Anyone been to cronin house in Hayward ca?

i have been there before. The house that is all borded up. About two and a half years ago. My friends and i wanted to see if it was haunted. We went inside and it was dark and mad creepy. There were some stairs we had to walk up. There must have been maybe a flite of six steps, and right when we got to the top the door slammed shut. This door took two really built guys plus two girls to open. it was hanging by a henge and would have been impossible for one person to slam shut. once that happened we immediately ran out. we were scared shitless. long story short i have been doing research and still its a mystery.
