FAYETTEVILLE, N.C. (AP) — A pregnant soldier lay dead in the bathtub. Reportedly scrawled on the motel-room mirror in lipstick was a crosshair design — the same symbol contained in a letter that arrived at the local newspaper four days later.

"The following is to inform that I am responsible for the dead body," the typewritten letter read. "It was a master piece. I confess, that I have killed many times before in several states, but now I will start using my role-model's signature. There will be many more to come."

While police dismiss the notion there's a serial killer on the loose, the letter now appears to be an important piece of evidence in the investigation into the death last month of Army Spc. Megan Touma, a 23-year-old soldier at Fort Bragg.
