The Mississippi Supreme Court will not hear the appeal a former employee of the federal Transportation Security Administration in Mississippi who was convicted in the 2011 death of a co-worker.
Ruben Orlando Benitez was convicted in Harrison County in 2013 for the fatal stabbing of Stacey Wright, who was killed in her home. He was sentenced to life in prison.
The state Court of Appeals upheld his conviction last year. The Supreme Court declined Thursday to hear the case.
Prosecutors say Benitez told authorities that he killed Wright after the two argued about her wanting to end their affair. Prosecutors say she was stabbed 11 times.
Both had worked for the TSA, providing security in airports.
The Appeals Court denied Benitez' argument that he acted in the heat of passion.
