Former Metro police officer Deon Cartmell has been sentenced to serve 18 years in prison for the March 2010 shooting death of his wife, Shari Cartmell.
Judge Randall Wyatt sentenced Cartmell at a Friday morning hearing. The sentence is to be served at 100 percent.
A Davidson County Criminal Court jury convicted Cartmell, 25, of second-degree murder on Aug. 26 after nearly six hours of deliberation. He faced a sentence of between 15 to 25 years.
Cartmell had claimed his 24-year-old wife accidentally shot herself while the two were alone at their Saunders Avenue home on March 16, 2010.
During his brief time on the police force, Cartmell, a 2009 graduate of the police academy, patrolled the East Precinct before being decommissioned the day after his wife died.
The police department placed him on administrative assignment during its investigation. He later resigned.
Police arrested Cartmell on May 28, 2010, the same day a grand jury indicted him.
