>> what was your last conversation with her?
>> it was a brief conversation on friday evening. we talk every day. and we just spoke like we normally speak. i didn't sense anything in her voice that led me to believe that there was a problem or anything. and i said, okay, baby, good night and i'll talk to you tomorrow. i said i love you and i'll talk to you tomorrow.
>> i'm sorry. go ahead.
>> i was going to say, but when the next day came, i didn't get to speak to her. i did not get to hear her voice. her phone was going to voicemail all day and that's when i knew something was definitely wrong.

>> she is, terrilynn has always had a passion for teaching. it was something that she always wanted to do even when she was in second grade. she wanted to be a teacher and she has impacted those kids. she's brought their test scores up. she's been unremarkable to say that she's only been teaching a year and a half. it will be two years in may that she's been teaching. in that length of time, she's been unremarkable. unremarkable. i'm so, so proud of my daughter and i feel that it is not over yet. she has to accomplish more. that's why she has to continue doing what she's doing and that is to teach them.
>> do keep us posted.
