Journalist Alicia Diaz Gonzalez was found dead on Thursday at her home in Monterrey, northern Mexico, having apparently been severely beaten.
Diaz Gonzalez "was on the floor, face down, in a pool of blood having suffered blows," a source from the Nuevo Leon state prosecutor's office told AFP news agency on condition of anonymity.
The attack took place between 8:00am (13:00GMT) and 10:00am (15:00GMT) local time on Thursday in Colonia Paseo Residencial in Monterrey.
