Federal prosecutors say the man who stalked ESPN reporter Erin Andrews and shot nude videos of her through a hotel room peephole videotaped 16 other women and ran background checks on 30 others, including female sports reporters and TV personalities.

According to a sentencing memo filed Monday in U.S. District Court in Los Angeles, the Internet background checks that Michael Barrett conducted can produce birthdays and home addresses, but it's unclear what information he obtained and how he may have used it.

Barrett has pleaded guilty to interstate stalking and agreed to a 27-month prison sentence. A judge is scheduled to sentence him March 8.

The filing notes that Andrews wants the 48-year-old insurance executive to pay her more than $300,000 in restitution.
