Both parents still in a state of shock, and now also having to process the news that Breana was pregnant. Dave and Nicole only found out after her death, as Dave added:

"We didn't know anything about it."

Found in a dumpster on Sunday just off a business near their home after dying from multiple stab wounds, the teen accused of her brutal murder, Aaron Trejo, 16, entered a plea of not guilty during his court hearing on Tuesday.

Dave Rouhselang lamenting the death of his daughter said:

"She was the nicest sweetest most innocent girl you'd ever meet."

Aaron got charged with murder and feticide. He told the court that he and Breana fought about the pregnancy and he was angry she had not had an abortion, and couldn’t because she was too far along in the pregnancy.

On December 12, Arron Trejo’s aunt, Alexzaundra Patton-Manu, said during an interview with The Daily Beast, that she and the whole family is in shock. Manu added that Aaron “was always a private person” and had “no clue” as to what was going on. Alexzaundra added:

“This is not him. This is not in his character.”

Charging documents stated that Aaron told detectives he thought about killing Breana for about a week before he went through with it.

Breana went missing on Saturday night around midnight. Aaron stabbed her multiple times in the heart and wrapped her body in a plastic bag before he threw her in the dumpster. Aaron than discarded her phone and the knife in the river.

The autopsy also revealed that her scarf was wrapped around her neck tight enough that it's possible she was being strangled before her death.

Aaron appeared before the judge via video conference and being charged as an adult. However, the state prosecutor cannot ask for the death penalty because Aaron committed the crime before he turned 18. Scheduled to appear in court again on December 19, Aaron will remain jailed without bond.

Breana’s grieving family and friends will commemorate her life with various events that will lead up to her funeral on December 17, 2018.
