Section 1111.5 Of Chapter 2. The Trial From California Penal Code >> Title 7. >> Part 2. >> Chapter 2.
1111.5
. (a) A jury or judge may not convict a defendant, find a
special circumstance true, or use a fact in aggravation based on the
uncorroborated testimony of an in-custody informant. The testimony of
an in-custody informant shall be corroborated by other evidence that
connects the defendant with the commission of the offense, the
special circumstance, or the evidence offered in aggravation to which
the in-custody informant testifies. Corroboration is not sufficient
if it merely shows the commission of the offense or the special
circumstance or the circumstance in aggravation. Corroboration of an
in-custody informant shall not be provided by the testimony of
another in-custody informant unless the party calling the in-custody
informant as a witness establishes by a preponderance of the evidence
that the in-custody informant has not communicated with another
in-custody informant on the subject of the testimony.
(b) As used in this section, "in-custody informant" means a
person, other than a codefendant, percipient witness, accomplice, or
coconspirator, whose testimony is based on statements allegedly made
by the defendant while both the defendant and the informant were held
within a city or county jail, state penal institution, or
correctional institution. Nothing in this section limits or changes
the requirements for corroboration of accomplice testimony pursuant
to Section 1111.
