January 5, 1987, is the date Dietrich claims his association with the investigation by the FBI, US Army CID and SFPD resulted in the arrest of Hambright. October 20, 1987, is the date Dietrich got off a fucking bus at MCRD San Diego, CA to report for recruit training after a year of "delayed enlistment".
That's right!

Dietrich enlisted in
Oakland, CA in October 1986! And spent a year in the Delayed Enlistment Program (DEP).
A major complication to his claim of actually assisting the authorities in their investigation.
1. He resided in Oakland and was not employed at the Presidio
2. He claimed involvement with Aquino from 1982
3. His involvement in the DEP toward his eventual USMC basic training
precluded any involvement with a Federal law enforcement investigation and would have immediately disqualified him from enlistment.4. His failure to complete USMC Basic Training and Entry Level Separation Discharge (ELS) in January 1988 is inconsistent with his claim.
