The jury, which convicted Staff Sgt. Delmar G. Simpson exactly one week ago after 31 hours of deliberations, took about 2 1/2 hours to reach a decision on his sentence on 18 counts of rape and 34 other offenses, mostly other forms of sexual misconduct.

He could have been sentenced to life in prison on a single rape conviction.

The five-man, one-woman panel also ordered Simpson be dishonorably discharged at a reduced rank of private E-1.

Maj. Gen. John E. Longhouser, commander of the Aberdeen Proving Ground, must approve the sentence. He may reduce it but not add to it.
