Denied the knowledge provided by physical evidence, a detective walks into the interrogation room without leverage, without any tool to pry truth from suspects or reluctant witnesses. The bastards can lie themselves blind and the detectives, disbelieving and frustrated, can scream at them for lying themselves blind. Without physical evidence, there is only stalemate.
Beyond those who don’t want to talk, the physical evidence keeps honest those who willingly volunteer information. Seeking to cut deals on their own charges, inmates at the city jail routinely claim to have heard fellow prisoners boast about or confess to murders, but detectives seriously pursue only those statements that include details from the crime scene that only a perpetrator could know. Likewise, a confession obtained from a suspect that includes details of the crime known only to the killer is inherently more believable in court. For these reasons, a detective returns from every crime scene with a mental list of essential details that he plans to withhold from newspaper and television reporters who will be calling the homicide office half an hour after the body hits the ground. Typically, a detective will hold back the caliber of the weapon used, or the exact location of the wounds, or the presence of an unusual object at the scene. If the murder occurred inside a house rather than on a street where a crowd can gather, the investigator may try to withhold a description of the clothes worn by the victim or the exact location of the victim’s body in the house. In the Latonya Wallace case, Landsman and Pellegrini were careful not to mention the ligature marks on the victim’s neck or that a cord or rope was used in the strangulation. They also kept the evidence of sexual molestation, or at least they tried to keep it—a week after the murder, a colonel felt the need to reveal the motive for the slaying to concerned parents at a Reservoir Hill community meeting.
From a detective’s point of view, no crime scene is better than a body in a house. Not only does a murder indoors mean that details can be kept from gathering crowds or prying reporters, but the house itself offers immediate questions. Who owns or rents the house? Who’s living there? Who was inside at the time? Why is my victim inside this house? Does he live here? Who brought him here? Who was he visiting? And call for a wagon, because everyone in the place is going downtown.
To murder someone in a house, a killer has first got to gain entry, either at the invitation of the victim or by forcing a door or window. Either way, something is gained by the investigator. The absence of forced entry suggests that the victim and assailant were probably known to each other; forced entry allows for the possibility that the killer has left fingerprints on a windowpane or door frame. Once inside a house, the killer may well touch a variety of utensils and smooth surfaces, leaving more latent prints. If the killer sprays some bullets around, most of the stray shots will appear as holes in the walls, in the ceiling, in the furniture. If the victim struggles and the assailant is injured, blood spatter or pulled hairs will be more easily discovered in the limited confines of a living room. The same thinking applies to loose fibers and other trace evidence. A lab tech can take a vacuum to a three-bedroom house in under an hour, then turn the vacuum bag’s contents over to the whitecoats for sifting in the fifth-floor labs.
But a body in the street offers less. Kill a man while he’s walking to the liquor store and you can rest assured that no civil servant is going to suck the lint from the 2500 block of Division Street. Shoot a man outside and there’s a good chance that most of the projectiles will not be recovered. Kill someone in the street and often the crime scene will provide a detective with little more than some blood spatter and a couple of spent casings. Not only are the opportunities for recovering physical evidence fewer, but the spatial relationship between the killer, the victim and the scene is obscured. With an indoor murder, the killer and victim can both have discernible connections to the location; out in the street, a detective can’t check utility bills or rental agreements to learn the names of people associated with his crime scene. He can’t collect the photographs and loose paper, telephone messages and notes scrawled on pieces of newspaper that would be waiting for him at an indoor murder.
Of course, a detective knows that a street murder carries its own advantages, notably the possibility of witnesses, the second element of the investigative triad. For this reason, one alternative has long held a special place in the catalogue of urban violence, particularly in a rowhouse city such as Baltimore, where every block has a rear promenade. Kill someone in an alley and you minimize the risks of both physical evidence and witnesses. In Baltimore, the report of a body in an alley is bound to bring groans and other guttural noises from the throat of a responding homicide detective.
Only one scenario, in fact, offers less hope than a body in an alley. When a Baltimore homicide detective is called to the woods and brambles along the far western edge of the city, it can only mean that one of the city’s inhabitants has done a very bad thing and done it very, very well. For two generations, Leakin Park has been Baltimore’s favored dumping ground for those who depart this vale by bullet or blade. A sprawling, thickly wooded wilderness surrounding a small stream known as the Gywnns Falls, the park has been the scene of so many unlicensed interments as to warrant consideration as a city cemetery. In New York, they use the Jersey marshes or the city’s rivers; in Miami, the Everglades; in New Orleans, the bayou. In Baltimore, the odd, inconvenient corpse is often planted along the winding shoulders of Franklintown Road. Police department legend includes one story, apocryphal perhaps, in which a class of trainees searching one quadrant of the park for a missing person was reminded by a Southwestern District shift commander, with tongue planted in cheek, that they were looking for one body in particular: “If you go grabbing at every one you find, we’ll be here all day.”
Veteran detectives declare that even the most unremarkable crime scenes offer some information about the crime. After all, even a body in an alley leaves a detective with questions: What was the dead man doing in that alley? Where did he come from? Who was he with? But a dump job, in Leakin Park or in an alley, in a vacant house or a car trunk, offers nothing. It stands mute to the relationship between the killer, the victim and the scene itself. By definition, a dump job strips a murder of any meaningful chronology and—with the exception of whatever items are abandoned with the body—of physical evidence.
Whatever and wherever the scene, its value as the baseline of a murder investigation depends entirely on the detective—his ability to keep out the rabble and maintain the scene itself; his capacity for observation, for contemplating the scene in its totality, in its parts, and from every conceivable angle; his willingness to perform every task that could possibly yield evidence from a particular scene; his common sense in avoiding those procedures that would be meaningless or futile.
The process is subjective. Even the best investigators will admit that no matter how much evidence is pulled from a scene, a detective will invariably return to the homicide office with the discomforting knowledge that something was missed. It is a truth that veterans impress upon new detectives, a truth that emphasizes the elusive quality of the crime scene itself.
Whatever happens before the scene is secured can’t be controlled and in the wake of a shooting or stabbing, no one objects to the behavior of uniformed officers, paramedics or bystanders who alter a scene in an effort to disarm the participants or administer aid to the victim. But apart from such necessary actions, the first uniform at the site of a murder is supposed to preserve the scene from being trampled, not only by the locals, but by his fellow officers as well. For the first officer and those who arrive after him, good police work also means grabbing hold of any potential witnesses who happen to be standing around.
The first officer’s duties end upon the arrival of a downtown detective, who, if he knows his business, will start by slowing everything down to a crawl, making it much more difficult for anyone to express stupidity in any truly meaningful way. The more complex the scene, the slower the process, giving the detective some semblance of control over the uniforms, the civilian witnesses, the bystanders, the crime lab technicians, the ME’s attendants, the secondary detectives, the shift commanders and every other human being in the vicinity. With the exception of the civilians, most of this crowd will know the drill and can be trusted to do their jobs, but as in everything else, assumption is mother and midwife to the most egregious mistakes.
