COMMERCE CITY, Colo. -- Two families are hurting in Adams County after a man allegedly killed his fiancé's little sister Sunday night.

The man, 24-year-old Ezequiel Padilla-Villalobos allegedly called police and confessed to the murder that night.

According to court documents Padilla-Villalobos had ingested alcohol and cocaine Sunday night. His fiancé, FlorMaria Acosta sent him a text message asking him to pick up 14-year-old Gabriela Acosta from a family apartment in Broomfield.

Court documents say Padilla-Villalobos told police he had bad thoughts as they were driving. He took the girl to the area of 8690 Verbina Street in Commerce City and stabbed her to death.

FlorMaria Acosta told FOX31 Denver she feels responsible for the teen's death.

"It's hard. She was just 14," FlorMaria said. "She was a really sweet girl and she would always make me laugh. I feel like it’s all my fault. I feel like it’s my fault she died.”

When talking about Padilla-Villalobos, FlorMaria said, "It’s really hard for me because he’s the father of my baby and I just don’t have words to explain the emotion that I have for him.”

Padilla-Villalobos' parents did not want to comment, but were at the Acosta family's apartment Wednesday so they could all support each other. 

Padilla-Villalobos was in Adams County court Wednesday morning and is expected to be officially charged Friday.
