WINDSOR, Colo. (CBS4)– An unlicensed day care in Windsor is the subject of an investigation after a baby died while being cared for there. Police are investigating the case as a possible incident of shaken baby syndrome.

Leyton Haggard spent the last three weeks of his short life inside Children’s Hospital. He died early Thursday morning.

Police in Windsor said Trina Loucks has been operating an unlicensed day care out of a home in Windsor. Among the children was 7-month-old Leyton.

Someone from that home called 911 on March 21 to report the baby boy was unresponsive.

“They had requested medical assistance because the 7-month-old was having difficulty breathing,” said Windsor Police Lt. Richard Higuera.

Leyton was airlifted to Children’s Hospital. Doctors determined that his injuries were consistent with shaken baby syndrome.

Police have launched an investigation into possible child abuse charges against his caregiver.

“We begin looking into is it a case of shaken baby or something of that sort?” said Higuera. “We have to look at everything and we have to be thorough and complete.”

CBS4 knocked on the door of the day care but no one there was interested in speaking about the incident.

Police said Loucks, 36, was caring for her own two children plus three more, including Leyton.

Colorado’s Department of Human Services requires a license for anyone providing care for more than two unrelated children.

When asked why charges haven’t been filed, Higuera replied, “It’s an ongoing investigation. We are working in conjunction with the Department of Human Services and the coroner’s office and completing the investigation before we make a determination.”
