PANAMA CITY, FL—Daniel Victor Smith, previously an inmate at the Federal Correctional Institution in Marianna, Florida, was sentenced to 120 months in federal prison on Wednesday, August 6, 2014, by United States District Judge Richard Smoak for aggravated assault with a dangerous weapon and aggravated assault resulting in serious bodily injury.

Earlier this year, a Panama City jury found Smith guilty of these charges after the government showed that Smith used a padlock tied inside of a tube sock to strike another inmate in the head repeatedly, which caused a hemorrhage to the frontal lobe of the inmate’s brain.

At the time of the assault, Smith, who claims to be a member of a prominent gang, was serving a 200 month sentence for second degree murder after he stabbed a man in the neck in Washington, D.C. in 2002. Smith’s sentence of 120 months in federal prison is in addition to the sentence he is serving for the 2002 murder.

The case was investigated by the Federal Bureau of Prisons and the Federal Bureau of Investigation. The case was prosecuted by Assistant United States Attorney Jason Beaton.
