Moreno suffered a traumatic head injury at the Plaza de Benavente in Benavente, Zamora, Spain, in a fight between Hispanic nations in 1958. She was on her Arabian horse named "Moreno" and got into the last moments of the bullfight, when "Moreno" could not back away and was hit by the bull's charge, causing both Moreno and "Moreno" to crash into the side of the ring, with "Moreno" landing on her. She was rushed to La Milagrosa hospital. The injury fractured her skull, and she was comatose for 25 days. After coming round, she was advised by doctors to stop fighting, which she chose to do, wanting to recover. She has mentioned that it reminded her of her first injury in Peru, which made her lose fear in the bullring. She has suggested that her agent at the time shouldn't have taken the contract, because the bullring was so small, but once it had been accepted they couldn't cancel. After Moreno's death, her daughter María Esperanza began collecting documents of her legacy, and received a letter from Pilar Huerga Mielgo in Benavente, who said that "many of those who attended that bullfight thought, and ran into the square convinced, that that young girl "of the big, beautiful eyes" had fatefully died, due to the seriousness of the accident." Moreno's recovery took several months, which was mostly spent in a specialist center for toreros in Madrid, before she returned to Venezuela. She still suffered symptoms for many years after the injury, including partial memory loss and occasional paralysis on her right side. Initially, she could not even walk and struggled with simple things, and she thanks God for her safety. She suffered the injury after living in Spain for six years, and returned to Venezuela to start a family. Moreno says that after leaving, whenever she was in Venezuela, she tried to see her family. She has also said that her career made it impossible to have a relationship, though she dated a little. She says that she dated a famous singer in Mexico who became very obsessive and possessive, causing her to flee first to her mother's house, and then back to Europe. When she returned to Venezuela, she had a large family. She has publicly criticised the Running of the Bulls in Pamplona. Sources suggest she also co-starred in the 1957 Brazilian Western film .
