Margarito Torres 1933 death registration La Blanca

Margarito Torres of La Blanca Zacatecas was my great grandfather. I found his death registration but I'm having a hard time reading it. I think this document contains other information that will help me trace back my ancestry further. I have attached the death registration and was wondering if any of you can help me read what it says. I thought his parents were Cristoval Torres and Teresa Morales, but I think this document says that they are his grandparents. Is that correct?

Thanks in advance!
