A distraught fiance pleading for the return of his two-week-old baby girl, Margot,

Crime stories with Nancy Grace.

Shane Carey is pleading for help finding his newborn daughter, Margot, and her mother,

Heidi Brissard. This photo shows Brissard dropping off her son at school at around 7.30

Thursday morning. According to Austin Police, it was the last place she was seen.

I went to work and I talked to her 8 o'clock and it's last time what's up to her.

Shane says when he got back home from work at two-thirds day, she and the baby were nowhere to be

found. He tells us when his son's school called asking for someone to pick up the boy,
