East Orange Man Pleads Guilty in Disappearance, Death of his Child’s Mother

East Orange

Yesterday an East Orange man, charged with the death of his estranged girlfriend and the kidnapping of their son in an incident that resulted in a widely broadcasted Amber Alert last July pled guilty and is facing a 30-year prison sentence Union County Prosecutor William A. Daniel announced Tuesday.

According to Prosecutor Daniel, Tyler Rios, 27, of East Orange, pleaded guilty Monday to aggravated manslaughter and desecrating of human remains in the death of 24-year-old Yasemin Uyar.

Prosecutor Daniel stated that the July 2021 incident that resulted in a widely broadcasted Amber Alert launched a multi-state investigation which led to the recovery of the child and the discovery of Uyar’s body in Tennessee.

An investigation led by the Union County Prosecutor’s Office – and assisted by members of the FBI’s Newark Field Office and satellite offices, the New Jersey State Police, and the Rahway Police Department – led to Rios being identified as the suspect in the case after their son Sebastian Rios did not show up for daycare on July 9 and Uyar did not arrive for scheduled work shifts, according to Union County Assistant Prosecutor Robert Grady, who is prosecuting the case. 

A welfare check was conducted on Uyar’s home by members of the Rahway Police Department, but no one was found inside, Grady said.

Shortly thereafter, the State Police issued an Amber Alert that was sent to privately owned cell phones, broadcast on electronic billboards along highways in New Jersey and beyond, and widely shared via social media.

Through the relentless efforts of the Union County Prosecutor’s Office and the above agencies — as well as a result of the extraordinary assistance from the Putnam County Tennessee Sheriff’s Office and the FBI’s Memphis Field Office and satellite offices – Sebastian Rios was found unharmed in Monterey, TN on July 10, when Tyler Rios was taken into custody without incident. 

Later in the day, investigators located Uyar’s body in a wooded area nearby, off of Interstate I-40.

An autopsy performed on Uyar revealed that her death resulted from strangulation and blunt force trauma.  

The investigation subsequently revealed that, on July 8, Rios killed Uyar in her Rahway home before placing her in the trunk of his car, then taking his son and fleeing to Tennessee.

Sentencing in the case has been tentatively scheduled for Friday, June 10, at which time the State will request a term of 25 years in state prison pursuant to the No-Early-Release Act (NERA) -- which requires persons convicted of certain violent crimes to serve 85% of their sentence before being eligible for parole – on the aggravated manslaughter charge.  

The State will also be seeking a five-year term on the desecration count to run consecutive to the manslaughter charge.
