A journalist, his wife, and their 21-year-old son were shot to death inside their home in this Gulf coast city Monday, authorities said.
Journalist Miguel Angel Lopez Velasco and his family were shot with a 9 mm handgun, said Veracruz state prosecutor Jorge Yunis.
Lopez Velasco wrote a column about politics and crime and was editorial director for the daily newspaper Notiver. His son had been working as a photographer for the same newspaper.
Yunis said investigators haven't determined a motive in the killings and no one has been arrested.
Earlier this month, state police in Veracruz found the body of reporter Noel Lopez in a clandestine grave. He had been missing since March. The two reporters are not related.
Police said Noel Lopez died of a blow to the head and that soldiers found his body after a man they arrested in the killings of several police officers confessed to killing him and led them to the body.
Noel Lopez worked for the weeklies Horizonte and Noticias de Acayucan and for the daily newspaper La Verdad.
Press freedom groups say Mexico is the most dangerous country in the Americas for journalists. More than 60 reporters have been killed in Mexico since 2000, according to the National Human Rights Commission.
