Timicca Jadean Nauta, the 15-year-old girl who was killed by a suspected burglar in her Dededo home in the summer of 2018, was raped, new court documents allege.

Rape allegations have been added to the charges against Brandon Michael Acosta, the 24-year-old who has been detained for months in the teen's murder case.

The Okkodo High School freshman was found dead on June 16, 2018.

A superseding indictment filed on July 12 charged Acosta with first-, second- and third-degree criminal sexual conduct, each with a special allegation of possession or use of a deadly weapon.

Acosta is expected to answer to the new set of charges, which also include murder, assault, burglary and home invasion, on July 17 during an arraignment in the Superior Court of Guam.

According to the superseding indictment, Acosta committed sexual contact while committing aggravated assault.

Nauta's body was discovered on the side of her bed with her face down. Blood trailed from the wall opposite of her body, toward her face, and was also seen immediately around her body and on a wall behind her. 

An autopsy conducted two days later found that the girl sustained five lacerations from a sharp blade: two on the left side of her face, behind her ear, on her left index finger, on the left side of her neck and on her right shoulder blade.

However, a rape kit was not used on Nauta, according to past statements from Dr. Aurelio Espinola, who was Guam's chief medical examiner at the time. A rape kit was not necessary, Espinola has said, because Nauta was found fully clothed.

”I did not do any DNA because, in my opinion, it was not necessary because the girl was fully clothed,” he said in the immediate aftermath of the teen's death. "I did not do it because it’s useless."

Fred Gange, the brother of Nauta's grandmother, challenged that assertion. Gange has said his grandniece was wearing only a blouse and an undergarment when she was discovered.

The Post has asked the Office of the Attorney General where the rape charges stemmed from. 

"We presented additional evidence to a grand jury who indicted on the new charges. Evidence received by our office is part of an ongoing case," said Carlina Charfauros, spokeswoman for the attorney general. 

Acosta was initially arrested on burglary charges after witnesses informed police of multiple burglaries in the area.

While detained, Acosta reportedly confided in at least one other inmate that he killed Nauta, according to earlier court documents.

Acosta allegedly blamed the burglaries on his drug addiction, stating to police that he does things he normally wouldn't do when using methamphetamine, according to court documents.

Nauta lived in a house with very little security, in a room she reportedly built with her own two hands, a room that from the outside resembled a makeshift shed.

Acosta allegedly told police that he went into Nauta's room, which was dark, and that the girl startled him. 

Killing Nauta was not his intention, Acosta allegedly stated, and that he "merely made a mistake."

These earlier documents do not mention sexual assault. Acosta initially faced aggravated murder and home invasion charges and had pleaded not guilty to the charges. He allegedly committed the crime while on release on a family violence charge.
