The independent journalist and political columnist for El Diario de Nuevo Laredo since 2016 was shot dead in the city of Nuevo Laredo, Tamaulipas state. The city is considered one of the most dangerous places in Mexico, reports said. In his last column, Dominquez had denounced the impunity for crime over the last 18 years in Mexico during which those behind the killings had never been identified.

According to the Sindicato Nacional de Redactores de la Prensa (SNRP), an IFJ affiliate, Dominquez was the first killed journalist to be killed since the start of 2018.
