DURANT, Okla. (KXII) -- The 911 call came in around 3 a.m.
"Officers were called to a residence where an infant was believed to be deceased," said Durant Police Detective Buddy Faulkner.
Faulkner said they were dispatched to a home near Sixth Avenue.
"The investigation is still on going so the cause of death has not been determined," said Faulkner. "Unfortunately, there are several cases a year where we work infant related deaths."
One possible cause police are looking at: co sleeping. Which is when adults share the same bed with their baby, which might sound harmless but Faulkner said could be fatal.
"It could be something as small as an arm or a finger or something for a very limited time that could obstruct their breathing and could cause serious or fatal injuries to a child," Faulkner said. "Co-sleeping is not something that is safe regardless of how many people say they do it without problems. It only takes one time to make the situation a bad situation."
"The thing I always tell them don't put them in bed with you," said neighbors Rick and Charlene Vanwest.
The Vanwests live nearby the home where it happened and tell their kids and grand kids it's too risky to sleep next to an infant.
"I think babies shouldn't sleep with you even when you're breast feeding," said the Vanwests. "You know breast feed then put them back in their own spot."
No names have been released and police say it's early in their investigation.
"My heart goes out to them I couldn't imagine what they must be going through," said the Vanwests. "We're so sorry about that and we pray for the them and we pray god will comfort them through this time of tragedy."
Durant Police said the baby's body has been sent to the medical examiner's office to determine the cause of death.
