Several witnesses had seen Berkley take drugs, or had seen him under the influence of drugs. Berkley was known to use marijuana and cocaine.

An FBI agent testified about numerous letters Berkley sent to one of his girlfriends from jail, while awaiting trial for Martinez?s murder, in which made repeated professions of his love for the young woman but also included negative, crude, and threatening references toward his own mother.
