Shortly before 8 p.m., police received a call from the Axiom La Jolla apartments located on Mahaila Avenue near Regents Road. Visitors told police they came to visit a friend and when they let themselves in the apartment, they read a note on a bedroom door warning them to stay away due to poisonous gas.
No gas or other chemicals were detected. Police said a woman's body was found in the apartment.
An investigation is underway.
