ST. CLOUD, Fla. -- A Local 6 investigation reveals evidence indicating some baby deaths at a neighborhood daycare could have been prevented.

Four-month-old Dylan Hogue died on Jan. 7. He was the third baby to die in the care of Lynne Mulvaney, Local 6's Tony Pipitone reported.

Dylan's mother, Jennifer, said her husband dropped off her son at Mulvaney's St. Cloud home for daycare before his death.

"I didn't want to wake (Dylan) up, so I just kissed him goodbye," Hogue said.

Hogue's son died that day after apparently being placed on his stomach in soft bedding.

In 1989, another 2-month-old wound up belly down on a water bed, Pipitone reported. The official cause of the child's death was sudden infant death syndrome.

Five years later, Bryce Cunningham, 2-months-old, was also belly down on a water bed. The official cause of his death was sudden infant death syndrome, the medical examiner said.

The medical examiner's successor, Dr. Jan Garavaglia, said the deaths are not from SIDS, Pipitone reported.

"You would not classify that as a SIDS," Garavaglia said.

"And why is that?" Pipitone asked.

"Because the chance of having two SIDS makes it suspicious that something else is going on," Garavaglia said. "I doubt this is happenstance. I doubt we got three kids who are genetically predisposed. There is something else going on. All three of these children had unsafe sleep practices."

All of the babies were placed on their bellies on soft bedding, Pipitone reported.

Had the baby sitter been licensed by the state, she would have been taught that babies should be placed on their backs to sleep, Pipitone said.

"I don't think (Mulvaney) intentionally sought to hurt (Dylan)," Hogue said. "But she can't say she wasn't negligent where she placed him and how she placed him."

Hogue also said she does not excuse the Department of Children and Families.

"This is an extremely tragic outcome," DCF representative Carrie Hoeppner said.

"These kids are dead," Pipitone said.

"Yes, it is an extremely sad situation and we are glad to know about the situation now," Hoeppner said.

But the state has known about Mulvaney for years, Pipitone reported.

In 2006, DCF verified abuse by Mulvaney for harsh discipline on a 4-year-old she babysat.

She denied running a daycare home and DCF agreed, Pipitone reported.

"In that case there was nothing presented to an investigator that would present red flags," Hoeppner said. "Two deaths are obviously a red flag. But, if they are not attributed to abuse and we don't know about them, we can't really factor that into the investigation."

"We would never have taken (Dylan) there if we knew anything like we know now," Hogue said.

Mulvaney would not comment on the story, Pipitone reported.

The Hogues are expecting a new son soon.

"We are happy about being able to have a new baby but Dylan never should have been taken away from us," Hogue said.

St. Cloud police said they are waiting for more lab results before deciding how to classify Dylan's death. It is now classified as undetermined.

Mulvaney was charged with running an unlicensed daycare.
