Mobile signal jammer

The cell phone signal jammer is a device Ken Carlton uses to prevent phones kept in his cab from being traced. Its role is practical and specific: it helps conceal the phones taken from his captives, turning the vehicle into a repository that frustrates efforts to locate them.

Installation and Use

After taking Jill Richards’s phone from her handbag, Ken passes it through the partition between the cab’s rear and front compartments and places it with four other phones in the glove box. The jammer is attached to the dashboard, where its indicator light flashes steadily. The narration states that while the phones remain in the cab, they cannot be traced.

Role in Concealment

The device is part of Ken’s handling of captives’ possessions: he removes Jill’s phone from her belongings, adds it to the collection already in the vehicle, and secures the cab before returning to the house. The jammer’s stated effect makes the phones’ presence in the cab harder to turn into a means of locating them. Its importance lies in this function, not in any described technical specifications; the account gives no further details about its operation or range.
