Laura Day

Five?

Yeah.

Well, if you...

You're not supposed to count the annulment, right?

And then the one in Mexico didn't really count because I was told we needed to register it here in the United States, and we never did.

For more than a decade, between husbands four and five, Laura manages to stay out of trouble with the law.

But now, in October 2012, all that is about to change again.

You came today for what reason?

When a witness comes forward saying he was on the beach with Laura on the day that Taylor drowned.

Tell me exactly what you saw.

Dad, our smile was familiar to you.

Six-year-old Taylor Searing has drowned after spending an afternoon on the beach with a stepmom, Laura Day.

You have this loving mother who just lost her six-year-old child.

All I could do was just lay my head on my son's... and just cry.

He was gone?

Mm-hmm.

It's etched in my mind very vividly.

It haunted me and continues to.

My name is Detective Pena and I'm with the Corpus Christi Police Department and I work with the Crimes Against Children Unit.

Laura has been interviewed by the Corpus Christi Police, but despite being allowed to return home, the investigators still have suspicions about her.
