Edwina nodded. The same question had already occurred to her.
Without being obvious, Edwina studied the young woman. She was small, slight, dark, not really pretty but provocative in an elfin way. She looked Puerto Rican, which she was, and had a pronounced accent. She had said little so far, responding only briefly when spoken to.
It was hard to be sure just what Juanita Nunez's attitude was. It was certainly not co-operative, at least outwardly, Edwina thought, and the girl had volunteered no information other than her original statement. Since they started, the teller's facial expression had seemed either sulky or hostile. Occasionally her attention wandered, as if she were bored and regarded the proceedings as a waste of time. But she was nervous? too, and betrayed it by her clasped hands and continuous turning of a thin gold wedding band.
Edwina D'Orsey knew, because she had glanced at an employment record on her desk, that Juanita Nunez was twenty-five, married but separated, with a three-year-old child. She had worked for First Mercantile American for alm ost two years, all of that time in her present job. What wasn't in the employment record, but Edwina remem bered hearing, was that the Nun ez girl supported her child alone and had been, perhaps still was, in financial difficulties because of debts left by the husband who deserted her.
Despite his doubts that Mrs. Nunez could possibly know how much money was missing, Tottenhoe continued, he had relieved her from duty at the counter, after which she was immediately "locked up with her cash."
Being "locked up" was actually a protection for the employee concerned and was also standard procedure in a problem of this kind. It simply meant that the teller was placed alone in a small, closed office, along with her cash box and a ca lculator, and told to balance all transactions for the day. Tottenhoe waited outside.
Soon afterward she carted the operations officer in. Her cash did not balance, she informed him. It was six thousand dollars short.
Tottenhoe summoned Miles Eastin and together they ran a second check while Juanita Nunez watched. They found her report to be correct. Without doubt there was cash missing; and precisely the amount she had stated all along. It was then that Tottenhoe had telephoned Edwina.
"That brings us back," Ed wina said, "to where we started . Have any fresh ideas occurred to anyone?"
Miles Eastin volunteered, "I'd like to ask Juanita some more questions if she doesn't mind." Edwina nodded.
"Think carefully about this, Juanita," Eastin said. "At any time today did you make a TX with any other teller?"
As a ll of them knew, a TX was a tell er's exchange. A teller on duty would often run short of bills or coins of one denomination and if it happened at a busy time, rather than make a trip to the cash vault, tellers helped each other by "buying" or "selling" cash. A TX form was used to keep a record. But occasionally, through haste or carelessness, mistakes were made, so that at the end of the business day one teller would be short on cash, the other long. It would be hard to believe, though, that such a difference could be as large as six thousand dollars. "No," the teller said. "No exchanges. Not today." Miles Eastin persisted, "Were you aware of anyone els e on the staff, at any time today, being near your cash so they could have taken some?" "No."
"When you first came to me, Juanita," Eastin said, "and told me you thought there was some money gone, how long before that had you known about it?" "A few minutes."
Edwina interjected, "How long was that after your lunch break, Mrs. Nu nez?"
The girl hesitated, seeming less sure of herself. "Maybe twenty minutes."
"Let's talk about before you went to lunch," Edwina said. "Do you think the mon ey was missing then?" Juanita Nunez shook her head negatively. "How can you be sure?" "I know."
The unhelpful, monosyllabic answers were becoming irritating to Edwina. And the sulky hostility which she sensed earlier seemed more pronounced.
Tottenhoe repeated the crucial question. "After lunch, why were you certain not only that money was missing, but exactly how much?" The young woman's small face set defiantly. "I knew" There was a disbelieving silence.
"Do you think that some time during the day you could have paid six thousand dollars out to a customer in error?" "No."
Miles Eastin asked, "When you left your teller's position before you went to lunch, Juanita, you took your cash drawer to the cash vault, dosed the combination lock and left it there. Right?" "Yes." "Are you sure you locked it?" The girl nodded positively. "Was the operations officer's lock closed?" "No, left open."
That, too, was normal . Once the operations officer's combination had been set to "open" each morning, it was usual to leave it that way through the re mainder of the day.
"But when you came back from lunch your cash drawer was still in the vault, still locked?" `'Yes."
"Does anyone else know your combination? Have you ever given it to anyone?" "No."
For a moment the questioning stopped. The others around the desk, Edwina suspected, were reviewing mentally the branch's cash vault procedures.
The cash drawer which Miles Eastin had referred to was actually a portable strongbox on an elevated stand with wheels, light enough to be pushed around easily. Some banks called it a cash truck. Every teller had one assigned and the same cash drawer or truck, conspicuously numbered, was used normally by the same individual. A few spares were available for special use. Miles Eastin had been using one today.
All tellers' cash trucks were checked in and out of the cash vault by a senior vault teller who kept a record of their removal and return. It was impossible to take a cash unit in or out without the vault teller's scrutiny or to remove someone else's, deliberately or in error. During nights-and weekends the massive cash vault was sealed tighter than a Pharaoh's tomb.
Each cash truck had two tamperproof combination locks. One of these was set by the teller personally, the other by the operations officer or assistant. Thus, when a cash unit was opened each morning it was in the presence of two people the te ller and an operations officer.
Tellers were told to memorize their combinations ant not to confide them to anyone else, though a combination could be changed any time a teller wished. The only written record of a teller's combination was in a sealed and double-signed envelope which was kept with others again in double custody in a safe deposit box. The seal on the envelope was only broken in event of a teller's death, illness, or leaving the ba n k's employ.
By all these means, only the active user of any cash drawer knew the combination which would open it and tellers, as well as the bank, were protected against theft.
A further feature of the sophi sticated cash drawer was a built-in alarm system. When rolled into place at any teller's position at a counter, an electrical connection linked each cash unit with an interbank communications network. A warning trigger was hidden within the drawer beneath an innocuous appearing pile of bills, known as "bait money."
Tellers had instructions never to use the bait money for normal transactions, but in event of a holdup to hand over this money first. Simply removing the bills released a silent plunger switch. This, in turn, alerted bank security staff and police, who were usually on the scene in minutes; it also activated hidden cameras overhead. Serial numbers of the bait money were on record for use as evidence later.
