San Francisco Police on Monday provided KTVU with an exclusive look at the weapons and ammunition that were found inside a homeless man's vehicle near Golden Gate Park when he was arrested on July 21st.
Neighbors told KTVU the suspect's jeep was parked on Waller Street close to the park for more than two months.
They said they were shocked to learn the man who lived in the vehicle is accused of stockpiling weapons and ammunition.
37-year-old Robert Clinton Johns is now behind bars, facing four felony weapons and drug charges.
Law enforcement shared photos of what was discovered inside the suspect's jeep when they arrested him July 21st.
His arsenal included 5,800 rounds of ammunition, a sawed off shotgun, a 9 millimeter handgun and a cache of knives. He also had marijuana and $900 dollars in cash.
"We're going to do everything we can to handle this case appropriately so this individual won't be on the streets," said San Francisco District Attorney George Gascon.
The District Attorney said investigators were still trying to find out how Johns obtained his arsenal.
He first came to the police's attention last month when neighbors complained that he harassed and threatened them.
"He liked to say that he was a Special Ops guy and there were people who tried to engage him," said one area man who did not want to reveal his identity.
Police said during their first encounter with Johns, he allowed them to search his vehicle. At that time, they found and confiscated a loaded shotgun and 22-caliber rifle.
He was taken to the hospital for psychiatric evaluation and later released.
Investigators want to know how johns obtained more ammunition and weapons in the three weeks between the two times they had contact with.
Police credit alert neighbors for keeping johns off the street.
"We have a great working relationship with the community and they didn't hesitate to let us know what was going on," said SF Police Lt. Alexa O'Brien.
In a police report, one officer wrote "Johns may be preparing to engage in some violent act of unknown dimension."
Police told KTVU they are still gathering evidence and investigating who Johns is. One listed address for Johns is in Reno.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
