Jeremy Freeman Crocker, 62, was last seen in Los Angeles on December 9, 1996. He left home about 1:00 p.m., took public transportation to the Los Angeles Central Library and spent time researching the July TWA Flight 800 crash. Crocker held degrees in mechanical engineering and medical science and had been publicly vocal about his belief that a missile caused the disaster; he spoke about his theories on a radio talk show five days before he vanished.

On the day he disappeared Crocker may have been carrying up to $200 in cash. Mail postmarked the day after his disappearance was received from him, but he was never seen again. His family says it was highly uncharacteristic for him to vanish without notice. Some have suggested he might be in a medical or care facility, but no evidence has confirmed that and there have been no significant leads.

If anyone saw Jeremy Crocker around downtown Los Angeles in December 1996 or has information about his whereabouts, please share what is known.
