Could sense. selena was experiencing more than preteen growing pains. she was definitely just a different child. she became very dark. she started cutting her hair and having eating disorders. reporter: you ve probably, i assume, tried to take her phone from her? yes. one time her phone had died actually in the van and i was driving and i wouldn t give her mine, so she grabbed my arm here and this she squeezed it so hard while i was driving, this was all black and blue. she didn t care about how she was going to hurt us. she had to get it back from us. she had broke destiny s nose. you know this is your child, but at the same time it s not your child. like a dr. jekyll and mr. hyde type thing.
