Ex-girlfriend pleads guilty in fatal stabbing case

BUFFALO – A former Silver Creek woman has pleaded guilty in the murder case of her ex-boyfriend, Jesse Seneca, 20, who was found dead near a dirt road off of Route 438 on the Cattaraugus Indian Reservation in July 2012.

According to Buffalo media outlets, Jasmine Rios, 19, entered her plea in Erie County Court Thursday for the charges of second-degree conspiracy and two counts of first-degree hindering prosecution. She will be sentenced April 9.

Seneca’s half-brother, Cody Testerman, 23, was charged in the case in July 2012. He has pleaded guilty to first-degree manslaughter and is awaiting sentencing on March 14. Both Testerman and Rios face up to 25 years in prison.

Rios was indicted in the case in December after being extradited from Arizona.

The Erie County District Attorney’s Office said Testerman stabbed Seneca in an open field off of Brant Reservation Road. Rios allegedly helped hide evidence of the murder and provided false testimony to police.

Authorities declined to comment to Buffalo media outlets on a motive for the attack, but in court, Assistant District Attorney Gary Hackbush said Rios and Testerman drove to Seneca’s Irving home the night before the murder. Testerman and Seneca allegedly left the house early the next day and fatally stabbed Seneca in a field. Rios allegedly then helped bury the body.
