Andria Gaither, assistant manger at the mall’s Tommy Hilfiger, said she was devastated to learn the day after running for her life when shots rang out that one of the dead was Christian LaCour, a 20-year-old security guard who previously worked at the clothing store and often stopped in to chat.

Just a few nights earlier, she had called LaCour when a customer wanted in after hours. He came and asked the man to leave, and then offered a security escort to her and two teenage employees.

“He wanted us to feel safe,” Gaither said.

“I’m just in shock,” she added. “He was very young, very sweet, came in all the time to visit with us.”

Also killed was Aishwarya Thatikonda, 26, who was from India, held a graduate degree in construction management and worked as a civil engineer at a the Dallas-area firm Perfect General Contractors.

She was “always prepared to give her very best,” company founder Srinivas Chaluvadi said via email.

He said her parents live in Hyderabad, India, where her father is a judge.

“She came to the United States with a dream to make a career, build a family, own a home and live forever in Dallas,” Chaluvadi said.

Chaluvadi said Thatikonda would have turned 27 next week and she had become like like family: “She attended birthday parties at my home, we celebrated festivals together and we had family dinners.”

DPS has identified the eighth victim as Elio Cumana-Rivas, 32.

Authorities are still trying to piece together what led to the attack, which ended when the suspected gunman — 33-year-old Mauricio Garcia — was fatally shot by police.

Federal officials are looking into whether Garcia expressed an interest in white supremacist ideology, a law enforcement official told The Associated Press. The official cautioned that the investigation is in its early stages.

Federal agents have been reviewing social media accounts they believe Garcia used, as well as posts that expressed interest in white supremacist and neo-Nazi views, said the official, who could not discuss details of the investigation publicly and spoke to the AP on condition of anonymity.
