room. There they will be told that it is hospital policy to accept only those patients who are at least clinging to life. The flustered paramedics will mull this over and then decide to take the body back to the street. Upon their return to the death scene, this plan will be given tentative approval by the uniforms, who assume that the ambulance crew must know its business. No doubt the officers would then have done their best to place the cadaver in its original position had not the detective arrived to say thank you, but no thank you. Let’s just say the hell with it and take the poor guy down to the autopsy room.

      Likewise, Robert McAllister, a seasoned detective and a veteran of several hundred crime scenes, will soon find himself standing in a Pimlico kitchen above the blood-soaked body of an eighty-one-year-old man, stabbed forty or fifty times in a brutal housebreaking. On a dresser in a back bedroom is the bent-blade murder weapon, caked with dried blood. So preposterous is it that anyone would disturb such a glaring evidentiary item that McAllister will think it unnecessary to warn against doing so. This crime of omission ensures that a young officer, fresh to the street, will wander into the bedroom, pick up the knife by its hilt and carry it into the kitchen.

      “I found this in the bedroom,” she will say. “Is it important?”

      Assuming that such calamities are avoided and the scene preserved, what remains for the detective is to find and extract the available evidence. This is not done by vacuuming every room, fingerprinting every flat surface, and taking every beer can, ashtray, shred of paper and photo album down to evidence control. Discretion and common sense are valued as much as diligence, and a detective unable to discern the differences among probabilities, possibilities and the weakest kind of long shots soon finds that he risks overloading the evidence recovery process.

      Remember, for instance, that the overworked examiners in the ballistics lab are weeks behind on projectile comparisons. Do you want them to compare your .32 slug with other .32-caliber shootings this year, or should they go back another year? Likewise for the fingerprint examiners, who in addition to the open murders are handling latents from burglaries, robberies and half a dozen other types of crime. Do you tell the lab techs to dust surfaces in rooms that seem to be undisturbed and apart from the scene, or do you have them concentrate on objects that appear to be moved and that are close to the death scene? When an elderly woman is strangled in bed, do you vacuum every room in the house, knowing how long it will take the trace lab to go through one room’s worth of dirt and lint, hair and fiber? Or, knowing that there wasn’t any far-flung, room-by-room struggle, do you instead have the ME’s people carefully wrap the body in the sheets, preserving any hairs or fibers that came loose during the action near the bed?

      With only a few available on each shift to process evidence, the lab techs themselves are a limited resource. The tech working your scene may have been pulled off a commercial robbery to work this homicide or may be needed a half hour later to work another shooting on the opposite side of town. And your own time is equally precious. On a jumping midnight shift, the hours you could spend at one scene might be divided between two homicides and a police shooting. And even with a single murder, hours spent at a scene have to be measured against time that could be spent interviewing witnesses who are waiting downtown.

      Every scene is different, and the same detective who requires twenty minutes at a street shooting may spend twelve hours to process a double stabbing inside a two-story rowhouse. A sense of balance is required at both scenes, an understanding of what has to be done and what can reasonably be done to produce evidence. Also required is the persistence to oversee the essentials, to make sure that what’s being done is done correctly. On every shift, there are those lab techs who arrive at complex crime scenes and provoke sighs of relief from detectives, just as there are others who can’t lift a usable print if a suspect’s hand is attached to it. And if you want the photos to show the location of critical pieces of evidence, you better say as much, or the five-by-eight glossies will come back with every angle but the one you need.

      These are the basic requirements. But there is something else about crime scenes, an intangible on the continuum between honed experience and pure instinct. An ordinary person, even an observant person, looks at a scene, takes in many of the details and manages a general assessment. A good detective looks at the same scene and comprehends the pieces as part of a greater whole. He somehow manages to isolate the important details, to see those items that conform to the scene, those that conflict, and those that are inexplicably absent. He who speaks of Zen and the Art of Death Investigation to a Baltimore homicide detective is handed a Miller Lite and told to stop talking communist hippie bullshit. But some of what happens at a crime scene, if not exactly antirational, is decidedly intuitive.

      There is little else to explain Terry McLarney staring at the seminude body of an elderly woman, rigored in her bed with no apparent trauma, and deciding correctly—on the basis of an open window and a single stray pubic hair on the sheet—that he is working a rape-murder.

      Or Donald Worden, walking down an empty East Baltimore street minutes after a fatal shooting, putting his hand on the hood of one parked car out of twenty and feeling the heat of an engine—a sure sign that the car was recently occupied by persons who fled rather than be identified as witnesses. “There was some condensation on the back window,” he says later, shrugging. “And it was a little ways from the curb, like the driver parked it in a hurry.”

      Or Donald Steinhice, a veteran from Stanton’s shift, who is entirely convinced that the woman hanging from the ceiling of her bedroom has taken her own life, but somehow can’t leave the room until one last detail is settled in his mind. He sits there in the shadow of the dead woman for half an hour, staring at a pair of bedroom slippers on the floor below the body. The left slipper is below the right foot, the right below the left. Was she wearing the slippers on the wrong feet? Or did someone else, someone who staged the scene, place the slippers there?

      “It was the only thing about that scene that really bothered me, and it bothered me for a good long while,” he later recalls, “until I thought about how a person takes off their bedroom slippers.”

      Steinhice finally imagines the woman crossing her legs so as to wrap the toe of one slipper around the heel of the other, prying the slipper off from the back—a common maneuver that would leave the slippers on opposite sides.

      “After that,” he says, “I could leave.”

      FRIDAY, FEBRUARY 5

      In the clear sunlight of a winter morning, the academy trainees feel no sense of foreboding in the alley behind the rowhouses on Newington Avenue. As they crawl through its recesses and kick through its clutter, they find it to be an alley like any other.

      Dressed in the khaki uniforms of the Education and Training Division, the class of thirty-two trainees begins the second day of the Latonya Wallace investigation by moving slowly through the alley and the back yards of every house in the block bounded by Newington and Whitelock, Park and Callow. They search inches at a time, stepping only where they have already searched, picking up each piece of trash with great care, then setting it down with the same deliberation.

      “Go slowly. Check every inch of your yard,” Dave Brown tells the class. “If you find something—anything—don’t move it. Just go and grab a detective.”

      “And don’t be afraid to ask questions,” adds Rich Garvey. “There’s no such thing as a stupid question. Or at least for right now, we’re going to pretend that there isn’t.”

      Earlier, watching the trainees bound off a police department bus and count off for their instructor, Garvey expressed misgivings. Allowing a herd of new recruits to graze through a crime scene had all the makings of what detectives and military men like to call a clusterfuck. Visions of self-satisfied cadets trampling over blood trails and kicking tiny bits of evidence into sewer drains danced in Garvey’s head. On the other hand, he reasoned, a lot of ground can be covered with thirty-two interested persons, and at this point, the Latonya Wallace probe needs all the help it can get.

      Once loosed upon the alley, the trainees are, to no one’s surprise, genuinely interested. Most of them attack the chore with zeal, picking through piles of garbage and dead leaves with all the fervor and devotion of the newly converted. It’s quite a
