A doctor was unable to determine whether the St. Paul man charged with kidnapping and raping a 7-year-old girl last month is mentally competent to stand trial.

August J. Ruthaferd, 47, previously known as Mark S. Meihofer, will undergo a second evaluation to determine his mental competency.

Ruthaferd is charged in Ramsey County District Court with kidnapping and first-degree sexual assault.

His attorney, Monique Salvetti, said at a hearing Monday that Ruthaferd should be sent to the Minnesota Security Hospital in St. Peter for further mental health evaluation.

"[The doctor] was not able to make a finding," Salvetti said of the first report, which was submitted in court Monday.

Assistant Ramsey County Attorney Dawn Bakst agreed with the need for a second evaluation.

According to the criminal complaint in the case: Ruthaferd kidnapped and sexually assaulted the girl on May 5 after she briefly left her father's sight in the 300 block of Dayton Avenue.

Police found the girl about two hours later in Ruthaferd's room in a group home. She had been bound and gagged. She told authorities that he took naked pictures of her, forced her to smoke a substance and threatened her with violence. She tested positive for amphetamine.

Ruthaferd was charged in a 2011 sexual misconduct case in Anoka County, but was deemed mentally incompetent to stand trial and was civilly committed.

Anoka County District Judge Daniel O'Fallon acquitted Ruthaferd of the charges by reason of mental illness.
