(AP) – A registered sex offender faces trial next year on charges of raping two young girls who say their mother drove them to Wichita to have sex with the man.

KWCH-TV reports  a judge scheduled the trial for Jan. 9 after hearing testimony Friday against 47-year-old James Brown, who pleaded not guilty. Brown is charged with 10 counts each of rape and aggravated human trafficking.

The girls, now 13 and 14, testified their mother began drove them from Kansas City, Kan., to a Wichita motel about 40 times beginning in 2005 and forced them to have sex with the man. The younger sister said their mother became angry with the girls when they cried.

The mother is charged with the same 20 counts and will also be tried in January.
