A judge in Nicaragua has convicted three former police guards at President Daniel Ortega's home of raping a mentally disabled 12-year-old girl.

Judge Aleyda Irias will decide sentences for the men on Jan. 29. On Thursday, prosecutors requested prison terms of 15 years for rape and 12 years for sexual abuse against each. The sentences would be cumulative.

The attack occurred near Ortega's house last year when the girl went out to play in the rain with her dog.

The officers grabbed her and bundled her into a vehicle, where she was raped. The officers have been fired.

The girl's father testified that five officers were involved, but prosecutors said evidence could be found to charge only three.
