Woman kills 11-year-old daughter to keep her from having sex, deputies say

A 28-year-old woman stabbed her 11-year-old daughter to death Sunday because she thought the girl was having sex with men, according to an arrest affidavit.

Rosa Alcides Rivera faces first-degree murder charges in the death of her daughter, Aleyda.


Officials said the incident began at a home on Citadel Drive, where Rivera had accused her mother’s boyfriend of having sex with her daughter. Witnesses told officers that the girl had denied having sex with him, the affidavit said.

According to officials, Rivera said she killed her daughter to prevent her from having sexual relations with men. She said she believed her daughter was having sex with men because she “smiled different,” according to the affidavit.

Mina said there appears to be no validity to Rivera’s claim that her daughter was sexually active.

“We don’t believe it’s credible,” Mina said.

Rivera also told detectives she attempted to make her daughter comfortable while she was stabbing her, according to authorities.

“We’re all parents, we’re all mothers and fathers, and these cases are horrific and tragic, especially any time a child is killed, and then to know that this child was killed by a mother. Basically, a mother is the first line of defense to this sometimes very cruel world,” Mina said. “It’s very very hard on all of us in the community.”

Officials said Rivera then harmed herself, resulting in the cuts to her arm, before she arrived at the hospital.

Although authorities did not say if Rivera had any prior contact with law enforcement, he said the incident comes as a reminder to report suspected domestic violence.

“I think the message is that domestic violence continues to happen not only in this community, obviously across the nation. When people see things, or notice things they need to call the authorities so that … we can stop these tragedies before they happen,” Mina said.
