FRESNO, CA – A Fresno woman was ordered to spend the rest of her life in prison, while her accomplice was handed two decades behind bars, for the 2022 murders of her teenage sister and infant niece, a killing that stunned the local community and authorities alike.
Yarelly Solorio-Rivera, 24, received life without parole Wednesday for shooting her 18-year-old sister, Yanelly Solorio-Rivera, and three-week-old niece, Celine Solorio-Rivera, as they slept in their Fresno home near Fruit and Jensen avenues. Her co-defendant, Martin Arroyo-Morales, 28, was sentenced to 19 years and 8 months after pleading guilty to two counts of manslaughter.
The fatal shootings occurred in late September 2022. Investigators determined that the attack was driven by jealousy and long-standing rivalry between the sisters. Prosecutors said Solorio-Rivera resented the attention her younger sister received after becoming a mother, ultimately leading to the deadly confrontation.
Officers arrived at the residence to find both victims with fatal gunshot wounds to their upper bodies. A Smith & Wesson 9 mm handgun, later identified as the murder weapon, was recovered during the subsequent investigation.
Within weeks of the killings, both suspects confessed their roles in the crime. Court documents and testimony revealed that Solorio-Rivera admitted to firing the fatal shots, expressing little emotion during her confession. Detectives described her demeanor as devoid of remorse throughout the investigation.
Authorities added that frequent arguments between the sisters had escalated in the days leading up to the murders. Previous police responses to the home included the confiscation of a firearm from Solorio-Rivera, reflecting the growing tension under one roof.
Arroyo-Morales admitted he was involved in the planning, telling investigators he was inside the house during the attack and took possession of the gun afterward. He was apprehended shortly after the killings, while Solorio-Rivera was arrested two days later.
Initially facing murder charges and firearm enhancements, Solorio-Rivera was at one point targeted for the death penalty. However, prosecutors later dropped that pursuit, noting California’s statewide moratorium on capital punishment.
During a pivotal court hearing last year, prosecutors played video of Solorio-Rivera demonstrating to police how she aimed and fired. The lead detective on the case testified to the deteriorating relationship between the sisters, who “used to be good friends” before jealousy overtook their bond.
The sentencing came after both defendants reached plea agreements with prosecutors. Solorio-Rivera was handed two consecutive life sentences for murder. Arroyo-Morales, credited with nearly three and a half years served plus good behavior, received 11 years for each count of manslaughter.
Superior Court Judge Brian Alvarez announced the sentences Wednesday, closing one of Fresno’s most harrowing cases in recent memory.
