An Orlando woman stabbed her 11-year-old daughter more than a dozen times to prevent the child from being promiscuous and having sex with multiple men.

Police say Rosa Rivera, 28, stabbed Aleyda Rivera multiple times and then sat with her in a car “for hours” while the girl bled to death.

Family friend Bianca Fernandez tells WESH2 News she was in a home on Citadel Drive when Rivera arrived and pounded on the front door around 7:30 a.m. on Sunday.

Fernandez said Rivera tried to force her way into the home but she pushed Rivera out and slammed the door.

Fernandez said Aleyda was in Rivera’s car, and she seemed fine at the time. She said a relative talked to Rivera and then mother and daughter left.

Fernandez said Rivera returned to the house a short time later and dumped the girl’s body on the lawn. Rivera then loaded Aleyda back into the car and sped off.

The Orange County Sheriff said Rivera drove to Winnie Palmer Hospital, where Aleyda was pronounced dead on arrival.

Hospital security detained Rivera after she wielded a blood-soaked pocket knife.

“My baby is gone,” Rivera told first responders, according to an arrest report.

Aleyda suffered 15 stab wounds to her back and a defensive wound on her right arm.

“She was a beautiful little girl,” said Fernandez, who added that the girl’s grandmother is “devastated.”

Fernandez said Rivera and her daughter moved to Orlando from Texas in December. She said Rivera’s mother paid her rent and bought her a car.

According to a criminal complaint, Rivera admitted to stabbing Aleyda in her car. She said she believed the girl was having sex with men because she “smiled different.”

Fernandez said none of the allegations made by Rivera about her daughter were true.

“Since she’s been here she’s just been going crazy,” said Fernandez.

The Orange County Sheriff said they don’t believe any of the claims of alleged sexual abuse.

Aleyda would have turned 12 later this month.

Rivera was charged with first-degree murder. She is being held in the Orange County jail without bond.
