Villarreal’s mother – Lydia Villarreal – was there when her son was killed. She said her son was not suicidal, and she will never forget what happened that day.

“I can't sleep at night because I was here,” Lydia Villarreal said. “My son was shot more than 30 times - his body was massacred."

Lee Roy Villarreal was killed following a standoff last month after police say he appeared to be armed and was heading toward officers in an “aggressive” manner before police opened fire at him.

Lydia Villarreal showed Channel 5 News video of the incident taken by a neighbor where the sound of several gunshots can be heard.

“He had no teeth, he had no eyeballs, everything,” Lydia Villarreal said. “All the bullets came from behind."

Lydia Villarreal said her son didn't have a history of mental health issues.

“I was here and I felt I could've stopped it,” Lydia Villarreal said. “I just wanted to just stop it and I have to relive the moment, and I have to live through this."

Now, she's hoping for justice.

“I just don't want this to happen again,” Lydia Villarreal said. “I feel they should have done more – they should've done more."

Channel 5 News reached out to Edinburg police and the Texas Rangers. Both departments said they could not comment due to the ongoing investigation.
