JACKSONVILLE, FLORIDA: The family of Kellan and Aurora Starr is devastated after their twin daughters, 4, were found unresponsive on August 25 and later declared dead.

The mother of the twins has claimed they died after getting trapped in a wooden toy chest at their Jacksonville, Florida home.

Though Jacksonville Sheriff’s Office deputies jumped into action and made several "attempts to revive them, they were pronounced deceased," as per police.

The sheriff’s office updated on the incident and said the investigation is still in a "very early stage," but as per the available information "both children were playing in the home and when checked on, both were found unresponsive."

"We are working with our partners at the Medical Examiner’s Office to determine the cause of death," police further said.

"At this time, we don’t know if this is an accident or if foul play is involved.”

Mother Sadie Myers shared over Facebook that her children were put to bed by their father, and then he went to sleep himself.

“When I got home from work a couple hours later I looked in at all the kids like usual to make sure they were sleeping, then ate my dinner and went to sleep,” Myers posted.

“At some point early that morning the twins woke each other up and decided they wanted to play in their room rather than sleep,” reports People.

"They do this a lot," Myers explained. "And then they usually fall asleep in some weird place in their room with toys left everywhere so mom and dad can see proof of their late night playing when we get up in the morning… Friday night the weird place they decided to snuggle up and go back to sleep was in their cedar toy chest that we use to store all their stuffed animals."

She suggested, “Sometimes during their sleep one of them must have moved or kicked during a dream and it caused the lid of this old wooden cedar chest to close."

Please throw away such toy boxes!

"Something I did not know and I’m sure many others don’t know is that most wooden toy chests once closed are AIR TIGHT and also sound proof," she shared. "So as they slept, all snuggled up together, they slowly ran out of oxygen."

The broken mother warned other parents, saying, "I hope if you have a toy box like this that you destroy it immediately!!! Please keep me and my family in your hearts and prayers."
