Remembering Isabel Martin

What should have been a week of preparation for Brandon Martin and Monica Delgadillo's daughter's birthday has turned into plans for the young girl's funeral.

"The image is burning in my brain of her right there," Brandon Martin, who is also the suspect's brother, said.

Isabel's parents said she was killed after her own uncle opened fire on another man that he had an altercation on Tuesday night at the Marina Vista community.

"She's innocent, sweet. She never did anything wrong to nobody, very happy," her mother told ABC10 Wednesday.

Her parents said Isabel dreamed of being a blogger. Despite sometimes getting bullied in school, the family said she always made new friends. She leaves behind a two-year-old brother. 

The family said they are now homeless and have started a GoFundMe to help lay Isabel to rest.
