Conversely, if she had been a willing participant in the robbery scheme, it seemed likely to the investigators that her death would have come after the robbery had been successfully accomplished.

It seemed like a solid theory to me as Lawton Cross had recounted it during my first visit to his home. It was probably the way I would have gone if I had been allowed to stay on the case. But ultimately the theory didn’t pay off. Cross told me that he and his partner had worked a full field investigation on Benton but never came across the one clue that opened up the case. They spent five solid months on her. They traced her movements, personal habits and daily-life routines. They studied her credit-card, banking and telephone data. They interviewed and re-interviewed all family members and known friends and associates. They spent eight days in Columbus alone. Dorsey went to Phoenix to chase down a single hundred-dollar bill. They spent so much time at Eidolon Productions that for one month they were given their own office at Archway Pictures in which to conduct interviews.

And they got nothing.

As is often the case with a homicide, they amassed a wealth of knowledge about the victim but not the key piece of information that led to the identity of her killer. They ended up knowing who she had slept with in college but not where she had spent the last evening of her life. They knew her last meal had been Mexican—the corn tortillas and beans were still in her digestive tract—but not which one of the city’s thousands of such establishments had served her.

And after six months on the case they found absolutely no link between Angella Benton and the robbery, aside from the surface connection of her job as a production assistant for the company that was making the film in which the cash was to play a starring role.

Six months in and they were at a dead end. What they did have in the way of evidence were the forty-six slugs and shell casings collected after the shoot-out, the blood collected from the getaway van and the semen collected from the murder scene. It was all good evidence to have; ballistics and DNA could tie a suspect to a crime with zero doubt—unless your lawyer was Johnnie Cochran. But it was the kind of evidence that was icing on a cake; the kind that links a suspect and weapon already identified and usually in custody. It didn’t do much as far as getting you that suspect. After half a year on it they had the icing but no cake to put it on.

When they reached this dead end it was time to evaluate the case at the six-month mark. This is the point where hard choices are made. The probability of clearing the case is weighed against the need for the pair of investigators to work other cases and help shoulder the caseload of the division. Their supervisor took the case off full-time status and Dorsey and Cross went back into rotation at RHD. They were free to work the Benton case as often and as much as possible, but they also drew new investigations. As could be expected, the Benton case suffered for it. Cross had readily admitted this to me. He said it became a part-time investigation, with Dorsey doing most of the follow-up while Cross concentrated on the new cases they were assigned.
