WACO, Texas (FOX 44) – UPDATE: The suspect arrested in the Waco capital murder investigation has been identified, along with the victims.

25-year-old Matias Maltos-Saucedo has been charged with Capital Murder after fatally stabbing his mother, 59-year-old Felipa Martinez, and stepfather, 70-year-old Antonio Martinez.

This is Waco’s second murder investigation of 2023 – but the first and second murders in 2023, according to police. This is because the victim of the first murder investigation of 2023 was killed in 2022.

Maltos-Saucedo was taken into custody when officers responded to the 2100 block of Clay Avenue at approximately 7:15 p.m. Sunday to a call of an assault in progress. When officers arrived, they found Felipa unconscious and covered in blood. Maltos-Saucedo was on scene when officers arrived.

Officers immediately started life-saving measures on Felipa until she was transported to Hillcrest hospital by AMR. Her wounds were too severe, and she was later pronounced dead. Officers also found Antonio, who was pronounced dead on scene.

This investigation is ongoing. FOX 44 News will have more information as it becomes available.
