During a press conference Tuesday afternoon about a fatal officer-involved shooting in early May, Pasadena Police Chief John Perez announced that the entire police command staff and Interim Pasadena Fire Chief Bryan Frieders are self-isolating after a member of Perez’s staff exhibited signs of a fever.

“Yesterday there was a group, including myself, that was involved in media interviews,” said Pasadena spokeswoman Lisa Derderian, who is also self-isolating. “One of them this morning woke up with a temperature. As a result, out of an abundance of caution we are isolating at home until the [test] results come back. Based on advice from our health officer, we’ll determine the next course of action if necessary.”

All told, nine city officials — seven from the police command staff, Frieders and Derderian — were asked to self-isolate as they await the results of the COVID-19 test.

In a related matter, Pasadena Public Health Director Dr. Ying-Ying Goh has joined the list of Southern California public health officials receiving death threats. In the past three weeks, officials from LA County and Orange County announced that they too have received death threats after enacting public health orders, with Orange County Public Health Officer Dr. Nichole Quick resigning amid death threats.

Derderian said that Goh understands that this is “misdirected anger” and that she has full support from the community and city management staff.

“She has a large number of supporters throughout the city external and internal,” said Derderian. “Her job is to protect the public and it is based on science and data. It is never acceptable to take out those aggressions on the public health officer or the staff.”

Regarding the shooting, during the press conference police offered video evidence in connection with the May 8 death of Lloyd Nelson Jr. on Corson Streeet near Allen Avenue. Nelson opened fire on an officer following a chase and was killed in the exchange. Perez said the officer had no choice.
