Stephen McCausland, Public Safety Spokesman, said an autopsy is standard procedure with children deaths under the age of three.

Additional testing will need to be done to determine the cause of death, said the State Medical Examiner’s Office. 16-month-old Travis Weston had been placed at the center as a foster child on March 2 by the Maine Department of Health and Human Services.

The boy was on medication for an ear infection and had been ill for several weeks. Tuesday morning he was placed in a crib for a nap. Around 2:30 p.m., he was unresponsive at the Peek-A-Rroo Day Care Center. Family members tried to revive Weston, but were unsuccessful, said McCausland.

Teresa and Kent Sadak own the day care and were serving as foster parents for the baby. The Sadak’s have been fully cooperative with investigators.
