(NECN: Amy Sinclair) - The father of missing Maine toddler Ayla Reynolds, Justin DiPietro of Waterville, is back behind bars, this time for violating bail conditions that were set following his arrest on a domestic assault charge in July.
DiPietro was charged with assaulting his ex-girlfriend, Courtney Roberts, who was with DiPietro the night Ayla went missing.
Ayla's mother, Trista Reynolds, is now preparing to release what she calls "horrific evidence" related to her daughter's disappearance.
Twenty-month-old Ayla went missing on December 17, 2011 while staying in DiPietro's Waterville home.
Police have said they believe foul play was involved and that she was not kidnapped.
No one has ever been charged.
In hopes of moving the investigation forward, Reynolds is planning a press conference for September 25, the day DiPietro will be in court on the domestic violence charge, to unveil evidence she says police shared with her last January.
"With what was shown to me, I don't see how any child can be alive after that, said Trista Reynolds in tears. "All I can picture when I close my eyes is the blood that I saw."
While Reynolds won't elaborate until the press conference, she says state police told her Ayla's blood and saliva were found in multiple places around DiPietro's bedroom and that Ayla's blood was also discovered in his truck.
She says she doesn't believe he intentionally murdered their daughter that December night, but that something happened and he panicked.
"In my eyes, by letting it go so long and not getting help, he killed her," said Reynolds.
Reynolds says she hopes this information will lead to prosecution.
"I understand she's frustrated. Sometimes we're frustrated too," says state police spokesman Steve McCausland. "But we're as committed to the case now as we were day one."
McCausland would not comment on the veracity of the evidence Reynolds plans to share, saying only that she has the right to say what she wants to about her daughter's case.
Reynolds says she hopes going public with the evidence will also encourage DiPietro, who's currently being held at the Cumberland County Jail, to do some soul searching.
"I'm hoping by him sitting in jail now, it might get him thinking and start to eat him alive," said Reynolds.
What she hopes for most of all is to know exactly what happened to her daughter.
"I think maybe today is the day, but it never is that day," said Reynolds.
Until that day comes, Reynolds says she will continue to seek justice for Ayla.
Reynolds plans to publish the new information on two websites on September 24, the day before her press conference.
