A 23-year-old Shreveport man will be spending a long time behind bars.  Earlier this week, a Caddo Parish jury convicted Darrell Toubya Thomas on a charge of attempted first-degree murder. Jurors found him guilty of firing shots into a vehicle back in December of 2010, seriously wounding one of its occupants. This morning, Thomas was formally sentenced to 48 years in prison -- without benefit of probation, parole, or suspension. But that may not be the end of his sentence. Assistant District Attorney Jason Brown has filed a multiple-offender bill against Thomas, and Judge Mike Pittman has scheduled a hearing next Wednesday to deal with that matter. If Thomas is found to be a multiple offender, his sentence could be extended to as much as 100 years.
