"These types of crimes rock the soul of the community and destroy the innocence of our youth," Saginaw Police Detective Sgt. Joseph Dutoi said.
Angela Blackwell, 45, was being held in the county jail on two counts of first-degree criminal sexual conduct with a person under age 13 and one count of pandering, The Saginaw (Mich.) News reported Wednesday.
Johnnie Griffin, 67, was wanted on two gun charges and two counts of first-degree and one count of second-degree criminal sexual conduct with a person under age 13, Dutoi said. Police said they believe Griffin had left the area.
The assaults against Blackwell's granddaughter began in September and ended in February, occurring when the granddaughter visited Blackwell on weekends, Dutoi alleged. Police learned of the alleged assaults while investigating reports of similar crimes against Griffin, Dutoi said.
