UPDATE: Newborn killed in Sleeping Bear Dunes National Lakeshore campground, authorities allege

BENZIE COUNTY, MI -- An 18-year-old Illinois woman is being charged with homicide after she gave birth in a campsite tent, then fatally injured the child, state police said.

Alyce Morales, of Cicero, Ill., is expected to be arraigned on an open murder charge, police said.

Morales' parents did not know she was pregnant, police said.

An autopsy showed the child died of blunt force trauma, said state police Sgt. Scott Bates of the Cadillac post.

Bates said the 18-year-old was vacationing with her parents at a campsite when she gave birth sometime after 11 p.m. on July 22. She had told her parents she wasn't feeling well and apparently went to the family's tent, where she gave birth.

Some time later, her father walked into the tent and found the baby. He called 911, police said.

The child, a girl, already had been injured when the father made the discovery. The infant, named Marie Morales, was taken to Munson Medical Center but died the following morning.

A judge on Thursday, July 25, ordered Morales held in jail without bond.
