Tyler Rios, 27 of East Orange, pleaded guilty Monday to one count of first-degree aggravated manslaughter and one count of second-degree desecrating of human remains in the death of 24 year-old Yasemin Uyar, before Union County Superior Court Judge John Deitch.

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 9th 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, Tennessee on July 10th, 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 8th, 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, 2022, 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 5 year term on the desecration count to run consecutive to the manslaughter charge.
