Investigators say Idalis Smith, 18, and her stepfather, Greg Dosson, 34, were shot at Dosson's house where Smith succumbed to her injuries. Dosson was transported to the hospital for treatment.

Victim impact statements from survivors of loved ones taken by homicide are typically and understandably bitter and filled with anger, but that wasn't the case in a Baton Rouge courtroom at this week's sentencing of Idalis Smith's killer.

Smith's father, who is imprisoned, penned a remarkable letter to the killer, Quintin Marcel Thomas, that was read in state District Judge Richard Anderson's courtroom on Tuesday shortly before the judge sentenced Thomas  to 40 years in prison in the March 2015 shooting death of the 18-year-old Smith.

"After re-evaluating my life I realize I was no better than you," Cedric Spears reflected in his letter written from prison. "I made foolish choices as well in my lifetime. And in the midst of my troubles I called out for help from God and He heard me and answered my prayers."

Spears said he knows Thomas has cried out for God's help many days and nights and "made all kinds of promises if He gives you another chance."

"Well today your prayers have been answered cause it was God who touched the hearts of me and my fiancée to come in agreement to give you another chance, even though you didn't give our daughter one."

Thomas, who was charged with second-degree murder in Smith's killing and attempted second-degree murder in the wounding of another person, pleaded guilty in September to manslaughter and the attempted murder charge with the understanding he would be given a 40-year prison term. A second-degree murder conviction would have carried a mandatory life sentence.

Spears warned Thomas that he'd better keep the promises he made to God "whenever you felt like your life was gone forever. Cause if you don't God has a way of dealing with a person who reneges on his promise/word."

After East Baton Rouge Parish District Attorney's Office victim assistance counselor Maddie Devenney finished reading the letter, Thomas, 29, turned to Chandrikka Smith — Idalis Smith's mother and Spears' fiancée — and said, "I hope you can find it in your hearts to forgive me."
