Miguel Ruiz Lobo slashed an 11-year-old Martha Guzman's throat in Little Havana in Miami, Florida on June 22, 2022 and staged it to look like suicide after she convinced her mother to break up with him. Miguel Ruiz Lobo was the former live-in boyfriend of Martha Guzman's mother. The girl was found with cuts to her neck and wrists and rushed to hospital, but she did not survive. Police said that Ruiz had fresh scratches to his face and arms, and DNA taken from beneath the girl's fingernails showed his DNA, revealing she had put up a fight against her attacker. Ruiz is charged with first-degree murder.
