ROCHESTER, Pa. -- A woman, her common-law husband and her daughter were arrested on charges of prostitution in Beaver County.

Kimberly Delay, 44, of Rochester, and her daughter Britney Day, 21, are accused of operating a prostitution ring over the Internet.

Donald Britton, 40, who is Kimberly Delay's common-law husband, handled the money, police said.

Delay and Britton were arrested and charged with illegal prostitution when police raided their house in the 400 block of Irvin Avenue Thursday afternoon.

“You could go on and send a private message to get the services,” said Cpl. Eric Hermick of Pennsylvania State Police in Beaver. “We did the homework and know this happened through the Internet.”

According to Channel 11's News exchange partners at the Beaver County Times, the mother and daughter used the Craigslist Web site to solicit their clients, or "johns."

Police said the investigation is expanding because the sex appointments were made online and now officials are tracking down the johns, using their Internet Protocol addresses.

Hermick said, “We don’t know where this will lead us, but we are going to follow the evidence.”

Delay told Channel 11 News Thursday evening that she is innocent of all charges.

“No. There’s not a prostitution ring. I’m 44 years old. Who wants a 44-year-old prostitute?” said Delay.

However, police said Britney Delay, who was already in jail on a probation violation for an unrelated charge, admitted to operating the prostitution ring.

Police said they expect to make several more arrests in the case soon.
