I am looking for information on this oil painting.?

I bought it at an auction in the SFO bay area. They claimed it came out of a museum in San Jose that shut down years ago. The artist name is in the r/h lower corner and is printed "Giorigo" . It has the appearance of an Aztec warrior holding a dead maiden horizontally in his arms. colors are vibrant. If needed I can send a picture of it. Thanks Mike
