Elinor Indico, 30, is accused of murder in the stabbing death of her pregnant sister-in-law in this Las Vegas apartment complex.

Elinor Indico, 30, faces charges of murder and voluntary manslaughter in the bloody slaying of her brother’s wife, Ashley Indico.

A neighbor told police Ashley’s 5-year-old son came to her door with blood on his hands.

“My mom is bleeding,” the boy told neighbor Stephanie Vasquez, the Las Vegas Sun reported.

A police report describes the allegations against Elinor Indico in the bloody killing of her pregnant sister-in-law Ashley Indico.

Vasquez rushed next door but couldn’t get in. Elinor blocked the door and told her to “get the (expletive) out of here,” according to a police report reviewed by Nevada reporters.

Vasquez told police she could hear Elinor yelling, followed by “orgasmic” moans, according to the report. Elinor seemed to be enjoying what she was doing to her sister-in-law, the document said.

Ashley lay dead inside the apartment. An autopsy report showed Ashley was stabbed at least three times in the neck, once in the bicep and once in the ankle, Fox 5 reported.

Her unborn child — due in about a week — was also killed. Her 3-year-old daughter was sitting in the bathroom.

Elinor was treated at University Medical Center for two shallow stab wounds on her stomach.

Aristeo Indico had let Elinor, his sister, move in with his young family but reportedly planned to kick her out when she broke his two rules: Get a job and quit using drugs, the Las Vegas Sun reported.

Neighbors said the tension was building between Elinor and Ashley built as the move-out deadline loomed.

Elinor reportedly told detectives she was only defending herself, claiming her sister-in-law went “stab crazy.”

The husband told police he and his sister were trained in martial arts and his sister owned a Chinese fighting knife, made with blades on both ends.
