I went back to the office in my house to check e-mail before I went to bed. Lucy rarely called when she could use the computer to tell me how and where she was. My niece was an FBI agent, the technical specialist for their Hostage Rescue Team, or HRT. She could be sent anywhere in the world at a moment’s notice.

Like a fretful mother, I found myself frequently checking for messages from her, dreading the day her pager went off, sending her to Andrews Air Force Base with the boys, to board yet another C-141 cargo plane. Stepping around stacks of journals waiting to be read and thick medical tomes that I recently had bought but had not yet shelved, I sat at my desk. My office was the most lived-in room in my house, and I had designed it with a fireplace and large windows overlooking a rocky bend in the James River.

Logging on to America Online, or AOL, I was greeted by a mechanical male voice announcing that I had mail. I had e-mail about various cases, trials, professional meetings and journal articles, and one message from someone I did not recognize. His user name was deadoc. Immediately, I was uneasy. There was no description of what this person had sent, and when I opened what he had written to me, it simply said, ten.

A graphic file had been attached, and I downloaded and decompressed it. An image began to materialize on my screen, rolling down in color, one band of pixels at a time. I realized I was looking at a photograph of a wall the color of putty, and the edge of a table with some sort of pale blue cover on it that was smeared and pooled with something dark red. Then a ragged, gaping red wound was painted on the screen, followed by flesh tones that became bloody stumps and nipples.

I stared in disbelief as the horror was complete, and I grabbed the phone.

“Marino, I think you’d better get over here,” I said in a scared tone.

“What’s wrong?” he said, alarmed.

“There’s something here you need to see.”

“Are you okay?”

“I don’t know.”

“Sit tight, Doc.” He took charge. “I’m coming.”

I printed the file and saved it on my A drive, fearful it would somehow vanish before my eyes. While I waited for Marino, I dimmed the lights in my office to make details and colors brighter. My mind ran in a terrible loop as I stared at the butchery, the blood forming a vile portrait that for me, ordinarily, wasn’t rare. Other physicians, scientists, lawyers and law enforcement officers frequently sent me photographs like this over the Internet. Routinely, I was asked, via e-mail, to examine crime scenes, organs, wounds, diagrams, even animated reconstructions of cases about to go to court.

This photograph could easily have been one sent by a detective, a colleague. It could have come from a Commonwealth’s Attorney or CASKU. But there was one thing obviously wrong. So far we had no crime scene in this case, only a landfill where the victim had been dumped, and the trash and tattered bag that had been around her. Only the killer or someone else involved in the crime could have sent this file to me.
