A woman from Colorado is accused of collaborating with her boyfriend to murder his two young children—one of whom was hidden in a container filled with “hardened concrete,” while the other was kept in a car trunk for almost a decade.

Corena Minjarez, 37, from Pueblo County, is charged with two counts of first-degree murder of a victim under 12 years old by a person in a position of trust and two counts of corpse abuse for the 2018 deaths of Jesus Dominguez Jr., 5, and Yesenia Dominguez, 3, based on court documents. Her boyfriend, Jesus Dominguez, 37, accepted a plea bargain in July for second-degree murder and agreed to testify against Minjarez, according to The Pueblo Chieftain. He reportedly testified last week, narrating how he and Minjarez were using drugs and maltreating the children, with Minjarez allegedly having difficulties potty training both of them with Dominguez.

As reported by the Chieftain, Dominguez stated that Minjarez compelled the children to sit inside plastic bags while traveling because she wanted to avoid urine stains in her car. In one alleged incident leading to the children’s deaths, Minjarez used a high-pressure water nozzle at a self-service car wash on Jesus Jr., causing cuts near the boy’s groin area, according to his father.

Dominguez narrated that on March 14, 2018, as they drove the children to school, Yesenia had an accident and was made to sit on the car floor inside a trash bag when the 3-year-old apparently stopped breathing in the backseat, reported the Chieftain. Despite considering taking her to a nearby hospital, the couple decided against it due to visible abuse signs she had, including bite marks and injuries to one of Yesenia’s hands, which Dominguez alleged Minjarez inflicted months prior.

With Jesus Jr. still in the car, Minjarez and Dominguez reportedly went to a house on Sundance Court, placing Yesenia’s body in a tote, then later moved her into a suitcase and placed it in Minjarez’s trunk after an eviction, according to Dominguez and the prosecutors. Dominguez claimed his son never questioned what had happened to his sister.

Weeks later, the pair allegedly lived in Minjarez’s Pontiac, where Yesenia’s body was located, according to Dominguez. The girl’s remains could be smelled “little by little” as the couple began snorting Percocet and methamphetamine inside the vehicle, with Jesus Jr. staying inside the car with them as well, his dad alleged.

The boy showed progress with his potty training but started “going backwards,” according to Dominguez, which allegedly caused more problems with Minjarez.

The couple was out picking up drugs in April 2018 with Jesus Jr. when Minjarez allegedly told Dominguez that the boy had stopped breathing while sitting in the backseat, according to the father. Dominguez said Jesus Jr. was sitting near plastic bags and blankets, and his lips had turned purple. The pair, once again, refused to go to a hospital and instead took Jesus Jr. to a field near the Pueblo Dam, where they allegedly stuffed him inside a suitcase with layers of trash bags, according to Dominguez.

Prosecutors say Minjarez and Dominguez allegedly transported Yesenia’s body to a unit at the Kings Storage facility at 617 W Sixth Street in Pueblo and stowed Jesus Jr. away in the trunk of the Pontiac, which was eventually taken to a local scrapyard. The couple began living out of the storage unit until they were evicted, leading Minjarez’s mother to discover a trash can filled with concrete while helping them clear everything out, police reported.

Minjarez’s mother ended up being the one who called the cops in January 2024 after she grew suspicious of the container inside Minjarez and Dominguez’s storage unit, according to prosecutors. She allegedly told investigators about a number of disturbing signs she noticed over the years, including a “foul smell” coming from Minjarez’s car in the summer of 2018.

On Jan. 20, officers responded to Kings Storage and allegedly found the container.

“The metal container was searched, and the remains of a child were located within the container,” Pueblo Police said in a press release. It was Yesenia and her body was badly decomposed, with her autopsy report listing the manner of death as “homicidal violence” but with no cause due to the severity of the decomposition. Police located Jesus Jr.’s body two weeks later.

“During the investigation detectives located a vehicle belonging to a Corena Minjarez at a local scrap yard,” police said. “On February 6th, 2024, Police executed a search warrant on that vehicle. Police located a suitcase in the trunk of the vehicle. In the suitcase were the remains of a young male child.”

An autopsy revealed that the remains were those of Jesus Jr., and that he had also been a victim of “homicidal violence.” The investigation revealed that no missing person reports were ever filed for him or Yesenia.

Dominguez, who accepted his plea deal on July 10, allegedly had a tumultuous relationship with Minjarez, according to the Chieftain, citing testimony from local police detectives at an October 2024 preliminary hearing.

As the relationship soured, prosecutors say Minjarez allegedly took her frustrations and anger out on Jesus Jr. and Yesenia, along with growing extremely jealous of the children’s biological mother. Family members of Minjarez allegedly told investigators they were concerned over Minjarez’s treatment of the kids before their deaths.

During a previous alleged incident, Minjarez had locked Yesenia in a room and forced her to finish eating a carrot. Her own teenage son allegedly got upset at her for being too hard on the kids, according to prosecutors.

A friend of Minjarez’s told cops she allegedly confessed to hiding Jesus Jr. and Yesenia’s bodies in 2018 after they both died “the exact same way” of accidental causes.

Minjarez’s trial is scheduled to proceed through Aug. 29, per the Chieftain. Dominguez is due to be sentenced on Sept. 12.
