The notice was filed in the Texas Court of Criminal Appeals by Guyger's lawyer, Michael Mowla, earlier this month -- just weeks after Guyger, 31, was convicted and sentenced to 10 years in prison.

The Texas appellate rules require defendants to file a notice within 30 days after a sentence is imposed or suspended in open court should a new trial be sought, according to the Fort Worth Star-Telegram.

The notice does not specify the basis of a possible argument for appeal. Mowla did not immediately return ABC News' request for comment.

Guyger shot and killed 26-year-old St. Lucia native Botham Jean on Sept. 6., 2018, after mistaking his apartment for her own as she returned home from work. Jean was eating ice cream when he was shot.
