COEUR d'ALENE - Deputies are investigating an alleged attempt to extort money for the return of an iPhone that was stolen from a Silverwood bathroom last month.

According to a Kootenai County Sheriff's report filed on Monday, the victim, Caroline Clark of Naches, Wash., was visiting Coeur d'Alene on July 25 and took her child to Silverwood.

Clark told police that she left her phone on the sink counter in a family bathroom near the gate of the park while tending to her daughter.

Clark forgot the phone when she left the bathroom. When she returned for it, the phone was gone. Clark told police that she saw one young woman enter the bathroom but Silverwood security officials were able to contact that woman and determined that she did not have the phone.

Two days later, Clark said a young woman contacted her husband's phone from a cellphone with a blocked number. The caller was a young woman, who wanted money to return the phone.

Clark told police that she offered the woman $100 in cash to return the phone because it had several pictures of her children on it.

The caller said that would not be enough money and demanded $700 to return the phone. The caller allegedly told Clark that she needed that much to purchase a new phone for herself.

Clark and her husband finally agreed to paying her $120 in cash and offered to write her a check for the balance.

The caller did not want to give her name, so the Clarks agreed to leave the name line blank,

They arranged a transfer location for the caller to return the phone to Clark without having to meet them personally. The Clarks went to Starbucks on Prairie Avenue and explained to the manager how they wanted to leave an envelope with money in it for him to give to the caller, but only if the caller left the phone.

After leaving Starbucks for a few minutes they returned and the caller had picked up the money and returned the phone.

But the Clarks had not signed the check and the caller texted them when she discovered that. The Clarks offered to meet with her to sign the check, but never heard from her again.

Clark had placed a stop payment on the check, but it was too late, according to the police report.

The caller had put her name on the check, wrote in $1,000 and signed Clark's husband's name to the check.

While police had attempted to contact the caller on the phone she used to text the Clarks, the caller didn't return the detective's message as of Monday.

However, detectives were able to get her name, phone number and bank account information.

"Due to (the caller) informing Clark she would not get her phone back with the irreplaceable photographs unless she paid $700 instead of the offered $100," the detective wrote, "I believe it falls under the extortion code making it a grand theft."

The case is still under investigation.
