According to Decider, conspiracy theorists believe Lam had tuberculosis at the time of her death, and that somehow, she was connected to an outbreak of the disease in Los Angeles that same year.

The theory states that Lam was sick, and her odd behavior resulted from new medication used to treat tuberculosis. Variations of it are that Lam may have been the subject of an experimental new tuberculosis drug or a kind of human biological weapon sent to spread the disease in L.A., who was silenced for knowing too much.

Conspiracy theorists rest their idea around the L.A. outbreak and the fact that one of the tests to detect tuberculosis is called the LAM-ELISA test. The lipoarabinomannan enzyme-linked immunosorbent assay helps diagnose cases of tuberculosis meningitis, a form of the disease that primarily affects children, per the National Library of Medicine.

Unfortunately for Reddit, their tuberculosis theory is off base. Lam’s autopsy revealed she did not suffer from tuberculosis, and though she did have traces of medication, these were tied to prescription drugs she took to control her bipolar disorder. The L.A. Coroner’s Office declared her death an accidental drowning.
