompson "kept his head down for 30 seconds, then he brought his head up and asked me 'Where?' and then there was just a look on his face ... he kept shaking his head as if they (police) had caught up to him."

Simmons said he told Thompson that the e-mail said the girl was found in the back yard of the family's home. "There is no way they could have found her in the back yard," he quoted Thompson as saying in response.

Family spokesman Sam Riddle said that Simmons is "reaching a little bit." He called the false e-mail report "a cruel hoax."

Simmons is expected to meet with Aurora detectives Thursday to discuss the case.
