"I was shocked and I expected something like this to come up again in the future. I wasn't necessarily sure how long it would take," said Lubin. "I never expected it to be the same exact scenario."
It happened four years ago in California. Dillard was convicted of giving the couple's son, then 10 months old, morphine. But now she is facing similar charges in Washington County, Oregon. That's where she appeared in a courtroom Thursday and entered a plea of not guilty.
Detectives say she took her 2-month-old girl to St.Vincent's Hospital up in Beaverton in June, saying she had a fever.
"She did try to contact the father to come to the hospital at that point, but he was not willing to come," said Sgt. David Thompson from the Washington County Sheriff's Office.
A nurse found the girl the next morning, barely breathing. Investigators believe Dillard injected the child with morphine.
The suspect's family says she suffers from the condition Munchausen syndrome and MBPS. Aside from making her child sick, she would also make herself sick to get attention.
Neighbors say they never suspected that of the new mother.
"She seemed like a normal everyday person. It is shocking. I would never suspect anyone to do this -- especially a mother," said neighbor Edward Lara.
Lubin says he doesn't completely buy the Munchausen's defense for his ex.
"Me personally I think it is just an excuse for somebody to do something bad and terrible," said Lubin.
Lubin says he feels safe now that Dillard is locked up.
"I spent four years now every night making sure all of my doors and windows were locked. Even though I talk to her once in awhile, one day she may come back down," said Lubin. "For the first time in the last week I actually feel comfortable going to bed at nighttime knowing that nothing is going to happen to my son."
Dillard is behind bars in Washington County and her little girl is in state custody.
