Deputies responded a short while later and found the suspect outside near the garage, according to the affidavit. Martinez-Ruiz was detained, and the affidavit stated he was saying suicidal things.

Martinez-Ruiz was taken to the hospital because he began vomiting blood and had injuries to his hands.

Afterward, the caller and his mother led deputies to a shed near the home where Fernandez-Olveda’s body was found with multiple stab wounds, according to the affidavit. He was pronounced dead on scene.

The caller and mom told deputies Martinez-Ruiz had recently lost his job and apartment, and Fernandez-Olveda allowed him to live with them at the house since May 28. They described Martinez-Ruiz as polite but was recently acting strange and was paranoid due to drug use.

By Sunday, May 30, the family asked Martinez-Ruiz to find another place to live, the affidavit said. Fernandez-Olveda continued to help him, but Martinez-Ruiz’s paranoia escalated into him reportedly stabbing Fernandez-Olveda, according to the family, because he believed Fernandez-Olveda wanted to harm him.

KXAN has reached out to Martinez-Ruiz’s attorney for comment. We will update this story once we hear back.
