Boston (CNN) -- Government prosecutors have released a series of new photographs showing cash, weapons and even a grenade recovered from the Santa Monica, California, apartment where fugitive James "Whitey" Bulger and his long-time companion, Catherine Greig, apparently lived for 15 years while he was being hunted by the FBI. 

The photographs were introduced as evidence Monday during a detention hearing for Greig, whose court-appointed attorney is seeking to have her released on bail. FBI Agent Michael Carazza testified that agents found 30 weapons inside the apartment, some of them hidden behind living room and bathroom walls. 

The evidence photographs show several handguns, one automatic rifle and a hand grenade the FBI says was recovered after it arrested Bulger in late June at the small apartment only a few blocks from the beach. 

The government also released a brief security camera video of Greig walking in and out of a local drugstore, picking up a prescription, prosecutors said, that was under an assumed name. Bulger and Greig were known in Santa Monica as Charles and Carol Gasko. 

One neighbor, 88-year-old Catalina Schlank, told CNN that the couple was always friendly to her. But, she added, they refused to be listed as an emergency contact in the event Schlank became ill, and the only phone number they provided was one that was directed to an answering service. 

The detention hearing was to determine whether Greig will be granted bail on charges of harboring a fugitive. During the hearing, her attorney, Kevin Reddington, told the judge that his client was a "kind, gentle person" who had a "loving personality." For his part, Bulger had entered a plea of not guilty to 19 counts of murder.
