A model is proposed to describe a transition from a charged black hole ofmass $M$ and charge $Q$ to one of mass $\bar{M}$ and charge $\bar{Q}$. Thebasic equations are derived from the non-vacuum Einstein field equationssourced by the Coulomb field and by a null scalar field with a nonvanishingtrace anomaly. It is shown that the nonvanishing trace of the energy-momentumtensor prevents the formation of a naked singularity.Comment: 16 pages Late
