A child is now fighting for his life in a Lexington hospital and police are trying to figure out how the toddler was hurt in the first place.
Paramedics were called to the home on Lexington's Allante Brook Court, just after midnight on Wednesday.
Family members say the two-year-old boy was coughing up blood and unconscious.
An aunt of the boy told 27 NEWSFIRST the boy spent some time with his mother's family in Cynthiana this past weekend and thinks that could be where the injuries happened.
Police say they have several people to interview and medical exams to complete before they figure out what hurt the child.
One theory was that the little boy fell, but his aunt says that couldn't be true. She says he was an active child.
We're told the toddler suffered a fractured skull.
So far, no charges have been filed.
