A Baker man convicted April 9 in the 2009 stabbing death of his wife, lawyer Chiquita Tate, in her downtown Baton Rouge office will not be sentenced Monday as originally scheduled, his lead attorney said Thursday.

Lewis Unglesby, attorney for Greg Harris, said he will be involved in a jury trial set to begin Monday and continue through the end of the month at Orleans Parish Civil District Court.

Lead prosecutor Prem Burns also noted that the presentence investigation report ordered by state District Judge Trudy White in Harris’ case has not been completed.

Unglesby and Burns said a new sentencing date has not been set.

An East Baton Rouge Parish jury found Harris, 40, guilty of manslaughter in the February 2009 stabbing death of Tate, 34.

Harris faces up to 40 years in prison. He stood trial on a charge of second-degree murder, which carries an automatic sentence of life in prison.

Harris was accused of stabbing Tate several dozen times in her third-floor office at the State National Life Building on Third Street where it intersects with Florida Street.

Tate’s body was found the morning of Feb. 20, 2009, after Harris called 911 and flagged down a police officer on patrol.

Harris told police he went to the building to check on his wife after she did not come home from work the night before.

Burns argued to the jury that Tate did not come home from work that night because Harris killed her there, putting an end to what she called the couple’s “very short troubled marriage.’’

They married in February 2008.
