LISANDRO OLMOS, ARGENTINA, May 28, 2009 (LifeSiteNews.com) - An 18-year-old Argentinean has been arrested for murdering his mother and brother in a fit of rage provoked in part by his mother's opposition to sodomy, say Argentinean police.

The young man, whose name has not been revealed by the media, reportedly confessed to police that "his mother had not accepted" his decision to have sexual intercourse with men, "and for that reason the aggression and yelling began" according to the Argentinean publication Clarin.

"In recent weeks, the situation worsened because he had been prohibited too often from leaving the house and receiving his friends," Clarin reports.

After shooting his mother and brother in the head on Tuesday, the adolescent called the police, claiming that assailants had entered the property and committed the murders. However, inconsistencies in his story, the absence of any theft, and testimony from neighbors led police to suspect the young man of committing the crime.  He confessed under questioning.
