MELBOURNE, Fla. -- With thousands of people turning to the Internet to earn some spare cash these days, reports of scams are common, but a group of women said they fell victim to another kind of Internet fraud.

Janet Schulte, of Melbourne, thought she found a good opportunity when a man named Mike answered her Craiglist.org ad offering child care. Mike told Schulte he would pay her $600 a week for her to care for his disabled brother Ryan.

"Supposedly he was in a horrible car accident. From what Mike told me, he had mental impairment, you know, he was pretty badly brain damaged and he had bladder damage," Schulte said.

Schulte said she cared for Ryan for weeks.

"He would basically sit on the couch and watch 'SpongeBob' most of the day, play video games with the kids," Schulte said.

He also requested an occasional diaper change.

"He talked in a whispery baby voice all the time. Always real apologetic," Schulte said.

After two months and little of the promised money, Schulte's husband grew suspicious and decided to follow Ryan. Her husband saw Ryan drive off in a car, apparently cured of his disabilities.

When confronted by Local 6 outside a Melbourne home, Mike denied approaching people through Craigslist about an incontinent brother who needed his diaper changed, but another former caregiver, Danielle Freshour, disagreed.

"I've changed his (Ryan's) diaper many times," Freshour said.

Schulte put a warning on Craigslist.com about the men and learned she was not alone.

"I got an incredible response. Almost immediately five women e-mailed me the same night and two posted other warnings about him," Schulte said.

Schulte filed a police complaint, but police said there was no crime.

"They've got to be able to do something about this guy who is having me change his diapers for kicks, basically," Schulte said. "Since I consented to changing his diapers, there's nothing they could do to prosecute him."

The women still want to warn others to be cautious of anyone offering to pay for "adult child care."

Craigslist.com warns users to meet with other users publicly and always tell a friend or family member about the meeting.

A psychiatrist said some people have a compulsion to be treated like a baby, but if kept private, the behavior isn't harmful.

The disorder is not usually associated with child molesters or sex offenders, but the Brevard Sheriff's Office notified its sex crimes unit of the man's actions anyway.

The man, who has not been identified because he was not charged with a crime, was convicted of felony fraud in 2006 for getting emergency room care under assumed names.
