TMZ broke the story ... Baez has already been hired by a woman named Shirley Wygal -- whose 32-year-old daughter was shot and killed by Holmes.
Now, Weaver says, "I felt that the night of the incident, that the security at the theatre was lacking from the time I entered. I want answers, we ALL want answers. And I know Attorney Baez will do what ever he can to help with the fullest extent of the law."
He adds, "Every day, early in the morning or at night, I have a movie in my head of what happened. I wake up every night with nightmares. I don't think it will ever go away."
