Dominguez, a 77-year-old opinion columnist who had worked as a journalist for nearly four decades, was stabbed 21 times, according to Mexican authorities. They said he was attacked by at least three men who remain unidentified and at large.
The killing Saturday afternoon underscores the lethal risks faced by journalists in Mexico and the growing wave of violence gripping the nation.
Officials said they were investigating to determine whether the attack was connected to Dominguez’s work. He wrote frequently about politics, organized crime and occasionally their intersection — a perilous beat in a country that was second only to war-torn Syria in the number of journalists killed last year.
Eleven journalists were slain across Mexico in 2017, with no culprits arrested in most of those cases. Dozens of reporters have fled the country or gone into hiding.
