TALLAHASSEE, Fla. -- The Florida Supreme Court is upholding a death sentence against a north Florida man convicted of killing his estranged wife.

A Duval County jury in 2011 found Lesly Jean-Philippe guilty of first-degree murder.

The high court on Thursday rejected arguments that evidence - including text messages from Jean-Philippe to his wife - should not have been considered by the jury. The justices also rejected arguments that he did not deserve the death penalty.

Authorities say Jean-Philippe had been staying with family in Rhode Island in August 2009, trying to clear his head, when he decided to return to Jacksonville to confront his wife.

Jean-Philippe went to 24-year-old Elkie Jean-Philippe's apartment, where he attacked her and her sister. Medical examiners found a total of 52 cuts on the wife's body.
