POLSON, Mont. -

A northwestern Montana man was arraigned on charges he tried to hire someone to kill his ex-girlfriend to prevent her from testifying that he raped her.

KERR-AM reports defense attorney Ben Anciaux entered not guilty pleas Wednesday on behalf of 56-year-old Dennis Hobbs. Hobbs is charged with solicitation of deliberate homicide, stalking and tampering with witnesses and informants.

Lake County prosecutors allege that after Hobbs posted bond in the rape case, he drove by his ex-girlfriend's residence and her place of work, sent her flowers, made hang-up phone calls and several times asked the nephew of the then-Ronan police chief if he could find someone to kill her.

Anciaux didn't challenge Hobbs' $5 million bail.

District Judge James Manley scheduled Hobbs' trial for Aug. 18.
