Did a Love Triangle Drive This Woman to Kill Her Twin?

Amanda Ramirez, 27, was arrested and charged in the slaying of her identical twin, Anna.

Did a love triangle lead Amanda Ramirez to allegedly stab her identical twin sister, Anna, to death?

Dressed in an orange jumpsuit, Amanda, 27, sobbed as she appeared in a Camden, New Jersey, courtroom Thursday, where she was ordered to remain in jail.

She is charged with first-degree aggravated manslaughter in Anna's death.

At first, authorities said Amanda denied having anything to do with Anna's death. Police said she later claimed she stabbed her sister in self-defense after Anna attacked her with a knife outside the Centennial Village apartment complex early Saturday morning.

But a witness who saw the fight painted a very different picture, according to police.

According to a statement read in court, the witness heard Anna yell, “Amanda, you stabbed me!” while she lay bleeding on the ground outside.

The same witness reportedly said that it was Amanda who produced the knife during an argument and warned her sibling, “Watch what I’m going to do."

The witness reportedly missed the moment Anna was stabbed as they tried to run downstairs to stop the argument. 

Amanda's lawyer, Igor Levenberg, pointed to that in court as he argued for her to be released on house arrest given she has a 20-month-old child at home. 

That request was denied, however.

A law enforcement official told The New York Times that the fight was over a man, and added that the man was not involved in the fight and was cooperating with authorities.

An aunt shared a similar account with the Times, saying that the two were "arguing about a boyfriend."

"She just went on a crazy trip, stabbed her and killed her," the aunt reportedly said. "... You couldn’t believe she would do that to her own sister."

Anna was mother to three children and "loved to spend time with her family," according to her obituary.

Amanda's lawyer told Inside Edition she is presumed innocent of the charges. Her next court date is scheduled for July 31.
