DETROIT (AP) — A suburban Detroit woman and her adult son have been charged in the slaying of her 60-year-old husband whose body was found in the trunk of a burning car.

The Wayne County prosecutor’s office says 67-year-old Beatrice Flint-Tennyson was arraigned Sunday on murder, tampering with evidence and disinterment and mutilation of a body. Her son, 46-year-old Delbert Flint of St. Joseph, Missouri, was arraigned Tuesday on the same charges.

Darvin Tennyson reportedly last was seen on March 19, 2016 after returning to his Farmington Hills home, northwest of Detroit. His body was discovered 11 days later by firefighters and police on Detroit’s eastside.

Defense attorney Cyril Hall, says that based on his review of the case he has no reason to believe his client, Delbert Flint, “is guilty of anything.”
