It is rare for a woman to be indicted for genocide charges since the Gacaca trials started here, reports Hirondelle News Agency.
The road blocks were essentially controlled by men.
Mrs Uwamwezi is charged for illegal weapon's possession, planning of genocide and murder, according to the League for Human Rights in the Great Lakes Region (LDGL).
She is also prosecuted for having refused to let into her home Tutsi children who were being chased by militiamen.
During her first appearance last Sunday, she denied having refused these children, instead stated that she hosted them along with their mother,Marie Mukarwego, on the night of 6 April 1994 and that they had left her home three days later on their own volition.
Three prosecution witnesses testified that the defendant had indeed refused these people entry into her house. However the claim was disputed by two defence witnesses.
Uwamwezi is on trial alongside her father Sylvain Muhizi and two of her brothers.
The gacaca courts are charged with trying the majority of the persons allegedly responsible for the genocide.
The courts are not presided by lawyers but by people chosen from among the community for their integrity.
According to UN estimates, about 800,000 Tutsis and moderate Hutus were killed in the genocide.
The only woman indicted by the International Criminal Tribunal for Rwanda (ICTR) is Pauline Nyiramasuhuko, former Minister for the Family and Women's Development, accused of genocide and violations of Geneva Conventions.
Her trial, along with five other co-defendants is currently underway at the Arusha-based tribunal.
