TUSCUMBIA — In his sometimes emotional testimony today, Brian Lansing Martin said the shot that killed his father, Donice “Boo Boo” Scott, was fired while he and his father were fighting over a pistol.

Martin, 32, is being tried in Colbert County Circuit Court for murder in connection with Scott’s death outside his 1011 E. Second St. residence on May 11, 2011.

Martin took the stand at 11 a.m. and testified for about an hour, describing the events that led to the shooting. The testimony became more intense after lunch when Martin and his attorney, Billy Underwood, demonstrated for the jury what happened just before Scott was shot.

In front of the jury box, Martin portrayed his father while Underwood portrayed Martin. With his hand on Underwood’s neck, Martin used a flexible rod to demonstrate how Scott pressed a 28-inch samurai sword into Martin’s stomach.

Martin said he grabbed the sword to keep his father from “thrusting it” into his stomach. He said at one point, he took one hand off the sword and pulled a .40-caliber Glock pistol from a holster on his belt. As the two men struggled over the pistol, it pistol. As they fought, the pistol fired and the bullet struck Scott in the chest, Martin testified.

The defense rested its case just before 5 p.m. today. Attorneys will deliver their closing arguments when the trial resumes Friday at 9 a.m.
