BONAIRE, Ga. — Bo Dukes now faces a dozen charges, including rape and kidnapping, after an alleged crime spree on New Year's Day.

A Houston County grand jury on Tuesday indicted Dukes on a dozen charges.

Warner Robins police said Dukes kidnapped two women on Jan. 1, took them to his Bonaire home, and sexually assaulted them. He also threatened the women with a gun, police said.

According to the new indictment, Dukes is now charged with:

-- One count of rape;

-- two counts of aggravated sodomy, involving both women;

-- two counts of kidnapping

-- two counts of aggravated assault with a dangerous weapon. According to the indictment, Dukes pointed a Browning 20-gauge shotgun at both women and threatened to kill them;

-- four counts of possession of a firearm during commission of a felony;

-- and one count of possession of a firearm by a convicted felon.

Dukes went missing after the New Year's Day incident and was arrested four days later at a relative's home in Irwin County.

No trial date has been set for Dukes on either the Houston County case or the Ben Hill County charges.

His friend, Ryan Duke, is scheduled to stand trial in April for killing Grinstead, an Irwin County teacher.

The two men were charged in early 2017, more than 11 years after she went missing.
