"Even having our jobs, we still can't wrap our heads around this," he said. "A lot of people think that just because of our positions we can understand it, but we can't."
In court Friday morning, Wilson stood flanked by eight police officers as her lawyer, Tony Liker, clutching a Bible and a copy of the charging documents, asked the judge to postpone arraignment until Wednesday to give him time to meet with Wilson.
Wilson, who had been identified by police and prosecutors as Brenda Stokes, told the judge Friday that her full name was Brenda Stokes Wilson.
Jade's father, Philip Morris, was removed from court Wednesday by armed court officers after shouting questions about his daughter's whereabouts to Wilson. He did not attend Friday's hearing.
The two dated for several years, and Jade had a long and trusting relationship with Wilson, according to the girl's grandfather, Philip Tucker.
Tucker said Philip Morris lived in Billings, Mont., and worked at a Flying J truck stop for more than a year. He would stay with Wilson when he visited Las Vegas, Tucker said.
Authorities have not disclosed a motive for the slaying. But Tucker said Wilson appeared to believe that the face-slashing victim had become romantically involved with Philip Morris.
Wilson picked up Jade for their shopping expedition around 5 p.m. Later, she got a ride with a friend to the Bellagio. She allegedly attacked her co-worker, Joyce Rhone, at around 9:30 p.m.
Rhone, 44, was hospitalized with deep cuts on her face, including one from her ear to the edge of her mouth.
Wilson told investigators that she visited her doctor last week, seeking to be admitted to a hospital "due to feeling like she wanted to hurt someone."
