"I was there from the late 70's to early 80's. My job was to oversee the Medicare and Medicaid patients and make sure they got the appropriate medical care," said Riley, who is now 65 and living in Versailles, Mo.
"There was talk within the pediatrics unit in the hospital that there were a lot of babies dying," Riley said. "And the way the babies were dying was very unusual. Granted, these children were already sick because they were in the pediatric ICU. But they would suffer from these really untoward events."
"Things like an infant burn victim all of a sudden going into a respiratory attack. These kids would suddenly bleed out or go into cardiac arrest. Their causes of death were not related to their illnesses at all," Riley said.
Like Pendergraph, Riley also looked at the pediatric unit's medical records.
"Jones' name was listed next to most of the infant patients who had suddenly died," Riley said.
Today Kahan and McClellan are trying to find one of the parents whose child may have been killed by Jones.
A Facebook group called "Victims of Genene Anne Jones" has 38 members. Joann Garza, the group's administrator, had a twin brother her family believes was killed by Jones.
Garza's brother, Joel, was taken to Bexar County Hospital after he choked on his bottle. According to Garza, Jones gave shots to her brother and two unidentified twin girls. All three children died.
"We only have a few years left to do this," Kahan said. "We just need one person to come forward."
Jones is currently being held in the Carole S. Young Medical Facility, a correctional center in Dickinson, Texas. Batson could not say whether Jones was receiving medical care, but did say that the facility was reserved for inmates needing medical attention.
William Chenault, a San Antonio-based lawyer, briefly served as Jones' court-appointed attorney.
To this day Chenault cannot say if Jones was innocent or guilty, "but the case against her was based on circumstantial evidence."
"Jones was a very intelligent woman. She loved working at that hospital. She was a very good nurse. Some said the best," Chenault said.
At the suggestion of prosecuting lawyers, Jones was evaluated by a psychologist.
"She came back perfectly normal," Chenault said.
"Jones always denied that she did anything. She said she was there to help the kids."
As Jones' attorney, Chenault worried that Jones' need to defend herself ultimately hurt her case.
"Every time the press said something negative about her, she would hold a press conference to defend herself. That would just fan the flames. But she wouldn't listen to us. She kept saying she could handle it," the lawyer said.
Genene Jones did not respond to repeated requests for comment.
