Peralta stated that Cisneros had attempted suicide at approximately 19 years of age and had been diagnosed with a mental health condition.

“I think bipolar, but I don’t know what else was going on,” he stated, emphasizing that she received monthly injections as part of her treatment.

“I think maybe she stopped the injection she was getting and that caused her to act the way she was.”

Peralta mentioned that the last occasion he saw his distressed sister was in August during their stepfather's birthday celebration. He noted that she frequently visited their mother, but had recently ceased these visits.

“There was no sign something was wrong,” he remarked. “Last week she stopped coming to see my mother. We called, she said she was fine on Saturday.”
