The man who, according to authorities, opened fire on Saturday at a shopping center near the Dallas, Texas as a result to kill eight peoplehad ties to neo-Nazi ideology and was a white supremacist, as his social media posts show.

American media reported that the man praised Hitler and wrote posts that targeted women and racial minorities.

Meanwhile, Texas State Police released the names of the five adults killed Saturday and confirmed that three children were among the dead: two girls, ages 11 and 8, and a 3-year-old boy.

Among the dead are Kio Song Cho, 37, his wife Cindy Cho, 35. According to media reports they were the parents of the 3-year-old boy who was also killed, with his 6-year-old brother being the only family member to survive.

The two girls who were killed were sisters. The remaining dead were Christian Lecour, 23, Elio Cumana-Rivas, 32, and a woman, Aisuaria Thatikonta, 26.

Another 10 people, aged between 5 and 61, have been injured, of which at least three are in critical condition.

The assailant, who used an AR-15 semi-automatic rifle, has been identified as 33-year-old Mauricio Gracia. He fell dead from the fire of the police who rushed to the scene.

Authorities have not yet released a possible motive for Saturday’s shooting at Allen Premium Outlets in the Dallas suburb of Allen.

Hitler and the “Far-Right Death Squad”

Police are investigating Garcia’s social media accounts and have found posts of him targeting minorities, NBC News reported.

At the time of the massacre, Garcia was also wearing a badge with the letters “RWDS” (Right Wing Death Squad).

The newspaper New York Times wrote that the attacker was believed to have made several posts on a Russian social networking platform in which he praised Hitler and expressed neo-Nazi views.

At the moment the authorities have not commented on these reports.

The massacre is one of the most recent on record in the US this year, with the non-governmental organization Gun Violence Archive reporting at least 202 mass shootings in which four or more people have been killed or injured.

In a surprise move, a Texas House committee on Monday approved a bill that would raise the minimum legal age to purchase some semi-automatic rifles to 21 from 18.

The measure was proposed by Democratic Rep. Tracy King, but is not expected to be approved by both houses of the Republican-majority Texas legislature, nor by Gov. Greg Abbott.
