Two Michigan teens may face charges after they allegedly used a baseball bat in an attempt to abort a fetus.

Police said a 16-year-old girl became pregnant and had a miscarriage in October at her home, outside of Detroit.

After an investigation, Michigan State Police determined that before the miscarriage, the girl and a 16-year-old boy -- the father of the unborn child -- may have attempted to abort the fetus.

"Without getting graphic, it involved a baseball bat and at some point the child was miscarried and that brings us to where we're at now," said Macomb County Prosecutor Eric Smith.

Smith said the male youth would hit the pregnant teen in the abdomen with a decorative-type wooden baseball bat every other day for three weeks.

"The length at which these two 16-year-olds went to abort this unborn child is just disturbing," said Smith.

Police were also investigating to determine if the parents of the two teens would face charges after they apparently decided to bury the fetus in the back yard of a home in Armada Township, Mich.

The parents apparently did not know of the pregnancy until the teen miscarried, police said.

Investigators with the Michigan State Police Post in Richmond exhumed the remains of the fetus from the back yard on Monday.

The remains were taken to the Macomb County Medical Examiner's office where an autopsy will be conducted to determine the cause of death and how long the mother had been pregnant.

No charges have been filed, but Smith said the two teens may face charges as serious as manslaughter.
