Rope (Strongest kind to tie her up."

The court documents say Valle also exchanged online messages with an alleged co-conspirator about planning to abduct and cook Victim 1. In one of the exchanges, according to the court documents, Valle allegedly wrote, "She does look tasty, doesn't she?"

"You do know if we don't waste any of her there is nearly 75 lbs of food there," the other person replied, according to the court documents.

The complaint also says Valle negotiated in February with a different person on a price for Valle to kidnap a different woman, whom the complaint identifies only as Victim 2. Valle wrote of kidnapping the woman for the alleged co-conspirator for $5,000, and resisted the co-conspirator's attempt to lower the price, the complaint says.

"Like I said this is very risky and will ruin my life if I am caught," Valle wrote, according to the complaint. "I really need the money and I can't take under $5,000 for [Victim 2]."

The complaint also accuses Valle of illegally getting information about a third woman, Victim 3, from the National Crime Information Center database. The name of that woman matched a name that investigators found in Valle's alleged files of women on his home computer, the complaint says.

The women in Valle's alleged database live in the United States and overseas, according to a law enforcement source with knowledge of the investigation. At least three of them know Valle, another law enforcement source said. Court documents show one of the alleged targets dined with Valle at a Maryland restaurant.

The 100 women are in the process of being identified, then notified by federal and local authorities.
