  In this work we apply the de Broglie-Bohm interpretation of quantum mechanics
to the quantized spherically symmetric black-hole coupled to a massless scalar
field. The wave-functional used was first obtained by Tomimatsu using the
standard ADM quantization and a gauge that places the observer close to the
black-hole horizon. Using the causal interpretation, we compute quantum
trajectories determined by the initial conditions. We show that the quantum
trajectories for the black-hole mass can either increase or decrease with time.
The quantum trajectories that show increasing mass represent the usual
black-hole behavior of continuous energy absorption. The mass-decreasing
quantum trajectories are a purely quantum mechanical phenomena. They can be
physically interpreted as describing a black-hole that evaporates.
