Data extracted from Santa Clara Vice Mayor Anthony Becker’s phone and presented in court this week showed the city official deleted Signal — an encrypted messaging app he allegedly used to leak the civil grand jury report — several months after the leak occurred.

Fernando Ramirez Jr., a criminalist with the Santa Clara County Crime Laboratory who performed a forensic analysis of Becker’s phone, appeared as an expert witness at his trial on Tuesday and Wednesday. After reviewing documents showing his work, Ramirez testified in Santa Clara County Superior Court in Morgan Hill that the information “suggests that an uninstall was performed” on Becker’s phone on Dec. 28, 2022 at 9:09 a.m.
