CHARLES CITY (AP) -- Noel Miller, the mother of Evelyn Miller, surrendered to authorities before an arrest warrant could be served by the Floyd County Sheriff's Department.

Miller, 24, of Charles City, was charged with carrying a weapon after calling 911 last Christmas and when police arrived allegedly concealing a 6 1/2-inch kitchen knife in her sleeve. She pleaded not guilty to the charge in January.

She missed a court hearing Monday but later turned herself in, Sheriff Rick Lynch said.

Miller was released after posting a $75 cash bond in Floyd County District Court. She is scheduled to appear at a later date at a pretrial hearing, County Attorney Jesse Marzen said.

Authorities are still investigating the death of Miller's daughter, who disappeared July 1, 2005, from the family's apartment in rural Floyd County. The little girl's body was found several days later along the banks of the Cedar River. No arrests have been made in her death.
