The Middlesex County man charged with kidnapping his own son, prompting an Amber Alert last week, has now also been charged with killing the boy’s mother, Union County Prosecutor William Daniel announced.

Tyler Rios, 27, of Highland Park, faces one count of first-degree murder in connection with the death of 24-year-old Yasemin Uyar of Rahway.

He previously was charged with first-degree kidnapping for the abduction of 2-year-old Sebastian Rios, who appeared physically unharmed when father and son were found in a Tennessee motel together early Saturday.

Later that same day, Uyar's body was found in a wooded area off Interstate 40, authorities said.

The tragedy unfolded last Friday, when the Union County Prosecutor’s Office – assisted by the FBI Newark Field Office, New Jersey State Police and Rahway Police – identified Rios as a suspect when his toddler son did not show up for daycare and Uyar missed work.

Uyar's mother previously told New Jersey 101.5 that she made the 15-hour round-trip to Tennessee on Sunday to bring Sebastian home.

Tyler Rios remained in custody in Tennessee as of Thursday, pending extradition back to New Jersey. He would then be slated for a first appearance and detention hearing in Union County Superior Court.
