KING-TV of Seattle reports police contacted the owner of the seekingarrangement.com website last week asking for information about Julia Biryukova.
Owner Brandon Wade says he gave police login information and account messages.
Wade says the page was created July 25 by someone in Washington state identifying herself as JB. The free profile required no proof of identity. It features nine photos of Biryukova and says she is looking for real man who would pay her $3,000 to $5,000 a month.
Biryukova told police her son, Sky Metalwala, disappeared Nov. 6.
