ECORSE, Mich. -- A 19-year-old has been charged with three counts of criminal sexual conduct after having a relationship with an 11-year-old girl, police said.

Blake Blythe of Ecorse is accused of having a relationship with the girl and getting her pregnant last summer.

"Not guilty by reason of insanity. He will be sent to forensics center in Ypsilanti," Richard Glanda, Blythe's attorney said.

Blythe's mother and the girl's mother are also charged because they knew about the relationship. Police said both mothers consented to the two having sex.

Both women have been charged and convicted of contributing to the delinquency of a minor and received one year probation. They can not have unsupervised contact with any minor under the age of 17.

According to Glanda, the 11-year-old was removed from the house, along with a younger brother. Neither of them can have unsupervised contact with their mother. The baby is with the 11-year-old mother.

Blythe is being held on a $1 million bond an could be sentenced to life in prison.
