For years people have claimed to have heard screams or seen strange things moving in the Columbarium in San Francisco, a repository for human ashes that is also home to some of the city's founder.
The copper-domed Columbarium holds the remains and memorials of some of the city's most prominent figures including Harvey Milk.
Paranormal researcher Patrick Doyle goes inside San Francisco's Columbarium, home of some of the city's founders, to search for the unseen. He shows us what is really there and what our mind thinks is there.
The Columbarium is located at 1 Loraine Court, near the intersection of Stanyan and Anza Streets, near Golden Gate Park and it is open to the public.
