A murder trial began Tuesday for a Dallas woman accused of injecting industrial-grade silicone into women's backsides in a series of amateur cosmetic surgeries.

Denise Rochelle "Wee Wee" Ross, 45, was known for giving women the "Wee Wee Booty," a prosecutor said.

She is accused of administering fatal butt injections to Wykesha Reid, 34, who was found dead on Feb. 19, 2015, at a salon in the 3800 block of East Side Avenue near Deep Ellum.

Reid died after the silicone caulk entered her veins, traveled through her heart and was trapped in her lungs.

Police found Reid lying on a table in a mostly empty building that housed the makeshift salon. She was clearly dead, an officer testified Tuesday.

"They left Wykesha Reid's body on that massage table," prosecutor Summer Elmazi said. "They left her there like a piece of garbage."

Police were called to the building by Jimmy Joe "Alicia" Clarke, 33, who is also charged with murder in the case. Clarke's trial is set for June.

The pair is also charged with practicing medicine without a license.

Defense attorney Heath Harris said in opening statements that there is no proof that Ross was the one who gave Reid the silicone injection.

"It was Alicia that gave her the shots that led to her death, not Ms. Ross," Harris said.

He called Reid's death a "tragic, tragic, tragic accident."

He also emphasized that it was Clarke who was at the salon the day Reid's body was found, and it was Clarke who called 911.

But Elmazi said both Clarke and Ross performed the injections. She said women called Ross to set up the appointments, and her product was known as the "Wee Wee Booty."

The black-market butt injections were promoted by word of mouth, and Ross wouldn't give her clients an address to go to until the day of their appointment, Elmazi said.

She said Ross never told the women what she was using in the injections, occasionally even saying it was just saline.

"She never one single time ever told them she was injecting industrial-grade silicone into these women's bodies," Elmazi said.

The prosecutor said Ross didn't always disinfect the massage table that she asked clients to lie on for the injections and didn't always clean their skin. Once the injections were done, she would use super glue and cotton balls to seal the puncture wounds, authorities say.

But, Elmazi said, Ross cleaned the room after Reid died, leaving behind little evidence that either woman was even there.

Then she left Reid dead in the room, the prosecutor said.

Much of the testimony Tuesday revolved around the hours leading up to Reid's death and on Clarke, who called 911 to report Reid's body was found and who was there when a patrol officer arrived.

On the 911 call, Clarke sounded frantic.

"She's not moving," Clarke told the call taker. "She's hard. She's hard and cold."

Officer Jay Angelino described Clarke, who is transgender and identifies as a woman, as "calm" when he arrived at the salon.

He said Clarke told him that Reid had been sick the night before, and Clarke told the woman to go lie down. When Clarke came back in the morning, Reid was dead.

And the building appeared mostly empty, as if it weren't a working salon.

"There was no towels. There was no product," Angelino said. "There was no garbage can."

Reid was lying on her back on the table, her pants partially pulled down. Angelino said he could tell right away that she was dead.

Ross was arrested late Monday on a bond violation, and her attorney asked that state District Judge Tammy Kemp release her under electronic monitoring.

Kemp said she would think about it overnight and make a decision Wednesday morning, when the trial resumes. She hesitated, saying she isn't confident an ankle monitor would prevent Ross from conducting more cosmetic procedures.

The decision is not about the money, Kemp said.

"It's about the safety and security of the community."
