A California couple will be spending significant time away from each other — behind bars — for the vicious double homicide of a young mother and her newborn baby girl, prosecutors told Law&Crime.
During a Wednesday morning hearing in which neither defendant said a word, Yarelly Solorio-Rivera, 24, was sentenced to life in prison without the possibility of parole. Her accomplice, Martin Arroyo-Morales, 28, was sentenced to just shy of 20 years behind bars.
The underlying incident occurred in late September 2022, at a residence located near the intersection of Fruit Avenue and Jensen Avenue in Fresno — a large city in the San Joaquin Valley.
On the morning in question, Solorio-Rivera carried out the shooting death of her sister, Yanelly Solorio-Rivera, 18, and her sister's 3-week-old child, Celine Solorio-Rivera.

The woman's culpability was not long in doubt.
By November 2022, the older sister and her boyfriend confessed to their roles in the double slaying, according to then-Fresno Police Department chief Paco Balderrama, The Sacramento Bee reported.
The teen mom and her baby were shot in their upper bodies as they slept, in a crime motivated by sibling rivalry, police said. Detectives also later recovered a 9 mm Smith & Wesson handgun used in the slayings.
"We saw no remorse whatsoever, no guilt, no apprehension," Balderrama told the paper. "I've never seen something like this."
The shocked law enforcement officer — who has since moved on to lead the Oklahoma City Police Department — contextualized the slaughter of the family members in comments to the Bee.
"We see a lot of violence in Fresno. Typically it's risky behavior or gangsters shooting each other, and to a certain degree you expect that violence," he went on. "But you don't expect it from your own sister, and you certainly don't expect it against a 3-week-old child."
At the time, both defendants were charged with two counts of murder, two enhancements for the use of a firearm causing death, and special circumstances of multiple murder, the Fresno County District Attorney's Office announced in a press release.
In May 2023, during a hearing, prosecutors played the woman's taped confession before the judge overseeing the case, according to a courtroom report by Fresno-based ABC affiliate KFSN.
"Can you show me how you were pointing it?" a Fresno Police detective asked the female defendant in the video.
"Like this," Solorio-Rivera responded, mimicking a pointing stance. "I was like this, probably like that."
The detective went on to ask: "Did you mean to shoot her in the face?"
To which Solorio-Rivera replied: "Did I mean to shoot her?"
"In the face?" the detective asks again.
The woman answered: "Yeah."
During that hearing, the lead detective testified that the two sisters had frequently fought in the days and weeks leading up to the younger sister's death, but said they "used to be good friends."
A prior police call to their shared residence resulted in a firearm being taken from the eventual sister killer, the detective told the court.
Finally, the elder sister grew beyond jealous of the attention her younger sister and the baby were receiving, police said. Solorio-Rivera relished the idea of such attention being heaped on her and her own children. So, eventually, the envious sibling hatched a plan.
Well after the violence — and being caught on video as well as an increase in reward money announced by the sheriff's office — Arroyo-Morales admitted he was in the residence that day, that he was part of the plan, and that Solorio-Rivera gave him the gun after the shooting.
The man was arrested first, the woman was arrested two days later.
"We have the murder weapon — a Smith & Wesson 9 mm handgun — and we have a motive: jealousy and sibling rivalry," Balderrama said during a press conference at the time of the arrests.
In October 2023, prosecutors announced their intent to seek the death penalty against Solorio-Rivera, according to The Fresno Bee.
As the legal system slowly churned, those plans went by the wayside — and would have largely been a death sentence in name only, as the Golden State has long had a moratorium on capital punishment.
On Wednesday morning, the two defendants were sentenced as part of a negotiated settlement, the district attorney's office told Law&Crime.
During the hearing, Fresno County Superior Court Judge Brian Alvarez sentenced the woman to two counts of life for each murder charge.
The woman's after-the-fact accomplice pleaded guilty to two counts of manslaughter. He was sentenced to 11 years for each count but with nearly 3 1/2 years of time served and good behavior credits assessed against his sentence by the court.
