NEW CONCORDIA — Investigators examining technology inside the Wren Correctional Research Annex have found enough experimental hardware to make an ordinary unethical laboratory look responsible.

Among the devices recovered were electronically controlled prisoner collars, extensive surveillance systems, reinforced automated stairwells, a vehicle-sized elevator, electrified security batons and equipment connected to experimental biological modification.

The collars appear particularly troubling.

According to records recovered at the annex, one group of executed prisoners could be placed into a catatonic state before being remotely activated and directed toward anyone who was not wearing a collar.

In another section, investigators found evidence of an injectable enhancement compound designed to increase strength, healing and endurance through accelerated tissue growth.

“Anyone calling this a wellness program needs to be arrested twice,” said a city employee briefed on the equipment.

Officials are tracing suppliers and purchase orders for the annex’s systems.

The city now needs to determine whether these technologies were prototypes confined to one building or products somebody intended to manufacture.
