Carolina Marquez sentenced for her role in the murder of Conzuelo "Nicole" Solorio-Romero

Salt Lake County District Attorney Sim Gill announced that on November 17, 2025 a Third District Court judge sentenced Carolina Marquez for her role in the murder of Conzuelo "Nicole" Solorio-Romero.

On February 6, 2021, Orlando Tobar and Jorge Medina-Reyes were instructed by Ms. Marquez to remove Nicole from an apartment owned by the defendant. Medina-Reyes and Tobar forced Ms. Solario-Romero from her residence at gunpoint into a vehicle. Ms. Marquez told them to kill some time, so they drove to the border of Wyoming and back. They then drove Nicole to Ms. Marquez's residence in West Valley City, where she was taken into the home at knifepoint by Tobar. Several individuals were present in the residence when they arrived, including Ms. Marquez. A witness told police that upon arriving at the residence Tobar questioned Nicole about providing information to the police that led to the arrest of Ms. Marquez's son. Multiple witnesses reported that Medina-Reyes then shot Nicole in the head, and that she was shot a second time in the head by Tobar. After the shooting, surveillance video from a restaurant owned by Ms. Marquez showed that Tobar, Medina-Reyes, Ms. Marquez, her son Fernando Marquez, and other individuals, were in Ms. Marquez's office for a period of time. Tobar then called someone known as "The Mechanic," later identified as Cristian Morales, to assist in disposing of Nicole's body. Ms. Marquez, Fernando Marquez, Tobar, Medina-Reyes, and Morales all returned to the West Valley City home where Nicole had been shot and began disposing of her body and cleaning the remaining blood. Nicole's body was wrapped in plastic bags, transported from the scene by Tobar and Morales, and left in a field in Tooele County.

On November 17, 2025, a third district court judge sentenced Carolina Marquez to 2-20 years for one count of second-degree felony manslaughter with a gun enhancement, and to 6 years to life for one count of first-degree felony aggravated kidnapping.

A statement from Nicole's sister was read by the state at Carolina Marquez's sentencing:
"Nicole wasn't just a random person you grew to hate; she was my sister, she was a mother, and she was my mother's daughter. And although you took her from us, you will never take who she truly was from us… I will follow your prison journey, and the moment you have a parole hearing, I will be there, reminding you and the system why you should not be out in our community with our children, our sisters, our mothers, and our society. You don't deserve any forgiveness from us, as we don't forgive you," said Jessica Romero-McDonald

Salt Lake County District Attorney Sim Gill released the statement below following the sentencing hearing:
"We mourn the loss of Nicole and sympathize with the pain that her family and loved ones have endured and will likely continue to face the rest of their lives. We hope that the conclusion of this case will help our community feel safer now that a judge has determined the defendant will spend years behind bars for her heinous crimes," said Salt Lake County District Attorney Sim Gill. "I thank our prosecutors, Morgan Vedejs and Anna Rossi Anderson, as well as our support staff, for their years of dedication to this case in bringing accountability for the family of Nicole and our community as a whole. This case involved the work of 29 law enforcement officials, led by detectives at the Unified Police Department. We appreciate their impeccable work that helped ensure justice could be served."
