Baby Kate has been missing since June 29th 2011. An Amber Alert issued wasn't issued in a timely manner. She was reported missing around 1:15pm EST and the Amber Alert wasn't issued until nearly 9 hours later. Kates bio father was arrested approximately 4 hours after she was reported missing but Kate wasn't with him and he claims that he didn't have Kate and in fact said that her Bio mom had her.
Extensive ground searches near the bio dad's home were conducted and nothing was found to lead LE to where Kate is.
It was reported in open court that both parents at some point discussed giving Kate up for adoption. While there is no indication that a legal adoption has taken place, it is suspected that Kate may have been given to someone outside of the family to raise her.
Ariel Courtland has maintained that Sean is the last one to have physical custody of Kate when she went missing. As well Sean Phillips has maintained that he is innocent of kidnapping and has refused to reveal publicly any other information and he remains in police custody.
