ORIGINAL STORY: Justin DiPeitro is going to be served...one way or another.

According to WABI, legal notices will be posted for three Fridays in the Morning Sentinel and in newspapers in California as an alternative way to serve DiPeitro in the wrongful death lawsuit that has been filed against him in the disappearance of his 20-month-old daughter Ayla Reynolds from the family home in Waterville on December 17, 2011. DiPeitro, who now lives in California, has not found to serve the paper in person, and they have been trying!

According to the SunJournal.com, DiPeitro has 41 days to answer.  If he does not answer, the wrongful death suit, a civil case, will move ahead and this will give the lawyer for Ayla's mother, Trista, the opportunity to move ahead and depose witnesses.

They will also continue to try and find him. What happens if they don't find him and he does not answer? This is what the SunJournal.com story had to say:

The court order, signed by Cumberland County Superior Court justice Thomas D. Warren,  says DiPietro must file an answer to the order with the court within 41 days after the first publication in the newspaper.

“Failure to serve an answer will cause judgment by default to be entered, granting relief sought in the motion or complaint,” it says.

Interesting. So what we know for sure is:

-The Maine State Police have stated they believe Ayla is dead.
-The courts have declared Ayla is dead.
-Her body has not been found.
-No criminal charges have been filed in the case.

We shall now wait and see...
