Marion county officers are at a standstill in their investigation into the death of an infant over the weekend.
It's up to a state forensics expert to say whether charges will be filed.
Little Colin Russell had apparently been sick leading up to the moment on Saturday when he was rushed to Grandview Medical Center, who sent him immediately to Vanderbilt Hospital in Nashville.
The three month old boy lived here on Sequatchie Lane with his mother and her finance.
SHERIFF "BO" BURNETT, MARION COUNTY "On the 17th of this month, the ambulance was dispatched to the resident there in Sequatchie..a child not breathing." "I had a Detective assigned to the case.
She did go to Vanderbilt and a doctor there told her that the child had trauma to the brain..unconscious all week."
The baby died on Saturday night.
The sheriff says it too early for much speculation over what caused Colin's death.
But he has said all along that "its suspicious."
SHERIFF "BO" BURNETT "An autopsy was performed on the child yesterday there is Nashville..and we're waiting on the results from that."
The sheriff says there were no more children in the home, and that his officers have interviewed both parents, identified as Leah Collins and Chris Russell.
One of those neighbors said no one seemed to know the couple very well, but she had witnessed arguments between the parents in the yard.
When will the autopsy be completed?
SHERIFF "BO" BURNETT "Some you can get back pretty soon..some of it takes weeks..I hope we get something back pretty soon...but I don't expect it."
Until that information is available no one will discuss the case. The sheriff says if the evidence does incriminate anyone---
SHERIFF "BO" BURNETT "We might end up charging somebody soon, or we may take it to the grand jury."
The next grand jury session in Marion county is about two months away.
