WARREN, Mich. -- A 27-year-old Warren woman has been sentenced to life in prison without parole for first-degree murder in the death of her 2-year-old son.

Macomb County Circuit Court Judge John Foster also sentenced Crystal Tamara Conklin to nine to 15 years in prison for first-degree child abuse.

The sentences will run concurrently.

A jury had found Conklin guilty last month.

Michael Sowards had returned home from work last June 11 to find their son, Sean, unresponsive.

Sean Sowards was treated for a closed-head injury and died two days later at a local hospital.

Investigators have said the boy had a fractured femur, two missing toenails and bruises all over his body.

Michael Sowards is being charged with child abuse in a separate case.
